I think this is mostly because the configuration parser doesn't understand the in-line comments. So, if you are using the configuration exactly as it is mentioned in the documentation, it could be the cause of this problem. Solution to that would be to just remove all the in-line comments. [mta] incoming: mailman.mta.postfix.LMTP outgoing: mailman.mta.deliver.deliver lmtp_host: 172.19.199.2 # IP Address of mailman-core container lmtp_port: 8024 smtp_host: 172.19.199.1 # IP Address of host where postfix is. smtp_port: 25 configuration: /etc/postfix-mailman.cfg Like the two comments seen in the configuration above. I will update the documentation too so that others don't get caught in something like this. Thanks! -- thanks, Abhilash Raj

postfix, dovecot and MM3
by Matt Richards July 15, 2017

July 15, 2017

This is a bit of a lengthy post, but I wanted to make sure I had enough detail to document the problem I'm experiencing. The quick summary is, I'm having a problem with postfix, dovecot and mailman3.. routing Problem: Postfix mail routing is mostly working correctly with the execpetion of handling test-confirm+157fcaf78907a2bbf21b36aaf349386e09e801a8(a)example.com emails. As you can see below in my postfix config, I have defined recipient_delimiter.. I'm not sure what else is going wrong.. For example, if I email test-confirm(a)example.com, the mail will route over to MM correctly as postfix is able to find this exact email address in the postfix_lmtp transport file. However, if I reply to a mm confirmaion email, test-confirm+157fcaf78907a2bbf21b36aaf349386e09e801a8(a)example.com, postfix will fail to deliver the email correctly due postfix trying to lookup the test-confirm(a)example.com in dovcot's virtual mailbox tables. I hope this is enough information... My research seems to indicate I might need to change something with virtual_alias_maps, however from my testing, changing this setting to include MM3's geneated postfix_lmtp file, it'll cause more problems.. I've also considered using a sub-domain, for example lists.example.com instead of my primary domain for mm3, this may fix a lot of my issues. Setup overview: Integrated mailcow-dockerized (https://github.com/andryyy/mailcow-dockerized) & docker-mailman (https://github.com/maxking/docker-mailman) - all I have done is merged the containers from the docker-mailman docker-compose.yml into mailcow's docker-compose.yml - updated the network settings for docker-mailman to use mailcow's internal network if needed, I can provide my docker-compose file. mx1.example.com = An internal eMail firewall and security server Below is the reject log from postfix: Jul 15 18:11:22 mx10 postfix/smtpd[418]: NOQUEUE: reject: RCPT from

Does hyperkitty show JPEGs in line and what about attachments?
by Jason Glazer July 13, 2017

July 13, 2017

I run several MailMan 2.1 mailing lists and some subscribers are frustrated by the way pipermail deals with JPEGs that are embedded in the messages and also with how attachments are handled. Does hyperkitty in Mailman 3.1 do better on these issues. Assuming this message gets archived, I am going to try embedding a small picture right here: Hopefully that shows up in the archive. I won't add an attachment because the list may not allow it but I'm curious how those are handled.

Docker Mailman3 installation frustration
by ccsmith＠cetsi.com July 13, 2017

July 13, 2017

I've been working on installing Mailman3 for several weeks now, with limited success. I have tried various installation methods following instructions on numerous different web pages. My experience has been that the instructions are often conflicting and never complete. My best success has been with the Docker version, so that's what I'm going to concentrate on here. I'm running Ubuntu 16.04 (under Citrix XenServer), with Apache httpd and postfix. Following the instructions on https://asynchronous.in/docker-mailman/, I did the following: * created the directories "/opt/mailman/core" and "/opt/mailman/web", * created "/opt/mailman/core/mailman-extra.cfg" and inserted the suggested [mta] directives, * inserted the "transport_maps", "local-recipient_maps", and "relay_domains" entries in the /etc/postfix/main.cf file, * created the necessary apache config files, * cloned "https://github.com/maxking/docker-mailman", * ran "docker-compose up -d" At this point, I am able to connect with Postorius. All of the text and icons show up properly; all is well. It tells me (correctly) that "There are currently no mailing lists." When I click on the "Login" link at the top right, the "Sign In" page displays correctly. (Aside: Why do so many apps/sites have difficulty with choosing between "login" and "sign in" and, in fact, use both terms? It can really be off-putting to non-tech users... and me.) If I input an incorrect login, I receive (correctly) the message "The username and/or password you specified are not correct." However, if I input the correct sign-in, I receive: "Server Error (500)". Running "sudo docker exec -it mailman-web cat ../mailman-web-data/logs/mailmanweb.log" shows me: ERROR 2017-07-12 20:34:25,073 25 django.request Internal Server Error: /accounts/login/ Traceback (most recent call last): File "/usr/local/lib/python2.7/site-packages/django/core/handlers/exception.py", line 39, in inner response = get_response(request) ... more stuff ...

