Splitting hosts: mta&core vs postorius
by Ruth Ivimey-Cook 18 Jan '24

18 Jan '24

I'm trying to set up mailman3 on two hosts, one of which runs core + exim, the other runs postorius (&possibly hyperkitty). I have I think got core set up correctly, and postorius is sort of usable, but anything in the web ui that talks to core ends up with a white screen. I think what is happening is a postorius URL ends up with the core (or perhaps no) hostname, and as there's nothing there to answer it fails. I've checked the settings and I don't think I have misconfigured postorius. Is it possible that the bad url is being passed from core to postorius in some way and reused without changing the host? In the config at present, both hosts are visible to the browser, and each host can communicate with the other. Any ideas on how to pin down the problem better? Ruth

how to migrate mailing lists to a new domain using mailman 3
by C. Souza 18 Jan '24

18 Jan '24

In a few days my current domain will be disabled (it is out of my control) and I would like to know how to migrate the mailing lists to the new domain name. As a solution I added a new domain in mailman 3 and created a script that replicates the lists in this new domain. To forward the emails received by the old lists, the script removes the members and adds the email of the new list. Is there a fashionable way to do that? Also, one problem that I don't have a solution is the archive of the old lists. How to bring them to the new ones? Thanks for your help. My mailing list server is running on a CenOS-7x with postgreSQL and the following mailman packages: Package Version ------------------- ---------- 1 aiosmtpd 1.2.4 2 alembic 1.5.3 3 arrow 0.17.0 4 asgiref 3.3.1 5 atpublic 2.1.2 6 authheaders 0.13.0 7 authres 1.2.0 8 bleach 3.3.0 9 blessed 1.17.12 10 certifi 2020.12.5 11 cffi 1.14.4 12 chardet 4.0.0 13 click 7.1.2 14 cmarkgfm 0.5.2 15 cryptography 3.3.1 16 decorator 4.4.2 17 defusedxml 0.6.0 18 Django 3.0.12 19 django-allauth 0.44.0 20 django-appconf 1.0.4 21 django-compressor 2.4 22 django-extensions 3.1.0 23 django-gravatar2 1.4.4 24 django-haystack 3.0 25 django-mailman3 1.3.5 26 django-picklefield 3.0.1 27 django-q 1.3.4 28 djangorestframework 3.12.2 29 dkimpy 1.0.5 30 dnspython 2.1.0 31 docutils 0.16 32 falcon 2.0.0 33 flufl.bounce 3.0.1 34 flufl.i18n 2.0.2 35 flufl.lock 3.2 36 gunicorn 20.0.4 37 HyperKitty 1.3.3 38 idna 2.10 39 importlib-resources 5.1.0 40 lazr.config 2.2.3 41 lazr.delegates 2.0.4 42 mailman 3.3.2 43 mailman-hyperkitty 1.1.0 44 mailman-web 0.0.3 45 mailmanclient 3.3.2 46 Mako 1.1.4 47 MarkupSafe 1.1.1 48 networkx 2.5 49 nose 1.3.7 50 oauthlib 3.1.0 51 packaging 20.9 52 passlib 1.7.4 53 pip 21.0.1 54 postorius 1.3.3 55 psycopg2-binary 2.8.6 56 publicsuffix2 2.20191221 57 pycparser 2.20 58 Pygments 2.7.4 59 PyJWT 2.0.1 60 pyparsing 2.4.7 61 python-dateutil 2.8.1 62 python-editor 1.0.4 63 python3-openid 3.2.0 64 pytz 2021.1 65 rcssmin 1.0.6 66 readme-renderer 28.0 67 requests 2.25.1 68 requests-oauthlib 1.3.0 69 rjsmin 1.1.0 70 robot-detection 0.4 71 setuptools 39.2.0 72 six 1.15.0 73 SQLAlchemy 1.3.23 74 sqlparse 0.4.1 75 typing-extensions 3.7.4.3 76 urllib3 1.26.3 77 uWSGI 2.0.19.1 78 wcwidth 0.2.5 79 webencodings 0.5.1 80 wheel 0.36.2 81 Whoosh 2.7.4 82 zipp 3.4.0 83 zope.component 4.6.2 84 zope.configuration 4.4.0 85 zope.deferredimport 4.3.1 86 zope.deprecation 4.4.0 87 zope.event 4.5.0 88 zope.hookable 5.0.1 89 zope.i18nmessageid 5.0.1 90 zope.interface 5.2.0 91 zope.proxy 4.3.5 92 zope.schema 6.0.1 -- Carlos Souza

