Equivalent Apache2 Directives for Those From the Docker Nginx Documentation?
by James Bowery 15 Dec '20

15 Dec '20

The Docker documentation at: https://asynchronous.in/docker-mailman/#dependencies I've installed and enabled proxy_uwsgi for Apache and made a rough cut at a configuration for the lists.* subdomain in question but it's failing. What follows are the document's Nginx directives for which I would greatly appreciate the Apache2 equivalents. I'm attempting to move a mailing list off of Yahoo groups onto my hosted server using an Apache2's virtual host on the 'lists' subdomain: Setting up your web server: # Nginx configuration. location / { # First attempt to serve request as file, then proxy_pass http://172.19.199.3:8000; include uwsgi_params; uwsgi_read_timeout 300; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $remote_addr; } uwsgi: # Nginx configuration. location / { # First attempt to serve request as file, then uwsgi_pass 172.19.199.3:8080; include uwsgi_params; uwsgi_read_timeout 300; }

Data too long for column 'data' in workflowstate
by Morris Jones 14 Dec '20

14 Dec '20

I ran into this error attempting to add a user to a mailing list: (pymysql.err.DataError) (1406, "Data too long for column 'data' at row 1") [SQL: INSERT INTO workflowstate (token, step, data) VALUES (%(token)s, %(step)s, %(data)s)] [parameters: {'token': '7394fbf654b3faffc6a65eb95e0616eea6651b9e', 'step': 'do_confirm_verify', 'data': '{"pre_approved": false, "pre_confirmed": false, "pre_verified": false, "invitation": false, "address_key": "dorothyxxxxxxxx(a)gmail.com", "subscriber_key": 1, "user_key": "00201c01dcc443c3a0d8f6d1ea42e230", "token_owner_key": 1, "send_welcome_message": null}'}] In MySQL I see that column 'data' in workflowstate is VARCHAR(255), and the data in the query is 259 characters. If I have a moment I'll write a bug or patch ... but I'm not really current on schema migrations.

Hi, despite mailman is running as mailman user and the required periodic jobs have all been created in crontab for the mailman user, a permission denied exception for the digest file has been logged in mailman.log: Dec 14 11:31:42 2020 (399913) Uncaught runner exception: [Errno 13] Permission denied: '/var/lib/mailman3/templates/lists/...//list:member:digest:header.txt' The subdirectories and files of the templates subdirectory got the root owner and group: drwxr-xr-x. 3 mailman mailman 4096 Dec 12 17:58 templates drwxr-xr-x. 11 root root 4096 Dec 12 19:20 lists -rw-rw----. 1 root root 16 Dec 12 19:19 list:member:digest:header.txt How can this be avoided?

Importing config and archives only partially succeeded?
by Eric Broens 13 Dec '20

13 Dec '20

Today I have migrated about 30 mailinglists from mailman 2.1 to mailman 3.3.2 & Hyperkitty 1.3.3. Although no error responses were given when importing the 2.1 pck files, and neither for importing the archives, for about half of the mailinglists the hyperkitty webpage doesn't show any subscribers, nor archived emails. The imported members and other settings are correctly shown in the postorius page. Is there anything that I can verify why the archive is not shown on the hyperkitty page?The hyperkitty_email database table does contain the emails. Thanks in advance,Eric

troubleshooting hyperkitty
by Morris Jones 10 Dec '20

10 Dec '20

Working on a new installation -- lists seem to be working in terms of distributing postings. But none of the postings are appearing in an archive yet. I created a mailman-hyperkitty.cfg file in /opt/mailman/var/etc/. It has a base_url for the "hyperkitty installation," and I'm not sure where that's supposed to be. The comment says "This address will be used by Mailman to forward incoming emails to Hyperkitty for archiving." I set base_url to http://mailman.whiteoaks.com/hyperkitty (changing "localhost" from the example). It redirects to https:, I set new secret keys here and in mailman.cfg. No new posts appear, and nothing archive related shows up in mailman's log. The mailman qcluster is running. The runner=archive job is running. Can someone suggest a troubleshooting strategy?

Hyperkitty Recommended mySQL Database Setup & Archive Importing
by matthew＠alberti.us 10 Dec '20

10 Dec '20

Hi, I've been working for quite a while to setup a production mailman3. Using the docker containers, I have been pretty successful getting it to work. Part of the challenge now is that there are a lot of issues when importing archives from mailman2. This of course is more common on lists that are over 10 years old. From what I've been reading, it seems like Mailman3 expects the mysql database to use UTF8 encoding. It appears, by default, that when using the docker-mailman containers, that the character set is set to latin1. This may explain why there are lots of import errors, and maybe also why there are a lot of errors when threads are deleted in hyperkitty's UI. Is it the case that UTF8 is the preferred character set? I also saw some threads indicating that maybe utf8mb4 is more preferred. I'd like to try to change the character_set on the database, if that is advisable. Also, is Hyperkitty 1.3.4 officially released? I see that the list.org instance is using it, but the latest announce I've seen is for 1.3.3. Thanks. - Matt Alberti

Message moderatin without login
by Michael Lorenzen 08 Dec '20

08 Dec '20

Hi, are there any plans to allow message moderation without having to login to posterious? I am very pleased with the new web interface and the rest api, but i miss the ability to moderate messages either by mail, with different reply addresses to discard, reject or accept hold messages or by html links with one time codes to achieve the same. I tried to reply on the mail attachment with the confirm ... subject, but that did not seem to work (neither reject nor accept with approved: placed into the first line of the mail).

Moderated Signup with "info" box?
by chris＠zimmerman.to 08 Dec '20

08 Dec '20

Hi all, we have a mailman deployment that we are using for a private neighborhood community board. We have the list setup for moderated approval signup. The trouble is, when someone signs up, we only get a request with their email address. I would like to be able to use the web form, but have a "notes" field that would get submitted with the signup request. the notes field would be where the user would note name/home address. So when one of our moderators get the request, they can figure out quick who the request is coming from. Can anyone provide some guidance or assistance on how to make that happen?

Spam getting in for moderated list
by Quanah Gibson-Mount 06 Dec '20

06 Dec '20

I have a list that has the following settings: List members -> Hold: This holds the message for approval by the list moderators. Non-subscribers -> Silent discard And yet, spam emails from a spammer that signed up to the list are going straight through and being delivered. Is this a known bug in mailman 3.2.1? Example: <https://lists.openldap.org/hyperkitty/list/openldap-bugs@openldap.org/threa…> It even has this list header: X-Mailman-Rule-Hits: member-moderation and version is X-Mailman-Version: 3.2.1 I think it was sent via the web interface? User-Agent: HyperKitty on https://lists.openldap.org/ I checked the settings for this subscribed spam user, and it specifically says "list default" for moderation, so it should have been moderated.

Hi, The documentation https://docs.mailman3.org/en/latest/config-web.html includes a section on scheduled tasks that need to be included in cron. "runjobs" seems to be available only from "manage.py". Do these scheduled tasks need to be executed from the python virtual environment?If so, is there a way to do that directly from cron, or should I create a script for these tasks which can be called from by cron?