Confirm on mass subscription
by David Krantz July 7, 2017

July 7, 2017

Hi, Is there a way of requiring all mass subscribed users to confirm their email adress? I have an use case where we have a current mail list but when moving it to mailman I for different reasons would like to confirm all subscribers. Some very shallow testing suggests that if I just add them using mass subscribe, they will not have to confirm at all. I have yet to upgrade to 3.1 but I will do so in due time. cheers // David

Changing display name with "mailman withlist"
by Mark Ziranski July 5, 2017

July 5, 2017

Hello, I am looking for a way to change the display name of a mailing list on command line. As written in "mailman withlist --details" I have created a script named "change.py". When executing the script as written in the manual, I get the following error: (venv-3.5) [root@localhost mailman]# mailman withlist -r change example(a)example.org 'new display name' usage: mailman [-h] [-v] [-C CONFIG] {help,aliases,conf,create,digests,import21,info,inject,lists,members,qfile,remove,reopen,restart,shell,start,status,stop,unshunt,version,withlist} ... mailman: error: unrecognized arguments: new display name According to the manual it should be possible to pass arguments in withlist: mailman withlist [options] listname [args ...] while " mailman withlist -h" says: usage: mailman withlist [-h] [-i] [-r RUN] [--details] [LISTNAME] Mailman version: GNU Mailman 3.2.0a1 (La Villa Strangiato) Btw. I know that there is an interactive shell to execute the script but I need a solution that can be run in a shell script. Thank you.

Problem with docker and css
by Alexander Klotz July 5, 2017

July 5, 2017

Hi everyone, we are experiencing some issues trying to run mailman3 on our server. First, when starting docker-compose up -d the mailman-web container is not started. The log shows: mailman-web | useradd: user 'mailman' already exists If we start the container with docker-compose up (without -d), all containers start accurately. Are there other files integrated / processed when starting docker-compose up with -d? Secondly, no css and javascript-elements, as well as images are embedded in the web surface. In the mailman-web log we can see they aren't found (Error 404), but trying with docker-compose exec -T mailman-web ls /opt/mailman-.../static/.../... they actually can be found. Can anybody tell me why these problems appear and how to solve them? Any help would be highly appreciated. Thanks & Regards, Alex Klotz (culturebase editorial staff)

REST API notes
by tlhackque＠yahoo.com June 29, 2017

June 29, 2017

As a beginner with the REST API, I found it necessary to read code and experiment to figure out how to get things done. There are a number of implementation choices that are unusual. There is some documentation in src/mailman/rest/docs. It's oriented toward Python and intermixes the mailman client & REST API, apparently trying to show equivalence. Here are some notes that may help others to avoid repeating my research. They reflect Mailman 3.1. Some reflect issues that I've opened, but I think it's worth knowing how things work today. I attempted to tie together some of pieces that are in the documentation - and note some things that aren't. I may have some things wrong, but this reflects my current understanding. (And client code.) The REST API has a hybrid interface: Requests are made with application/x-www-form-urlencoded POST, PUT, PATCH and delete http requests. Requests are also accepted as parameter strings. The responses are JSON. (This is rather surprising - one would expect JSON requests - and I hope someday they'll be accepted, as the split complicates clients. I suspect this evolved to simplify the initial Web GUI client (Postorious), but it precludes using standard JSON-in/JSON-out client libraries.) Error responses are often misidentified as content-type: application/json, but actually contain a text/plain error message. This isn't universally true; for example the 401 response actually IS JSON. A client has to guess and handle decoding exceptions. The API presents resources hierarchically, rooted at '/'. The top level resources include /users, /lists. /addresses, /domains, /system The next level is a resource id. There is a an id which is stable for the lifetime of an object, and a current name (which can be changed). For example, a list has a name like mylist(a)example.com, and a list_id of mylist.example.com. But if you change the list name, it becomes mynewname(a)example.net, while the list_id remains mylist.example.com. Lists are associated with "domains", which are the "domain part" of the list's address. That is, the part after the @. This is sometimes referred to as the "mail host", but there need not be a real host. Just something on the left side of a DNS MX record. Also, don't confuse the use of "mail host" with that of "SMTP Server", which is how Mailman sends mail. The domain is where Mailman expects to receive it. A fully qualified list name is the list name + domain - e.g. its posting address. One domain can (and usually does) support more than one list. If you delete the domain, all its lists go away too. A domain has to be created before you can create a list with an address in that domain. Resources are created with a POST to their top-level resource. To create a domain, post to /domains with mail_host => the domain, and (optionally) description => a description for the GUI. The response isn't JSON as one would expect. In fact, it's an empty application/json response with a 201 status. To create a list, one POSTs to /lists. This post takes a restricted set of parameters; in the case of a list, just its fqdn_listname, (and an optional style - which isn't well defined). The response isn't JSON as one would expect. The Location header of the response contains a URL of the new list. To configure the list, you have to follow up with a PUT or PATCH to that URL + /config This is where you can set the description, posting policy, etc. It's unrealistic to do a PUT; even if you're cloning another list, there's no programatic way to determine which attributes are writable. PATCH what you know... Members are associated with e-mail addresses - which belong to Users. You create a user by posting to /users with email => the email address, and optionally display_name => the name string. (A user can also be implicitly created by subscribing an e-mail address, but that gets confusing.) The e-mail address is the primary email address for the user. More later. Again, you get a Location header in the response, which you can use to PATCH /preferences to set delivery_status, etc. .These preferences are part of a hierarchy - many have a system default, a list default, the user default, and a subscription to that list value. You can find the User associated with a list by a GET of /addresses/address(a)example.net. This GET returns two URLs: user => the user owning this address, and self_link => the address object. Note also that there are both an email and original_email attribute. The latter preserves case. The former is used internally by Mailman as a resource key, etc. (Though exactly what happens if John(a)example.net and john(a)example.net both subscribe is unclear.) Once a list is configured, you can add members. This requires the list_id - which you don't (officially) have. So you do a GET on the list resource, to get the list_id. Then you can subscribe a member with list_id => (the list id), subscriber => email address. Optionally you can pre_verify/confirm/approve the member and/or add a display_name.. POST to /members. Again, you get a Location header back. You can't specify everything you might like. as a creation attribute. So you may have to PATCH the member to, for example, set the moderation_status. You may also need to PATCH the member /preferences if you want to set list-level delivery status, etc. Consider adding at least an owner when creating a list. One challenge is that almost everything requires multiple REST operations to set up. But REST (by definition) is stateless. So the best you can do is order operations & hope. The mailman client examples refer to transactions (e.g in users.rst, there is 'transaction.commit(); - but REST can't hold state. It does appear that the server uses DB transactions to ensure that any given REST operation is ACID, but the composite operations (e.g. create a list and set it's config) can not be Atomic. This is an architectural flaw in the API. Symbolic names (which are required) for attributes are in the src/mailman/interfaces/(class).py. What you can get/set comes from src/mailman/rest/(class).py.

