Issues with a DMARC record leading to message being shunted

Hi! Recently a mail was not being distributed via our MM3 instance; I searched the logs and found: Dec 22 04:54:27 2023 (24) ACCEPT: <1d431542-b386-467b-8bf2-305f19ee7eb4(a)somenet.org> Dec 22 04:54:28 2023 (28) Uncaught runner exception: list index out of range Dec 22 04:54:28 2023 (28) Traceback (most recent call last): File "/usr/lib/python3.10/site-packages/mailman/core/runner.py", line 179, in _one_iteration self._process_one_file(msg, msgdata) File "/usr/lib/python3.10/site-packages/mailman/core/runner.py", line 272, in _process_one_file keepqueued = self._dispose(mlist, msg, msgdata) File "/usr/lib/python3.10/site-packages/mailman/runners/pipeline.py", line 37, in _dispose process(mlist, msg, msgdata, pipeline) File "/usr/lib/python3.10/site-packages/mailman/core/pipelines.py", line 53, in process handler.process(mlist, msg, msgdata) File "/usr/lib/python3.10/site-packages/mailman/handlers/validate_authenticity.py", line 125, in process authenticate(msg, msgdata) File "/usr/lib/python3.10/site-packages/mailman/utilities/retry.py", line 44, in f_retry return f(*args, **kwargs) File "/usr/lib/python3.10/site-packages/mailman/handlers/validate_authenticity.py", line 93, in authenticate auth_result = authenticate_message( File "/usr/lib/python3.10/site-packages/authheaders/__init__.py", line 395, in authenticate_message dmarc_result = check_dmarc(msg, spf_result, dkim_result, dnsfunc=dnsfunc, psddmarc=psddmarc) File "/usr/lib/python3.10/site-packages/authheaders/__init__.py", line 343, in check_dmarc result, result_comment, from_domain, policy = dmarc_per_from(from_domain, spf_result, dkim_result, dnsfunc, psddmarc) File "/usr/lib/python3.10/site-packages/authheaders/__init__.py", line 90, in dmarc_per_from record, orgdomain = receiver_record(from_domain) File "/usr/lib/python3.10/site-packages/authheaders/dmarc_lookup.py", line 117, in receiver_record retval = lookup_receiver_record(hostSansDmarc, dnsfunc) File "/usr/lib/python3.10/site-packages/authheaders/dmarc_lookup.py", line 92, in lookup_receiver_record tags = answer_to_dict(str(result)) File "/usr/lib/python3.10/site-packages/authheaders/dmarc_lookup.py", line 42, in answer_to_dict retval = {t[0].strip().lower(): t[1].strip().lower() for t in rawTags} File "/usr/lib/python3.10/site-packages/authheaders/dmarc_lookup.py", line 42, in <dictcomp> retval = {t[0].strip().lower(): t[1].strip().lower() for t in rawTags} IndexError: list index out of range Dec 22 04:54:28 2023 (28) SHUNTING: 1703220868.1418982+b27f5db154375fcd2c418d467172e4aad0d3d57a So the message has been shunted, due to this error. 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

Digests not working correctly
by Joel Lord 08 Jun '24

08 Jun '24

So I seem to have problems with both periodic AND size-triggered digests. Size first, this is simpler. Just got one sent out, clearly triggered by a new email getting added to the queued up messages, but the setting for the list is the default 30KB and the digest came out at 23.2 KB. Is it measuring the accumulated queue as size on disk including metadata and filesystem block sizes or something, rather than the size of what the emailed digest will be? Periodic is much more complicated, even to explain. I have the cron job running nightly at 11:00 PM and it certainly seems to be working, except for one really odd thing. The list also definitely has periodic digests enabled in the web UI. This is a very bursty list, so it will go mad with traffic for a few weeks and then will go mostly idle for a month or so. The first digest of a burst is definitely size-triggered, but pretty reliably it has the last few messages from the previous burst in there. So the one I got today had three messages from today and one message from May 4th. But that May 4th message should have gone out at 11:00 PM on May 4th with the daily digest and then gotten flushed from the pending digest queue, right? -- Joel Lord

Change config to create a new list with all archives off
by Tibor Molnar 21 Apr '24

Can archiving be changed anywhere in mailman3 configs, so then all new lists created do not archive by default?