I am trying to change email "To" field to user's email instead of mailing list's email. e.g. "To: <user(a)gmail.com>" instead of "To: <mailman-users(a)mailman3.org>" I looked around old mailman configs they mentioned about adding OWNERS_CAN_ENABLE_PERSONALIZATION option in mm_cfg.py is this feature still available in mailman3 ? Can I do it via Postorius or REST API? Thanks.

Initial success: Mailman 3.3 integrated with Zimbra 8.8
by Morris Jones 02 Dec '20

02 Dec '20

I have a very old existing mail server running Zimbra 6 with a mailman 2.1 instance alongside. I needed to rebuild my mail server for some compelling reasons (the old server used outdated TLS protocol, I could no longer compile clamav, nothing could really be updated). The final straw was a lack of support for my old commercial SSL certificates. I patched in a letsencrypt certificate to get through the past six months. I'm in the process of commissioning a new mail server using an 8GB Linode, Ubuntu 18, Zimbra 8.8, and Mailman 3.3. A couple of days ago I had my first successful list creation, with user confirmation working by email. I have django running with uwsgi, and am using Zimbra's installed nginx proxy to reverse proxy http traffic to Postorius and Hyperkitty. Nginx is doing the SSL layer. The mailman core mta hooks are all done using Zimbra's "local configuration" technique. In theory I should be able to do Zimbra upgrades with a minimum of hassle. I've written up a "case history" of how it came together. I have a .rst file in a gitlab project here: https://gitlab.com/MojoLA/mailman3.3-zimbra-8.8-integration I suppose this is a crazy project, but it's worthwhile to me. (Mark, thank's so much for integrating the virtual domain maps. It took me about three days to recognize that they were the solution to bounced mails to list-owner@...) Now I can spend some time migrating my email accounts (only four) from the old server to the new one, and move a dozen or so mailing lists to the new mailman3 instance. I'll have to get accustomed to a new way to manage the mail lists, and already really like what I've seen. Thank you. :) Best regards, Mojo -- Morris Jones, Monrovia, CA BridgeMojo <http://bridgemojo.com> Old Town Sidewalk Astronomers <http://otastro.org> Mojo's Blog <http://mojo.whiteoaks.com>

12/24 hour clock ?
by Per Jessen 28 Nov '20

28 Nov '20

Hi all at openSUSE we have recently migrated to mailman3, and we seem to be having a couple of teething issues: a) hyperkitty and postorius both seem to insist on using a 12 hour clock format, no matter what the user has set. Is there a way of changing it system-wide ? b) overriding the default set of footers - despite having set the template "list:member:regular:footer" to empty for a specific list, I am still getting the default footers attached. We are using version 1.3.3. thanks Per Jessen

No styling for web apps?
by Morris Jones 27 Nov '20

27 Nov '20

I have most of a new mailman suite server built and working ... collectstatic gathered a good array of static files (uncompressed so far) nginx appears to be serving them successfully The Firefox developer tools show css and js files all being delivered But none of the postorius or hyperkitty pages exhibit any styling at all, only bare HTML elements. The Firefox inspector will show the available styles being requested and delivered (style.css, bootstrap, jquery, all the things). But if I use the inspector to look at the page, nothing has any CSS properties. I know I'm missing something simple. (Happy Thanksgiving!)

mailman 3.3.2 config file location
by Eric Broens 25 Nov '20

Hi, I am trying to install Mailman 3.3.2 in a python virtual environment, and don't understand why the following is happening.When executing "mailman info", it shows that "the config file is located in /etc/mailman3/mailman.cfg as is intended, hence "outside" the virtual environment. However, after having started mailman, and running "mailman info" again, the default (empty) config files seems to be created in the directory where mailman has been started:config file: /opt/mailman/mailman-suite/mailman-suite_project/var/etc/mailman.cfg This happens even when mailman is started with the option "-C /etc/mailman3/mailman.cfg".Does this mean that the config file needs to be located in a subdirectory of python's virtual environment?

How to strip DKIM headers on a domain level or a list level
by Stephen J. Turnbull 24 Nov '20

24 Nov '20

Rob Jenson writes: > I need to strip DKIM headers on the inbound messages to my list or > to my domain. Why do you need to strip DKIM headers? The standard specifies that an invalid DKIM signature must be treated the same as if there were no signature at all. So an invalid DKIM signature may be treated as spammier than a message with a valid signature, but that should not be treated differently from an unsigned message (as would appear after removing those header fields). I know this feature is in demand from list admins, but I've never seen convincing evidence that it's actually effective for any of the usual suspects (Yahoo!, AOL, Gmail), only for small domains with pigheaded admins who are proud of their non-conforming configurations, and announce that they are discarding messages which have invalid DKIM signatures. > What I do not understand from the documentation for Mailman 3 Core > is whether it is possible for my hosting service to set > remove_dkim_headers just for our domain. It currently is not possible. It probably could be made possible on a per-domain or per-list basis, but it's not clear to me why it would be useful to do so. If there really are non-conforming receivers out there, it's probably a good idea to strip host-wide. > If that is not possible, then the question becomes "is there a way, > in the list configuration, to strip the DKIM headers? It is possible, but that requires changing the list's processing pipeline to add that capability. I believe this is not difficult (I haven't done similar changes with Mailman 3 yet) but it does require the assistance of the host, and possibly imposes a future maintenance burden on the host. > We are munging the text of the message in Mailman, so the DKIM > headers from the original poster are invalid. As I explained above, both DKIM and DMARC are specified so that "no signature" == "invalid signature" for the purposes of spam processing. Are you sure that Yahoo! (or any other provider used by your subscribers) is treating invalid signatures differently from absence of signatures? The person responsible for Yahoo! MTA configuration is a well-known mail security expert who participated actively in the specification of all these protocols (and she also gave me a kitten, so I may be biased). > As far as I can see, our service provider is using ARC in our > Mailman configuration, but not signing the outbound messages with > DKIM. That surprises me. ARC isn't really a substitute for the MTA's own DKIM signature, at least not yet. > Therefore the DKIM signature from the poster's mail service > provider is sent out with their DKIM header, which seems to be > problematic. It shouldn't be. > If I understand ARC correctly, it is validating the DKIM signature > from the poster, creating a new signature and metadata indicating > that what it received was properly signed. That is correct. As far as I know, Yahoo! does participate in the ARC protocol and used to have conforming implementations of DKIM and DMARC. That doesn't mean you get a free ride: they may still have your IP on a blacklist from former owners of the IP, for example. Or your posts may "look like" spam for some other reason, or your lists may need more time to build up a clean reputation. But I need evidence more convincing than "list posts are recognized as spam" to believe that removing DKIM headers will help. (For example, my employer's filters regularly recognize messages from department heads as spam, even with DKIM signatures intact. ;-)

I am working through installing mailman3 on Ubuntu 20.04.1 LTS / apache 2.4.41 / postfix 3.4.13 and have a couple of questions. I've installed Django, cloned the mailman-suite repo, installed and tested apache with Mod_wsgi [ according to https://tecadmin.net/install-apache-with-python-mod-wsgi-on-ubuntu-20-04/ ] and it worked fine. Now I am at 'Setting up a WSGI' server in the MM3 instructions where it says I am to configure uwsgi.ini file. Does that .ini file go in /opt/mailman/mailman where other .ini files reside? In setting up the apache virtual server [ according to https://docs.mailman3.org/projects/postorius/en/latest/deployment.html?highl ight=apache#apache-with-mod-wsgi ] I do not find a postorius.wsgi which WSGIScriptAlias points to.

mailman services under systemd

First post, I'm building a new mail server as my tired old server can no longer meet security requirements. (It's long overdue.) I see where Torge Riedel is running the mailman service under systemd, but I'm having trouble doing that. I don't see a mailman option that doesn't detach as a daemon. Did I miss something? Anyone have a systemd service example I might pilfer?