Some doc updates from Fedora install experience

Trying to get mailman3 setup round three. Some notes from a first timer that I hope will be of use. These are in order of experience, and unfiltered. I'm a bit confused about why you have a release that pip should be able to install, but the advice I get is to pretend I'm developing from git. But off we go: Following http://docs.mailman3.org/en/latest/devsetup.html: I'm using Fedora 25. Packaged Python is 2.7.13-2, 3.6.3-6, 2-setuptools 25.1.1-1, 2-virtualenv 15.0.3-2 nodejs-less 2.7.1-1 sassc 3.4.1-1 a) fedora now uses dnf rather than yum (and has for some time). Specify dnf install rather than yum install b) sassc is packaged - just add it to the end of the dnf install string. I'm using sendmail. Directly outbound. Inbound, a custom LMTP client. It is possible to setup sendmail to use LMTP for local delivery - but if you do, it's the ONLY local delivery (or you're into some serious sendmail configuration hacking). Most installations use procmail and/or pipes. I could probably extract a pipe -> lmtp script from my project - but it's Perl, not Python. The current install process assumes a lot of Python knowledge/interaction, which is a barrier to adoption. Documentation should note that the virtualenv commands create directories of those names (I'm not a Python person, so everything is a surprise.) To save typing, I defined: alias p0='[ -n "$_OLD_VIRTUAL_PATH" ] && deactivate;cd ~mailman3' alias p2='[ -n "$_OLD_VIRTUAL_PATH" ] && deactivate;cd ~/mailman3 && source venv-2.7/bin/activate' alias p3='[ -n "$_OLD_VIRTUAL_PATH" ] && deactivate;cd ~/mailman3 && source venv-3.5/bin/activate' I suggest using mailman3 as the top level in your examples, since there's also a mailman directory in the path, and mailman is easily confused with mailman/mailman Also, if you have mailman2 - or your distro has provision for it - 'mailman' has other semantics. (Including, but not limited to things like SeLinux contexts...) I got tracebacks when I got to the "mailman info" command. After some experimentation/digging, resolved with dnf install python3-dateutil This was confusing because Python/pip seemed to think dateutil was installed - perhaps it fell back to the Python2 version? mailman info works! >> You can edit your mailman.cfg file But which one? there's one in src/mailman/config and one in var/etc/mailman.cfg. Should specify. But var looks like the one to modify, the other. The suggestion to look at the one in src for doc isn't very helpful, there are virtually no comments. So, look at the schema. To get started, I set the following: [mailman] site_owner: admin(a)example.net [devmode] enabled: yes [mta] smtp_host: smtp.example.net smtp_port: 587 #smtp_user: #smtp_pass: lmtp_host: 192.168.148.19 lmtp_port: 8024 ### Note: LMTP needs security, preferably SSL.. Thiis is probably a bunch of config items that get fed into the Python library (e.g. use ssl, cert files (current openssl includes key w/cert, but often multiple certs - rsa + ecdsa) verify client, ca bundle, ca path, client ca.) Despite the list, these are all pass-through parameters, so should not be much work. Once you have SSL, a simple shared secret (e.g. password) can be used. Or (my preference) client verification (certificate). Maybe a proxy, but who needs another process to manage? FWIW, my MTA runs on a separate VM from the MM instance, so assuming "localhost" is secure doesn't work. It also doesn't work on a multiuser machine. mailman start got some things running. Telnet & LHLO wakes up LMTP! I guess I should try to setup my first list. More as it develops.