Mailman 3 hosting query
by Bill Robertson 18 Apr '24

18 Apr '24

Hi I'm investigating the possibility of transferring a fairly small mailing list I own from Google Groups to MM3 via a hosting service. I'd appreciate any pointers regarding what I should be looking out for with companies that offer this service It also seems very hard to find out which hosting companies are worth considering (In particular, reliability and support are important) Any help much is much appreciated Thanks

mailman3 digest sending questions and also adding docker to the mix
by bob B 17 Apr '24

17 Apr '24

So I have been down the digest rabbit hole. So to confirm my assumptions/findings: Digest size threshold---- means when the total size of held messages hits this setting, a digest is sent Digest Volume Frequency. ---- specifies when the digest volume number gets incremented for digest messages, IT DOES NOT send out digests based on the setting, daily, weekly ... So what does the GUI setting "Send Digest Periodically yes no" do? how periodically does it send digests, if this is set to yes? If I want to send a digest out for a list every day, or every week, how do I set that, especially in the docker environment? Is this something that can be configured in the GUI and configured by each of my list admins? I found that ”'mailman digests --periodic' via cron” should be set in googling, but does that mean I have to do a cron job for any list that wants a scheduled digest sent? My use case is, that I have a list admin who set a size threshold, but regardless of that, they also want their list digest sent out daily, they thought it was the "Digest Volume Frequency" setting but that is not correct. However in their testing they are not getting daily digest, they are getting digests only when the threshold is reached, BUT they have "Send Digest Periodically" set to "yes" and "Enable Digests" is set to "yes"

Hi All, I've just installed MM3 on a fresh Debian 12 using the Virtualenv method.

Sibling lists in Mailman3
by Markus Grandpre 10 Apr '24

10 Apr '24

Dear list, after I migrated a list from Mailman21 to Mailman3 I missed the Mailman21 setting "regular_include_lists" (or something similar) in Mailman3. How are sibling lists treated in Mailman3? Thank you in advance for your answers.

Mailman stops processing....... where to start looking for root cause?
by bob B 02 Apr '24

02 Apr '24

Today was the 2nd time mailman stopped sending out mail, it receives mail but sends nothing out. To resolve the issue I restarted the mailman services and then all the incoming/queued mail was sent out... last time this happened was 21 days ago.... Before that, it has been rock solid for years. We are running in a docker environment with no recent changes. On the host in /var/log/maillog, I see the mail coming in and going to mailman in docker. for docker, the mailman logs are in /opt/mailman/core/var/logs in /opt/mailman/core/var/logs/smtp.log ---------- I see the messages coming in /opt/mailman/core/var/logs/debug.log ------------ is empty /opt/mailman/core/var/logs/mailman.log -------------- I do not see anything that looks like it had an issue So where can I look to try to determine a cause? If it happens again, what and where can I cook to troubleshoot before restarting the service? Thanks

Seeking help completing a useful installation
by Hugh Esco 30 Mar '24

30 Mar '24

I have more fully documented where I am at with this attempt to build a working installation of mm3 at this link: https://gitlab.com/mailman/django-mailman3/-/issues/73 My questions include: - the template for /etc/mailman3/mailman.cfg, defines vardir, but no DATA_DIR. See test failure #1 (closed) <http:///mailman/django-mailman3/-/issues/1>, above. Where does that want to be? Any issue with putting the mm3.db next to the mm3_web.db at /opt/mailman/mm/var/data? - there are two possible virtualenv's in my build: (a) /opt/mailman/venv/ and (b) /opt/mailman/.pyenv/. I say more about these below. Which do I want to use in this instance? I'm guessing the latter where the mailman3 libraries are published, but have doubts. The link above urges a dependency on python ^3.11, but bookworm provides only python 3.8, so I used pyenv to satisfy the requirement. It wanted to deploy to its own path, though perhaps there is some switch which would consolidate everything under /opt/mailman/venv/. I do not work with python enough to know. - attempts to run bin/mailman-web startapp mm3web fail to add any new processes to the process list. bin/mailman-web start fails with errors. What change of state to the server should I expect from running this command? How do I test for success? If startapp is the correct invocation, what argument does it want on a working installation? - having run the command in the previous point, I see nothing in the browser except for the apache starter page at the root path '/'. None of the paths defined in the apache2 configuration seem to offer any joy. I assume that uwsgi wants to proxy the requests to a running mailman-web service somehow, but that no such service is found. I see one hopeful line in the log at: /opt/mailman/mm/var/logs/mailman.log "GET /3.1/lists?count=10&page=1 HTTP/1.1" 200 90 "-" "GNU Mailman REST client v3.3.5" - I assume that once I get apache2 wired to a running application through the uwsgi proxy, that I can proceed to create an admin user, use it to explore the web gui, and begin to consider how to migrate my legacy mm2.1 lists into the new installation. Any further help crossing the finish line would be appreciated. Thanks, -- Hugh