Reply w/Email Clients - From: vs. Reply-To:
by j＠manygoodideas.com 20 Nov '20

20 Nov '20

I'm setting up a new list, and a number of new list members are reporting a problem with replying to the thread. Their email clients seem to ignore the Reply-To: field and instead use from From: field. When they use Reply All, the email is addressed to both the From: and Reply-To:. Reading through previous threads here, I've tried a number of things: 1) DMARC mitigation action is "Replace From: with list address" 2) For Alter Messages - Set "Reply goes to list" The goal is that we want a reply to go to the list, not the person posting. Since Reply-To seems to be ignored by some clients, I'm hoping there's a way to force the "From" field to become the list address. Thanks in advance for your suggestions!

Hi Everyone, I have a list that has other mailing lists as members. When a non-member posts to this list I receive a moderation message. After approving the moderation message I then receive a lot of other moderation messages for the sub-lists that are members of the "top-most" list (since the non-member is not a member of any of the sub-lists). Is there any way to approve a message for moderation once and have all sub-lists automatically approve the message? Thanks for your help with this and have a nice day! Peter

How can I allow members of list A to post to List B and vice versa

Hi, I am trying to setup Mailman3 for our school. There I have several groups (teachers, parents) that have their own mailling lists. But it also should be possible that the parents can sent mails to the teachers list and vice versa. The manual management via the non-members list will be very inconvenient and the command-line options that I saw so far do not include the import of non-members (mailman syncmembers and mailman addmembers). The best option I would like to have is to enter the name of List A in the non-members of List B an vice versa. All those nonmembers should not need to be moderated. How can I manage this? I would be very glad for your ideas. Best Mario

Customising hyperkitty and postorius
by peter＠chubb.wattle.id.au 19 Nov '20

19 Nov '20

Hi, I've put up a mailman3 instance, with hyperkitty enabled, and imported all my mailman2.1 archives -- it all seems to be working. How do I now customise the look and feel of my site? In particular, I'd like to render archived emails with a monospace font, and I'd like to change the colour scheme and styles of all the pages to match other pages on the same website. Peter C

Dealing with confirmation requests for unsubscribes
by Brian Carpenter 18 Nov '20

18 Nov '20

Hello List, I ran into the following issue for some mailman 3 lists that I am hosting: https://gitlab.com/mailman/mailman/-/issues/768 Since there is no way for a list owner to deal with a moderation request for an unsubscription task, I assume I need to do something via the command line. This is where I need some help with. How do I deal with these moderation requests that are unable to be reviewed in an admin gui (Postorius/Affinity)? I do recommend removing such choices for Postorius for Member policy. I will be doing this for Affinity until issue 768 is resolved. Thanks! -- Brian Carpenter Harmonylists.com Emwd.com

Hello good people, So today I decided that I should be looking at MM3 to see how far it can take me. I started from the templates and created one for a footer for non-digest messages.

MIMEDefang to fix footers

Does anyone know how to use MIMEDefang to fix the footer as attachment issue when using Mailman3? I've seen several guides/scripts referring to its use with Mailman2, but I'm unsure of how they would match with Mailman 3. Other ways of fixing this issue are also welcome.

digest summary heavily cluttered with hrml code
by Mohsen Masoudfar 11 Nov '20

11 Nov '20

Hi, I am running Mailman 3.1.1 on Ubuntu 18.04. The user complains that the digest summary is cluttered with HTML code. I thought, I may fix it by: Members > {user} > Member options > Delivery mode set to [Plain Text Digest]. After setting the value and clicking [save changes], I tried to check the value by getting back to Members setting for the user, it shows the value as "Regular", which was the value before I tried to update it. Question 1: How may I be sure that the value is set, if it is set? Question 2: How may set it for all members of the list? Question 3: Is there a CLI way to do this? I tried "mailman members " command. But it seems not supporting this option. Any help is much appreciated. Thanks Mohsen

How to Increase outgoing mail volume for Mailman 3
by Brian Carpenter 10 Nov '20

10 Nov '20

Hello everyone, We had a new client come on board that brought a list that had the largest out-going mail volume that I have ever dealt with. So I did what any sane server administrator would do that is running Mailman 3: I ran to Mark Sapiro for help! Here is what the Sage of all things Mailman counseled me to do: 1. Disabled VERP delivery. VERP can help improve mail delivery by delivering 1 message per SMTP transaction (I think I got that right). Using VERP is counter-productive as it can seriously delay outgoing mail delivery for a high-volume list. So you can use something like the following in the MTA section of your mailman.cfg: [mta] verp_confirmations: no verp_personalized_deliveries: no verp_delivery_interval: 0 2. I configured Mailman 3 to run 4 outgoing runners. The default is 1. This action was the game changer. It allows Mailman to handle 4 incoming messages at a time instead of 1. My client's incoming list volume was high enough where it was overwhelming the single outgoing runner. Here is what I added to the mailman.cfg file: [runner.out] instances: 4 Doing this step immediately solved the backlog in var/queue/out. 3. If you start up with a new server for a list that is high volume then keep an eye out for Proofpoint and Vade Security as they will block your new IP address quicker than Mark Sapiro can say "This is a bug. See <some Gitlab.com url>" Mark, thank you! -- Brian Carpenter Harmonylists.com Emwd.com

Digest Formatting
by mailman＠manygoodideas.com 07 Nov '20

07 Nov '20

It appears that a digest is formatted as: list:member:digest:masthead 1. Thread 1 ... N. Thread N foreach thread list:member:digest:header thread list:member:digest:footer A number of my testers are complaining about the formatting: 1) it's hard to visually identify each of the threads (the TOC numbers them, but the numbers aren't shown next to each thread, for example) and 2) it's hard for a novice to know how to reply to a digest thread I'm wondering how other admins have customized their digests to make them more useful. For example, if there was a way in list:member:digest:header to display a link to the archived thread, that would be a good start. list:member:digest:header could emit a horizontal line to separate each thread, but it would be nice to be able to show the number of the thread, etc. Yahoo! Groups used to send out HTML digests that had the thread titles nicely distinguished, live links to the thread, and links to Reply to sender, Reply to All, etc. Thanks for any suggestions!