Issues with a DMARC record leading to message being shunted

Something with DMARC and tags. So I checked the DMARC record for the sending domain somenet.org. It is "v=DMARC1;p=none;pct=100;rua=mailto:postmaster@somenet.org;mailto:postmaster@somenet.org;ri=3600;fo=1;" which is syntactically incorrect. The extra ";mailto:postmaster@somenet.org" is wrong, I guess the tag "ruf=" is missing here! It should probably read "v=DMARC1;p=none;pct=100;rua=mailto:postmaster@somenet.org;ruf=mailto:postmaster@somenet.org;ri=3600;fo=1;" So, should mm3 somehow "catch" this error somehow? According to the DMARC specs, an syntactically incorrect DMARC record should be ignored / handled as if none were present. -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netz | Netzwerk-Administration Invalidenstraße 120/121 | D-10115 Berlin Tel. +49 30 450 570 155 ralf.hildebrandt(a)charite.de https://www.charite.de

Loops back to myself
by David Krantz 12 Jan '24

12 Jan '24

Hi, I have a problem with my Mailman 3-setup. The symptom is that postfix rejects non-existing addresses for my list domains with <adr(a)example.com>: mail for example.com loops back to myself What I guess happens happens is that postfix for some reason accepts the mail as it is for a relay domain and finds that it is not deliverable locally as the address does not exist locally and then tries to relay it on to the appropriate MX server, which is itself and then fails and generates a bounce message. This is a bit annoying as I have set up postfix to only accept valid addresses. I have set the transport_maps, local_recipient_maps and relay_domains to the files generated by MM3. I run an older version of MM3 (3.0) but prefer to fix this without upgrading as upgrading is a relatively big undertaking. This is mostly a backscatter problem for spam I guess. Any ideas of very simple and easy to forget things that I've probably missed? Cheers // David

Archive import fails: "IndexError: list index out of range"
by Johannes Rohr 06 Jan '24

I am now importing the archives of my old mailman2 installation. Unfortunately, with some of the larger and older lists, import fails halfway through, with an exception, the last message of which is IndexError: list index out of range Below is an example. This means that the last few years are missing from the archive in several lists. Are there any suggestions what I could do to still get them importet? Thanks!

Programmatically modify Thread-Topic *before* message is sent out the door?
by Thomas Ward 03 Jan '24

03 Jan '24

We use a custom plugin to do numeric thread stamping, which has been working well in the code system. However, it was discovered by Microsoft that Microsoft Outlook and OWA prioritize the Thread-Topic header over the Subject header, which results in the oddness we've experienced in MS365 clients in testing. During our tasks though a custom handler goes through during the pipeline and modifies the Subject field accordingly, adding a thread tag to it. While this is 'fragile' it does work; the only problem is that Thread-Topic doesn't get altered. Programmatically, how would we alter the Thread-Topic during the handler's processing to prepend the corresponding prefix/tag so that when the message actually goes out the door it is properly sending with the modified Thread-Topic?

Editing the "example.org" site
by Stephen J. Turnbull 03 Jan '24

03 Jan '24

Hi all, I don't know how many people will need this, but I just realized that you can edit Django's SITE 1 and (probably, 100% untested but I'm going on the clock so want to get this done quick :-) use that. When you add your first domain, there's a link in that page (not a button, a link!) to edit the domain list. Then you can click on the link to "example.org" in the list, and edit both display name (which I assumed) and the domain name. Maybe I'm just slow, but I've been adding SITE 2 = "Whatever site <whatever.tld>" the whole time. :-) But then you have to edit the SITE = 1 statement in settings.py (which I often forget and hilarity ensues). Of course adding a web site and editing settings.py (which you have to do anyway for other variables) works too, but this seems cleaner to me. Steve

Can't edit lists anymore: "Something went wrong HTTP Error 404"

When I try to edit any list at "postorius/lists/LISTNAME.SUBDOMAIN.DOMAIN.TLD/", I get this error. The lists are displayed correctly at "postorius/lists/". Selecting any of those lists leads to that error. First step of creating a new list is possible but I get the same error right after the creation of the new list.
