Does Mailman 3 log subscribes and unsubscribes for each list the way Mailman 2 did? Brian

Questions regarding message acceptance
by Pawel Grzywaczewski 19 Sep '24

19 Sep '24

Hello, I have few questions regarding usage of Mailman3: 1) We have list1 and list2 with members. Can we specify that all members of list1 can post messages to list2? We could potentially write a script that would synchronize members of another list to “Accept these non-members” of another list, but with thousands of lists it will be difficult to maintain lists in synchro. So perhaps there is a concept of adding another list to “Accept these non-members” and mailman real-time evaluate membership of another list upon message arrival? 2) In explanation of “Accept these non-members” it’s written: “While non-regexp addresses can be entered here, it is preferred to add the address as a nonmember and set the nonmember's Moderation to Default Processing”. I noticed that if someone posts to a list then he is added automatically to non-members. Which means that next time he will be able to post. My understanding is that it’s better to use the feature “Accept these non-members”. Am I correct? Thank you, Paweł

Disabled by bounce
by Allan Hansen 11 Sep '24

Hi all, Apparently Google just started to get very aggressive about DKIM settings. Some hundreds of my subscribers have had their subscriptions disabled because of Google's bounces. I tried to 'Enable' some of them, expecting that their bounce scores would be reset, but when I list the users, the bounce scores are still 5. Please advise. Will enabling them without the bounce score being reset just cause the server to disable them again. Yours, Allan

Does Mailman 3 have something similar to https://www.msapiro.net/scripts/last_post.py displaying the last post time for a list or all lists?

MM3 generates long lines?
by peter＠chubb.wattle.id.au 28 Jul '24

I'm seeing emails being dropped when mm3 talks to the local smtp server, with log errors like: 2021-06-23 15:42:24 1lvvea-007r8u-VN H=localhost (<FQDN>) [::1] F=<announce-bounces@<FQDN>> rejected after DATA: maximum allowed line length is 998 octets, got 1036 The email itself did not have such long lines AFAICT. I can disable line length checking on the mailserver, but that sounds like a recipe for the next one along to drop the email. Peter C

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"