Member Issue Discovered

Hi Everyone, If I subscribed to a MM3 list with barn(a)emwd.com with the name of Barn Quilter. It shows up in the member roster. So far, so good. I then unsubscribe barn(a)emwd.com. It no longer shows up in the member roster. So far so good. I then resubscribe barn(a)emwd.com with either no name or Barn User and it shows up in the member roster as barn(a)emwd.com with the name of Barn Quilter. Is this a known bug and has been fixed with the latest release? -- Brian Carpenter Harmonylists.com Emwd.com

Subscription issue with ghost confirmations
by Brian Carpenter 01 Nov '20

01 Nov '20

I have a list owner who had his subscription policy set to confirm. Apparently that was too hard for his list members to handle so he changed it to moderate only. If someone sent a subscription request that needed to be confirm, did not respond to it, and then tried subscribing again after the member policy changed to moderate, their 2nd subscription attempt still shows up in the confirmation queue. Is that normal behavior. My understanding is it is. Please let me know if I am wrong here. The real mystery here is when someone tried subscribing again (listname-subscribe@listdomain) hours after the subscription policy was changed to moderate and they still showed up in the confirm queue. How is that possible? I tested the list with two of my addresses and both showed up in the moderation queue as expected. As far as I can tell from the mailman logs, this was the person's first attempt at subscribing. -- Brian Carpenter Harmonylists.com Emwd.com

Internal Server Error on installing Mailman 3 using PIP
by Shashikanth Komandoor 28 Oct '20

28 Oct '20

Dear Mark, As you have suggested in my earlier issue, I have implemented the latest stable version of mailman 3 through the URL https://docs.mailman3.org/en/latest/install/virtualenv.html#virtualenv-inst… . But after the installation through the above URL, when I tried running the command *elinks http://localhost:8000/postorius/lists <http://localhost:8000/postorius/lists>* or *elinks http://localhost:8000/admin <http://localhost:8000/admin>*, I got the error as *Internal Server Error*. I don't find any specific log in mailman.log or in mailmansuite.log. Is there any way to solve this issue ? -- Thanks & Regards, Shashi Kanth.K 9052671936

AttributeError: 'MailingList' object has no attribute 'get_requests_count'
by Shashikanth Komandoor 28 Oct '20

28 Oct '20

Hi Team, I am currently running Mailman 3 with version 3.3.2rc2 and in built postfix version 2.10.1-6 on RHEL 7.5 with PostgreSQL 11.9 version with default values. As of now, we don't have any lists and just installed software components only. After the installation and configuration, I have tried creating the domains and lists. I was successful in creating them but when I tried to login and browse the lists using LDAP authentication, I am getting the "Mailman REST API not available. Restart Mailman core".

Cron error
by gordon＠dickens.com 25 Oct '20

25 Oct '20

I recently upgraded to mailman3 on two Debian servers and I am getting a cron error periodically sent to me as depicted below.

migration from 2.1 - owners and moderators
by Alex Schuilenburg 25 Oct '20

25 Oct '20

We're migrating from 2.1 to 3.2.1 and an odd issue has popped up. It may be something different in the way mailman3 works, or a misconfiguration on my part. Most of the lists migrated so far don't have moderators, just owners. However, when these lists have messages requiring moderation, the owners dont get notified of held messages - unlike 2.1 where they did. Is this a change or is there something I am missing in the configuration? I have the minute/quarterly/hourly etc cron jobs running, although I have had to tune down the frequency of minute to hourly as it takes 6.5 minutes to run* - but I doubt this is the cause. While for the moment I have found the held messages in files in /var/lib/mailman3/messages and figured out which lists are in need of attention (and notified the owners), it seems I may have to do a bit of coding myself to walk through the lists and notify owners when their list is in need of attention. There must surely be something that does this already - or is this moderators only in mailman3? Guidance appreciated. Thanks -- Alex * From the list I realise this is because I am still using the default whoosh backend to haystack and need urgently to switch to xapian or solr, but the info on how to get this working for a noob like me is unfortunately lacking :-(

How to get Hyperkitty to show actual sender e-mail addresses?
by Hans-Martin Mosner 24 Oct '20

24 Oct '20

Hi, I'd like to show actual sender e-mail addresses (basically to block spammers sending to a list that is used as a contact address, so it has no moderation for non-member postings). Hyperkitty just show the display name, which not very informative. Is there a setting to change this behavior? I did not find any using internet search and sifting through the various config files, but I could easily have missed something. Cheers, Hans-Martin

Alias Domains in postfix_domains wrong way around?
by Hans-Martin Mosner 24 Oct '20

24 Oct '20

Hi, we have an "Unusual Postfix configuration" and use "Alias Domains" to work around. However, it looks like "mailman aliases" generates the postfix_domains map the wrong way around, resulting in postfix "Relay access denied" errors for mails received from outside. Didn't notice at first since I tried locally of course. Is my understanding correct that postfix_domains should have the true (externally visible) domains as keys, and values that basically don't matter, or should it have both the real domains and their alias names as keys? With such a convoluted setup, my brain twists a little. For now, I'm listing the real domains explicitly, that seems to work for the local and non-local cases. Cheers, Hans-Martin

Unsubscribe Notifications to List Owners and Members
by Brian Carpenter 22 Oct '20

22 Oct '20

It seems that the only time an unsubscribe notification is sent to a list owner and/or list member is when a list member sends an email to lisname-unsubscribe@listdomain and that list member is not registered with Affinity/Postorius. Can anyone confirm this and if confirmed, is this considered a bug? -- Brian Carpenter Harmonylists.com Emwd.com

Confirm and Moderate Unsubscribe Requests
by Brian Carpenter 22 Oct '20

22 Oct '20

If you set the unsubscription policy to confirm then moderate for a list and someone unsubscribes, they receive a confirmation request. That is good. They respond to it. That is also working fine. However the list owner/moderator than gets a request to approve the unsubscribe request and well, unless I am missing something, I don't see an interface to handles such requests via Postorius. How does one handle an unsubscribe request that requires moderator approval? -- Brian Carpenter Harmonylists.com Emwd.com

debian's 3.2.1 mailman package too unreliable in production - Mail held occasionally causes server errors, and unexplained queue/bad messages -
by Alex Schuilenburg 21 Oct '20

21 Oct '20

We have an issue where a mailing list has had a message sent to it from a non-member, so the message has been held, but when the list owner or I attempt to list the held messages for the list we get a Server Error: "An error occurred while processing your request.". I see the mail being held in the mailman log with the non-subscriber reason, and followed the suggestions in https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… which worked to look at and discard that held message. The problem is, there are more and we have over 900 mailing lists FYI, we are running:Mailman Core VersionGNU Mailman 3.2.1 (La Villa Strangiato)Mailman Core API Version3.0Mailman Core Python Version3.7.3 (default, Jul 25 2020, 13:03:44) [GCC 8.3.0] So we are looking at setting up a virtualenv to run the latest mailman3 3.3.1 as the 3.2.1 package from debian is looking unstable - barely usable. For example, while poking around I found 641 messages in queue/bad , but when I inspect them they look fine. If, as mentioned elsewhere, I rename them to .pck, put them in queue/shunt, and "mailman unshunt" the mail finally gets delivered. Why work now? Some kind of transient bug? Is 3.3.1 the way to go? On that last error, I've now enabled debug and hope to catch why messages are being dropped into queue/bad instead of being delivered. Already I have found errors in the mailman log such as: PermissionError: [Errno 13] Permission denied: '/var/lib/mailman3/queue/out/1603233694.919073+d907eb9512ce11fda515c19d 723537fc4cb15da2.pck'Oct 20 23:41:35 2020 (9793) Skipping and preserving unparseable message: 1603233694.919073+d907eb9512ce11fda515c19d723537fc4cb15da2Oct 20 23:41:35 2020 (9787) Uncaught runner exception: [Errno 13] Permission denied: '/var/lib/mailman3/queue/archive/1603233694.9209244+a0c1f3aab51d3d202aa 37911ab453f094b50b450.pck'Oct 20 23:41:35 2020 (9793) Uncaught runner exception: [Errno 13] Permission denied: '/var/lib/mailman3/queue/out/1603233694.9260252+138142eeb15b16b5da16934 954d1d3aeb1331198.pck'Oct 20 23:41:35 2020 (9793) Traceback (most recent call last): File "/usr/lib/python3/dist- packages/mailman/core/runner.py", line 158, in _one_iteration msg, msgdata = self.switchboard.dequeue(filebase) File "/usr/lib/python3/dist-packages/mailman/core/switchboard.py", line 150, in dequeue with open(filename, 'rb') as fp:PermissionError: [Errno 13] Permission denied: '/var/lib/mailman3/queue/out/1603233694.9260252+138142eeb15b16b5da16934 954d1d3aeb1331198.pck'Oct 20 23:41:35 2020 (9790) Uncaught runner exception: [Errno 13] Permission denied: '/var/lib/mailman3/queue/in/1603233694.9129462+8be9ab12e5dfeab086a1ab8b 3917550aea313505.pck'Oct 20 23:41:35 2020 (9793) Skipping and preserving unparseable message: 1603233694.9260252+138142eeb15b16b5da16934954d1d3aeb1331198Oct 20 23:41:35 2020 (9793) Uncaught runner exception: [Errno 13] Permission denied: '/var/lib/mailman3/queue/out/1603233694.9269004+5f8572edfb07e0e28b9f0b7 928a1184b8c8048ba.pck'Oct 20 23:41:35 2020 (9793) Traceback (most recent call last): File "/usr/lib/python3/dist- packages/mailman/core/runner.py", line 158, in _one_iteration msg, msgdata = self.switchboard.dequeue(filebase) File "/usr/lib/python3/dist-packages/mailman/core/switchboard.py", line 150, in dequeue with open(filename, 'rb') as fp:PermissionError: [Errno 13] Permission denied: '/var/lib/mailman3/queue/out/1603233694.9269004+5f8572edfb07e0e28b9f0b7 928a1184b8c8048ba.pck'Oct 20 23:41:35 2020 (9793) Skipping and preserving unparseable message: 1603233694.9269004+5f8572edfb07e0e28b9f0b7928a1184b8c8048ba The mailman3 user, "list", owns and has full rights all the way down: # ls -ld /var/lib/mailman3/queue/*drwxrwx--- 2 list list 4096 Oct 21 01:45 /var/lib/mailman3/queue/archivedrwxrwx--- 2 list list 77824 Oct 21 00:15 /var/lib/mailman3/queue/baddrwxrwx--- 2 list list 4096 Oct 19 10:44 /var/lib/mailman3/queue/bouncesdrwxrwx--- 2 list list 4096 Oct 5 17:18 /var/lib/mailman3/queue/commanddrwxrwx--- 2 list list 4096 Oct 21 00:00 /var/lib/mailman3/queue/digestdrwxrwx--- 2 list list 4096 Oct 21 00:20 /var/lib/mailman3/queue/indrwxrwx--- 2 list list 4096 Aug 11 18:44 /var/lib/mailman3/queue/nntpdrwxrwx--- 2 list list 4096 Oct 21 01:45 /var/lib/mailman3/queue/outdrwxrwx--- 2 list list 4096 Oct 21 01:45 /var/lib/mailman3/queue/pipelinedrwxrwx--- 2 list list 4096 Aug 11 18:44 /var/lib/mailman3/queue/retrydrwxrwx--- 2 list list 69632 Oct 21 01:45 /var/lib/mailman3/queue/shuntdrwxrwx--- 2 list list 4096 Oct 21 00:20 /var/lib/mailman3/queue/virgin so I'm kinda running out of options why this particular problem is happening.

Wrong info in moderation mail when held due to match of a header rule
by Torge Riedel 18 Oct '20

18 Oct '20

Hi, today I got the first time a moderation mail for a mail which was held due to a match of a header rule: The message is being held because: Header "Yes" matched a header rule At your convenience, visit your dashboard to approve or deny the request. I think this is wrong, it should read 'Header "x-spam" matched a header rule'. Cause the header rule is configured for header "x-spam" and pattern "Yes". I haven't found a bug report for this yet on gitlab. If someone of the developers confirm this is wrong, I will file a bug on gitlab for it. Kind regards Torge

Adding members to a mailman3 mailing list
by Onyeibo Oku 17 Oct '20

Greetings I am testing mailman3 on Fedora Linux (32 and Rawhide). I installed it from the distribution's repositories and I am following the documentation at https://docs.mailman3.org/ I have created a mailing list on my instance but for I am unable to add members to it. Please, consider the following session: COMMAND: sudo -u mailman mailman3 lists OUTPUT: 1 matching mailing lists found: list(a)example.com COMMAND: sudo -u mailman mailman3 members --add members.txt list(a)example.com OUTPUT: usage: mailman members [OPTIONS] LISTSPEC Try 'mailman members -h' for help. Error: Invalid value for '--add' / '-a': Could not open file: members.txt: Permission denied When I try to use '-' instead of passing a file, I find no intuitive way to exit the standard input. What kind of permission is mailman expecting on the input file? I have tried changing ownership to the mailman user -- same output still. How does one use standard input to add members conclusively? Much regards Onyeibo

Hi, How could I save a new style please? I've followed the instructions in https://mailman.readthedocs.io/en/latest/src/mailman/styles/docs/styles.html and after the "manager.register(...)" I typed "commit()". But later, after exiting the mailman shell, the style is not saved... Another question: Where could I find the list of all options, that can be used in a style please? I've found some of them in mailman/styles/default.py (BasicOperation, Bounces, Public, Private, Moderation, etc.), but I'll need some more. TIA for any help, -- Peter

How to prevent members to attach executables (exe, bat, ...) to the emails sent to list

Hi, I am trying to find a way for content filtering to remove executables from the emails sent to the list. I found some hints under: https://mailman.readthedocs.io/en/stable/build/lib/mailman/handlers/docs/fi… but still not clear how to do it for all type of excecutables. Best regards Mohsen

Re: Removing an archive from hyperkitty
by Loïc Dachary 05 Oct '20

Hi, It turns out to be a feature added in 1.3.1 [0]. I wonder if the MySQL instructions listed in this comment[1] are safe to use? I'm reluctant to upgrade because the machine is for production and using packages from Debian GNU/Linux buster is recommended.

Hyperkitty fulltext search performances
by Loïc Dachary 04 Oct '20

04 Oct '20

Hi, I'm in the process of importing a large number of mbox (~30,000) for a few hundred mailing lists. So far around 300,000 mails (~12GB) were imported from two mailing lists. The hyperkitty_import process took ~8 hours and created a 10GB MySQL database. The update_index_one_list for the two lists took a total of ~72 hours and created a ~2GB worth of index in /var/lib/mailman3/web/fulltext_index, which is consistent with the fact that there are lot of attachments (probably 10GB out of 12GB). When I search for one word via the full text search web interface, it takes around 30 seconds to complete (even when repeated twice) and I can see the process grow to use up to 6GB of resident memory. It is running on a recent physical machine with decent IO and a Intel(R) Xeon(R) CPU E5-2609 v2 @ 2.50GHz. Is this consistent with other people experience?

Mailman3 not delivering list mail
by Gordon Dickens 02 Oct '20

02 Oct '20

Hello, I have a fresh mailman3 installation that I recently upgraded from mailman2 on a debian system.Â In any event, I imported some test lists and tested my installation thoroughly and everything seemed to be working fine.Â Then, today, I imported a important live working mailing list from mailman2 and everything appeared to go well both with the import of the list addresses and the archives.Â However, when I sent out the first post on Mailman3 the post was not echoed to the list members.Â Then, I subsequently discovered that the queue had lots of mail undelivered in /var/lib/mailman3/queue/bad. It appears that my mailman3 installation has stopped delivering list mail and that all of the list mail is stuck in /var/lib/mailman3/queue/bad. How do I resolve this situation?Â Can I just remove the files with "rm *" in the /var/lib/mailman3/queue/bad directory?Â Please let me know what I should do to get things working again. Thanks, Gordon

Various patches for mm3 stable 3.3.1
by Ruth Ivimey-Cook 30 Sep '20

30 Sep '20

Folks, For my own purposes I have created some patches which apply to the current mailman pip package. The first of them is for my purposes necessary, and has been discussed here before: being able to specify the address used to listen for tcp connections independently of the address the server considers it to be accessible at. A possible change to this patch would be to check whether this address was undefined but the old hostname was defined, and use that if so. For me this is not needed, and in any case it is a trivial change to make. The second patch adds a bunch of additional logging calls to various network-related parts of the package. I wrote these into the package because I was seeking the cause of template expansion causing messages to be silently dropped. I eventually found the cause was that I had an incorrect setting of the template root URL, but I regard the lack of anything in the logs as just as much of a bug. One important part of those changes was that I added a try/catch around two parts of the 'decorate' code, which is where the silent dropping occurred. If you only take one part of this patch, I encourage you to take this part. For the third patch, I discovered that the task runner was at one point busy-waiting to the tune of 100% cpu, and the cause was the way that the runner checked to see if there was work left in the queue. I am not quite sure what was the exact problem, but I think it was that there was something to do, but it was not achievable at that time, and the result was continual retry. The third patch changes the logic slightly so that this no longer occurs - retry will happen, but somewhat more gracefully. I hope you find some use in these three. Finally, I am currently experiencing problems with templates and would appreciate any thoughts: 1. If I do not set up 'individual' or 'full' personalisation, all is well and the default footer templates are expanded as expected. However setting up personalisation causes template expansion to fail completely, and messages get sent with a blank expansion. 2. I would find the postorius UI much easier to cope with if the default template was 'populated' into the UI wherever it was non-blank, rather than the UI starting off as if no templates were defined at all. Regards, Ruth

Unable to remove non-member
by Brian Carpenter 29 Sep '20

Hi Everyone, I ran across a strange issue today. A client reported the inability to remove a non-member in the following format: z_email/domain.org.za(a)domain.org.za The reported error from Postorius was: "The user could not be removed" I used https://verifalia.com/validate-email to validate the email address and it is syntactically correct. -- Brian Carpenter Harmonylists.com Emwd.com

Discard all mail with the subject "The resutls of your email commands"
by w.schoener＠alp.dillingen.de 29 Sep '20

29 Sep '20

Hello, I am using mailman 3.2.1 for several mailing lists. My colleagues want me to stop all mails with the subject "The results of your email commands". I found some contributions here, but nowhere a solution for this question. Does anybody has any suggestion? Maybe I could try to handle this outside of mailman, but then I would have to pass this task on to someone I dont know .... :-( Thanks for all hints. :-) Wolfgang

New releases
by Abhilash Raj 25 Sep '20

25 Sep '20

Hi Everyone, I am pleased to announce new stable releases for: - Postorius: 1.3.3 Changelog: https://docs.mailman3.org/projects/postorius/en/latest/news.html#id1 Download: https://pypi.org/project/postorius/1.3.3/ - Hyperkitty: 1.3.3 Changelog: https://hyperkitty.readthedocs.io/en/latest/news.html#id1 Download: https://pypi.org/project/HyperKitty/1.3.3rc1/ - Mailmanclient: 3.3.1 Changelog: https://docs.mailman3.org/projects/mailmanclient/en/latest/src/mailmanclien… Download: https://pypi.org/project/mailmanclient/3.3.1/ - Django-mailman3: 1.3.3 Changelog: https://gitlab.com/mailman/django-mailman3/-/blob/master/README.rst Download: https://pypi.org/project/django-mailman3/1.3.3 Python 3.6+ and Django 2.0+ is supported for all of them. Django 3.0 support for Hyperkitty requires manually upgrading a dependency (django-haystack>=3.0b2, once a stable version of this has been released, it shouldn't require manually upgrading). There are tons of bug-fixes across the board and some new features. Biggest visible change is switch to Bootstrap 4, which has been long pending for us. Bootstrap 4 completely changes the CSS grid model using the new Flexbox. There might be some small changes or breakages when using on mobile. Please report such issues to us via Gitlab! Some other notable changes are in Postorius, which includes many more list settings exposed include content filtering settings, bounce processing (which was added in the previous release of Mailman Core) settings and some other ones. Settings page is also slightly different with all the sections on the vertical menu on left instead of horizontal tabs. You can now also specify a reason when rejecting held messages. There was also a gnarly bug, which caused the name of some members to be the string "None". For the longest time, I couldn't figure out the reason for it, but it ended up being a simple fix in mailmanclient's json serialization of display_name, which would result in Python's None value being passed as string "None" to Mailman's API for subscription. There is also better support for filtering visible lists based on the current vhost, which I see a few people are already waiting for from mailman-users list. A full changelog has been added to each project in the top. -- thanks, Abhilash Raj (maxking)

My Server is unable to connect to Mailman REST API few times
by Shashikanth Komandoor 24 Sep '20

24 Sep '20

Hi Team, I am currently running Mailman 3 with version 3.3.1 and in built postfix version 2.10.1-6 on RHEL 7.5 with PostgreSQL 11.7 version with default values in production environment from the past 4 months almost. As of now, we are having around 1327 lists created on this. When I am trying to do some operations like creating the lists, deleting the lists or accessing the lists through the GUI, I am getting the below error. If I am trying to do the operations through API or through mailman shell, still I am not able to connect to the API. Something went wrong Mailman REST API not available. Please start Mailman core. But my mailman core was working fine in the background. At the same time I was able to do other operations on a few other lists. By the time I am getting the above error, the mailman.log recorded the below messages. *[2020-09-16 12:49:08 +0530] [2600] [CRITICAL] WORKER TIMEOUT (pid:20234)* *[2020-09-16 12:49:08 +0530] [20234] [INFO] Worker exiting (pid: 20234)* *[2020-09-16 12:49:09 +0530] [21042] [INFO] Booting worker with pid: 21042* My mailman.cfg configuration is as below. The timeout value is the default value. I did not set any customized value. *(venv3) [root@lsmgr mailman]# grep -v ^# /var/lib/mailman/mailman/var/etc/mailman.cfg* *[archiver.hyperkitty]* *class: mailman_hyperkitty.Archiver* *enable: yes* *configuration: /var/lib/mailman/mailman-hyperkitty/mailman-hyperkitty.cfg* *[mta]* *incoming: mailman.mta.postfix.LMTP* *outgoing: mailman.mta.deliver.deliver* *lmtp_host: 0.0.0.0* *lmtp_port: 8024* *smtp_host: localhost* *smtp_port: 25* *[webservice]* *workers: 10* *[database]* *class: mailman.database.postgresql.PostgreSQLDatabase* *url: postgres://<postgresdbuser>:<postgresdbpassword>@127.0.0.1/mailman <http://127.0.0.1/mailman>* Then as per the suggestion I got earlier I configured the [webservice] section in the above file as below. *[webservice]* *configuration: /var/lib/mailman/mailman/var/etc/gunicorn.cfg* * [root@lsmgr logs]# cat /var/lib/mailman/mailman/var/etc/gunicorn.cfg* *[gunicorn]* *workers = 10* *timeout = 90 * After the above configuration, I found many errors like below in mailman.log file: *sqlalchemy.exc.NoSuchColumnError: "Could not locate column in row for column 'pended.id <http://pended.id>'"* *sqlalchemy.exc.ResourceClosedError: This result object does not return rows. It has been closed automatically.* *sqlalchemy.exc.DatabaseError: (psycopg2.DatabaseError) error with status PGRES_TUPLES_OK and no message from the libpq* The above might be few of the errors. FYI, for the creation of each list, it is taking almost around 15 to 20 minutes. After multiple times of the above error messages, at some time, I am fortunately getting the list created or some other operation getting done. I found the same scenario when the workers are from default 2 to 10. I don't understand where exactly I need to focus to solve the issue. Please let me know if I have to share any other details for you to suggest to me. -- Thanks & Regards, Shashi Kanth.K 9052671936 <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Missing whitespace in postfix_vmap after mailman genaliases

I solved the problem by adding a whitespace in the last line and I made a new postmap for postfix_vmap. But it would be better to solve the problem by changing the genaliases process in the next update. Regards Wolfgang

Mails are not archived at all -- how to check if Hyperkitty is running or not?
by Franklin Weng 23 Sep '20

23 Sep '20

Hi, I set up the mailman3 services and lists, and we can send mail to the list successfully. However in the Archive section I couldn't see anything and all the lists were "inactive" and hence were hidden by default. I confirmed that api_key set in the /etc/mailman3/mailman-hyperkitty.cfg and /etc/mailman3/mailman-web.py is the same. I also confirmed that the apache2 wsgi module has been loaded. In the mailman.cfg database is set to mysql and in the mailman-web.py database is set to sqlite3. Does it matter? I tried to search but couldn't find any further information or discussion about this. There is no systemd service for Hyperkitty. How can I check if Hyperkitty is running or not? Thanks, Franklin

API timeout for one list

Hi, I am trying to find how I may change this. I have an attachment of 800 KB, and when I post it to the list, I do not get any response and nothing is hold. It looks like the message is just dropped.

Problem with list creation
by Pawel Grzywaczewski 22 Sep '20

22 Sep '20

Hi, We want to create thousand of lists. We use a simple curl command curl --user restadmin:restpass -X POST http://localhost:8001/3.1/lists -d fqdn_listname=nameOfTheList(a)example.com After creating ~2k of them we started getting errors in Mailman logs: ``` [2020-09-16 17:11:10 +0200] [4564] [DEBUG] POST /3.1/lists [2020-09-16 17:11:41 +0200] [1339] [CRITICAL] WORKER TIMEOUT (pid:4564) [2020-09-16 17:11:41 +0200] [4564] [INFO] Worker exiting (pid: 4564) [2020-09-16 17:11:41 +0200] [5019] [INFO] Booting worker with pid: 5019 ``` Since then creation fails in most cases. We increased timeout in mailman.cfg ``` [gunicorn] workers: 4 timeout: 900 ``` And we increased timeout in nginx ``` http { # MODIF UNICORN proxy_connect_timeout 300s; proxy_read_timeout 300s; # MODIF UNICORN ``` Where might be the problem? How to start investigating and fix it? Thanks, Paweł

cc'd e-mail addresses rewritten with @invalid.domain
by peterbw＠gmail.com 22 Sep '20

22 Sep '20

Hi, We've recently noticed an issue where users who are cc'd in a message where a mailing list is also within the cc list are getting rewritten a user(a)invalid.domain. This issue looks like it may be related to Outlook and how user names are displayed specifically. Here is an example: To: test_user(a)gmail.com cc: listserv(a)lists.test.org; Williams, Peter; "Williams, Peter" maps to a user e-mail in the Outlook Global Address book. When the message is sent the list will send the message with the first name and last name separated, for example the message will appear: to: test_user(a)gmail.com cc: listserv(a)lists.test.org, Williams(a)invalid.domain, Peter(a)invalid.domain This only seems to happen with users who are cc'd who are also members of the list that is being cc'd. For example in the scenario above my e-mail that is cc'd is also a member of listserv(a)lists.test.org. This issue does not occur if the user e-mail address is listed before the mailing list in the cc field. So for example, if the cc in the scenario above contained Williams, Peter; listserv(a)lists.test.org; it would route properly. Do you know what may be causing this? Please let me know if there is any additional information I may provide regarding this and I will try to respond as soon as possible. Thanks and have a nice day! Peter

Template path
by Seth Seeger 21 Sep '20

21 Sep '20

Hello everyone, I’m running Mailman from Docker containers, without much customization. (Postorius 1.3.3, Core 3.3.1, API 3.1, Python 3.8.5). I’ve created a list:user:notice:welcome template, and when I try to confirm a subscription, I get an error. I followed previous emails on this list which told me to set POSTORIUS_TEMPLATE_BASE_URL in /opt/mailman/web/settings_local.py, but that doesn’t seem to make any difference. (I set it to a different value and the error message didn’t change. I also tried setting it in /opt/mailman/core/settings_local.py to no effect. After each change, I restarted mailman-web and mailman-core containers.) From within mailman-web and mailman-core containers, I can reach “mailman-web:8000”. In the webpage, I see: Mailman REST API not available. Please start Mailman core. In /opt/mailman/core/var/logs/mailman.log, I get: [17/Sep/2020:16:23:29 +0000] "GET /3.1/lists/xxx.example.com HTTP/1.1" 200 416 "-" "GNU Mailman REST client v3.3.1" Sep 17 16:23:35 2020 (48) deque: Traceback (most recent call last): File "/usr/lib/python3.8/site-packages/urllib3/connectionpool.py", line 426, in _make_request six.raise_from(e, None) File "<string>", line 3, in raise_from File "/usr/lib/python3.8/site-packages/urllib3/connectionpool.py", line 421, in _make_request httplib_response = conn.getresponse() File "/usr/lib/python3.8/http/client.py", line 1347, in getresponse response.begin() File "/usr/lib/python3.8/http/client.py", line 307, in begin version, status, reason = self._read_status() File "/usr/lib/python3.8/http/client.py", line 268, in _read_status line = str(self.fp.readline(_MAXLINE + 1), "iso-8859-1") File "/usr/lib/python3.8/socket.py", line 669, in readinto return self._sock.recv_into(b) socket.timeout: timed out During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3.8/site-packages/requests/adapters.py", line 439, in send resp = conn.urlopen( File "/usr/lib/python3.8/site-packages/urllib3/connectionpool.py", line 724, in urlopen retries = retries.increment( File "/usr/lib/python3.8/site-packages/urllib3/util/retry.py", line 403, in increment raise six.reraise(type(error), error, _stacktrace) File "/usr/lib/python3.8/site-packages/urllib3/packages/six.py", line 735, in reraise raise value File "/usr/lib/python3.8/site-packages/urllib3/connectionpool.py", line 670, in urlopen httplib_response = self._make_request( File "/usr/lib/python3.8/site-packages/urllib3/connectionpool.py", line 428, in _make_request self._raise_timeout(err=e, url=url, timeout_value=read_timeout) File "/usr/lib/python3.8/site-packages/urllib3/connectionpool.py", line 335, in _raise_timeout raise ReadTimeoutError( urllib3.exceptions.ReadTimeoutError: HTTPConnectionPool(host='mailman-web', port=8000): Read timed out.

Redundant and load balanced Mailman3
by Pawel Grzywaczewski 20 Sep '20

20 Sep '20

Hi, Can someone share some hints about how to deploy redundant and load balanced Mailman3? What are your recommendations and best practices? For example what components to put on the same VM? Can we have 2VM with Mailman core/Postorious/Hyperkitty/django-mailman/mailmanclient connecting to one (the same) database? How to load balance mail routing (incoming)? Thanks! Paweł

Hi everyone, if I write a my lists from other email address I get the correct message: opendkim[23516]: 8EEE440FFD: DKIM-Signature field added (s=mailselector, d=catania.linux.it). While if I write to a my lists from email address Gmail, on opendkim I get the following messages: opendkim[23516]: BA95241952: no signing table match for 'maszap69(a)gmail.com' opendkim[23516]: BA95241952: s=20161025 d=gmail.com SSL error:04091068:rsa routines:int_rsa_verify:bad signature opendkim[23516]: BA95241952: bad signature data The message is received regularly by all members of the list. I also receive an email at superuser: [Django] ERROR (EXTERNAL IP): Internal Server Error: /hyperkitty/api/mailman/archive Internal Server Error: /hyperkitty/api/mailman/archive OperationalError at /hyperkitty/api/mailman/archive (1366, "Incorrect string value: '\\xF0\\x9F\\x98\\xB1\\xF0\\x9F...' for column `mailman3web`.`hyperkitty_email`.`content` at row 1") ... If I check with mail-tester I get 10/10 If I check with dmarcanalyzer I get "This seems to be a valid DKIM Record." I don't understand where the problem is. Could anyone tell me how to solve? Thank you in advance Max

Can creating too many Django accounts crash Mailman3 server?
by Mohsen Masoudfar 19 Sep '20

19 Sep '20

Hi, It seems anybody can go to the site: https://LISTSERVNAME/mailman3/postorius/lists/ and click on the [Sign up] on the top-right corner and create an account. This can easily be automated, even though the next step, confirming the email address, being ignored. I believe it can be used as a target for a DOS attack by creating so many accounts, that eventually causes an 'out of space' error. Is this a justified concern? Is there a way to manage this feature in a secure way?

Note2: Posting messages from my personal Gmail account or cmdline mail program to the same test list will also deliver as expected. ________________________ Bryan Loniewski Rutgers University OIT:EAS:Messaging and Collaboration Services System Administrator

Re-send subscription response and file permission error in queue
by accounts-mailman＠holbrook.no 15 Sep '20

15 Sep '20

A user sent subscription request to the `..-join@` address of a list. Email domain wasn't set up properly, so response got rejected. Now, if the user tries to send another request, no reponse comes back. In the log I find a python stack trace saying subscription already pending. ``` Sep 08 10:32:44 2020 (19918) Traceback (most recent call last): File "/usr/lib/python3/dist-packages/mailman/core/runner.py", line 171, in _one_iteration self._process_one_file(msg, msgdata) File "/usr/lib/python3/dist-packages/mailman/core/runner.py", line 264, in _process_one_file keepqueued = self._dispose(mlist, msg, msgdata) File "/usr/lib/python3/dist-packages/mailman/runners/command.py", line 196, in _dispose mlist, msg, msgdata, parts, results) File "/usr/lib/python3/dist-packages/mailman/commands/eml_membership.py", line 104, in process ISubscriptionManager(mlist).register(subscriber) File "/usr/lib/python3/dist-packages/mailman/app/subscriptions.py", line 520, in register list(workflow) File "/usr/lib/python3/dist-packages/mailman/app/workflow.py", line 69, in __next__ return step() File "/usr/lib/python3/dist-packages/mailman/app/subscriptions.py", line 227, in _step_sanity_checks raise SubscriptionPendingError(self.mlist, self.address.email) mailman.interfaces.subscriptions.SubscriptionPendingError ``` Furthermore I am getting a permission denied error in the attempt of shunting the message, which I don't quite understand because the folder has user `list` group `list` and `700` mode: ``` Sep 08 10:25:29 2020 (19918) SHUNTING: 1599553529.9889646+88be5afa0bf3111a83e68cc97ce2000723ad93fd Sep 08 10:29:49 2020 (19918) Uncaught runner exception: [Errno 13] Permission denied: '/var/lib/mailman3/queue/command/1599553789.306307+6fee74af69263553b5ffd0e73cc095ab651bd855.pck' Sep 08 10:29:49 2020 (19918) Traceback (most recent call last): File "/usr/lib/python3/dist-packages/mailman/core/runner.py", line 156, in _one_iteration msg, msgdata = self.switchboard.dequeue(filebase) File "/usr/lib/python3/dist-packages/mailman/core/switchboard.py", line 150, in dequeue with open(filename, 'rb') as fp: PermissionError: [Errno 13] Permission denied: '/var/lib/mailman3/queue/command/1599553789.306307+6fee74af69263553b5ffd0e73cc095ab651bd855.pck' ``` How can I remove the pending subscription, or re-send the response email?

Held Message view, JSONDecodeError: Invalid control character

I am running the Debian 10 mailman3 and mailman3-web packages with mariadb. I received an email to the list from an invoicing software and now I am unable to view or accept this email from the list. All other lists seem to be still working fine. I'm guessing there is a piece of data in my database that is corrupt or unable to be decoded, but I am at a loss on how to find and fix it.

Mailman3 throws 500 error (unicode encode) when loading held messages in Postorius
by Simon Handfield 14 Sep '20

14 Sep '20

Hi, I have been working through other threads that indicate the same symptom (500 error when loading held_messages for a list). These include potential truncation of values in pendedkeyvalue table (don't this is our problem) and error when trying to access a message in /var/lib/mailman3/messages (ran the suggested code to loop through the stored files but no error was thrown.)

How to set the original sender to the Reply-To?
by Marcel Pietschmann 12 Sep '20

12 Sep '20

Hi everybody, I have a settings problem. Mailman adds the original sender to the Reply-To or Cc in the case where there's a reply to setting in force on the list. In my case, mailman sets the sender always to Cc. How can i change it? Greets Marcel My settings: Personalize = None Anonymous list = No Reply to list = No Munging DMARC = Munge the From: header with list adress
