Internal Server Error: /mailman3/postorius/lists/.../held_messages - humanize: where to put?
by Flo Feb. 16, 2026

Feb. 16, 2026

Hi, I have setup in Debian Trixie mailman3-full and came that far, that I have created a mailing list. I can sent emails to the members. However when I send from an email which is non-member the message is held. If I want to accept this message as list admin, I get: `An error occurred while processing your request.` And I get an email: `Internal Server Error: /mailman3/postorius/.../held_messages TemplateSyntaxError at /postorius/lists/.../held_messages 'humanize' is not a registered tag library.

In this file I I configured Django. However it's not in the Python path as written in the error email above. So maybe I have to find a different settings file. Can anyone advise me where I can find the error I have in my configuration? Thanks in advance. Flo

Issues with Mail delivery after Mailman 3 installation

Feb. 12, 2026

I finished installing mailman3, setup lmtp and smtp for mail delivery and I followed the instructions on the mailman 3 installation page. Mail delivery doesn't work and the logs show this; Jan 31 12:53:53 lists postfix/lmtp[4131588]: 3B8121A89BD: to=<systems(a)lists.sugarlabs.org>, relay=127.0.0.1[127.0.0.1]:24, delay=11119, delays=11072/0.01/0.01/47, dsn=4.3.0, status=deferred (host 127.0.0.1[127.0.0.1] said: 451 4.3.0 <systems(a)lists.sugarlabs.org> Temporary internal error (in reply to RCPT TO command)) 106029 Jan 31 12:53:53 lists postfix/lmtp[4131587]: 052BB1A8975: to=<mailman(a)lists.sugarlabs.org>, orig_to=<mailman>, relay=localhost[127.0.0.1]:24, delay=1432, delays=1385/0.02/0.01/47, dsn=4.3.0, status=deferred (host localhost[127.0.0.1] said: 451 4.3.0 <mailman(a)lists.sugarlabs.org> Temporary internal error (in reply to RCPT TO command)) Jan 31 12:53:53 lists dovecot: lmtp(4131586): Disconnect from 127.0.0.1: Logged out (state=READY) Jan 31 12:53:53 lists postfix/local[4131582]: F2DB61A8952: passing <mailman(a)lists.sugarlabs.org> to transport=lmtp Jan 31 12:53:53 lists dovecot: lmtp(4131590): Disconnect from 127.0.0.1: Logged out (state=READY) Jan 31 12:53:53 lists dovecot: lmtp(4131589): Disconnect from 127.0.0.1: Logged out (state=READY) Jan 31 12:53:53 lists postfix/local[4131584]: D172A1A8A0E: passing <mailman(a)lists.sugarlabs.org> to transport=lmtp Jan 31 12:53:53 lists dovecot: lmtp(4131586): Connect from 127.0.0.1 Jan 31 12:53:53 lists dovecot: lmtp(4131589): Connect from 127.0.0.1 Jan 31 12:53:54 lists postfix/lmtp[4128841]: connect to localhost[::1]:24: Connection refused Jan 31 12:53:54 lists postfix/lmtp[4128840]: connect to localhost[::1]:24: Connection refused Jan 31 12:53:54 lists postfix/lmtp[4128841]: 348981A8A2A: to=<mailman(a)lists.sugarlabs.org>, orig_to=<mailman>, relay=none, delay=113, delays=0.04/52/61/0, dsn=4.4.1, status=deferred (connect to localhost[::1]:24: Connection refused) Jan 31 12:53:54 lists postfix/lmtp[4128840]: 5382D1A8A27: to=<mailman(a)lists.sugarlabs.org>, orig_to=<mailman>, relay=none, delay=173, delays=0.02/111/61/0, dsn=4.4.1, status=deferred (connect to localhost[::1]:24: Connection refused) Jan 31 12:53:56 lists dovecot: lmtp(4128842): Disconnect from 127.0.0.1: Connection closed (state=READY) Jan 31 12:53:56 lists dovecot: lmtp(4127392): Disconnect from 127.0.0.1: Connection closed (state=READY) Jan 31 12:54:02 lists postfix/pickup[4131579]: 1D3E71A8A1C: uid=1005 from=<mailman> Jan 31 12:54:02 lists postfix/cleanup[4131852]: 1D3E71A8A1C: message-id=<20260131205402.1D3E71A8A1C(a)lists.sugarlabs.org> Jan 31 12:54:02 lists postfix/qmgr[4131580]: 1D3E71A8A1C: from=<mailman(a)lists.sugarlabs.org>, size=919, nrcpt=1 (queue active) Jan 31 12:54:53 lists dovecot: auth: Fatal: passdb passwd-file: Missing args Jan 31 12:54:53 lists dovecot: master: Error: service(auth): command startup failed, throttling for 60.000 secs Jan 31 12:54:53 lists dovecot: lmtp(mailman(a)lists.sugarlabs.org)<4131586><qMl1NuFrfmkCCz8AOj1W/w>: Error: auth-master: userdb lookup(mailman(a)lists.sugarlabs.org): Disconnected unexpectedly Jan 31 12:54:53 lists dovecot: lmtp(4131586): Error: lmtp-server: conn 127.0.0.1:56008 [2]: rcpt mailman(a)lists.sugarlabs.org: Failed to lookup user mailman(a)lists.sugarlabs.org: Internal error occurred.

Phantom Email Address in Nonmember List
by Steve Brown Jan. 31, 2026

Jan. 31, 2026

Have an issue that is more of a puzzle than a problem. No real harm done. So don't spend much time on it if you don't recognize the issue. I am administrator for a small list, radg(a)lists.radg.us, hosted by Mailmanlists.net. They are trying hard to figure it out but so far unsuccessful. Looking at the headers of emails sent from steve(a)stevebrown.us to the list and boomeranged back to me, I see a line “X-MailFrom: bounce+66273f.99dcd9c-radg=lists.radg.us(a)stevebrown.xn--us-02t. I gather that it is designating the return path where a message would be sent if there was a delivery problem. From its position in the header, I suspect it is added as they pass through Mailgun, maybe related to DKIM. I am hoping you might know why that bounce address is recognized by Mailman 3 as a real address for my emails, but not for others, even from my wife’s computer traversing the same path from our home to the Mailman 3 server. The Mailman installation does get and process the post, but also puts the “bounce+,,,” address in its list of nonmembers. Mailmanlists.net hasn’t figured out the behavior. I can provide full header information if that would help. My understanding of how headers work is very limited. Steve Brown

Domain defaults for new lists
by Peter Chubb Jan. 30, 2026

Jan. 30, 2026

Hi Folks, Is there a simple way to set up the defaults for any newly created lists? We've had a few cases recently where in the time between creating a mass-populated list and making it private it's been inundated with spam. I'd like to change the defaults so newly-created lists are private and have private archives, new members are moderated, etc., to give time for the list to be set up completely before announcing it to the world.

Disabling Mass operations
by iMark Jan. 24, 2026

Jan. 24, 2026

Hi All, Can anyone give me a pointer on disabling "Mass operations" (subscribe/removal) in Postorius. Just removing the menu link from the list-owners administration pages would be a good start. On "list-by-list" would be brilliant, but even server-wide would do the job. Cheers, Mark

Change Member's Address
by dap1＠bellsouth.net Jan. 15, 2026

How do I manually change a member's address? I can't find any way to do that from the mailman-web pages. Do I need to do it within MySQL somewhere? TIA.

Any known cases of "non-members" who aren't explicitly allowed to send to the list with a default rule of "discard" on a list getting through?
by Thomas Ward Jan. 10, 2026

Jan. 10, 2026

We just noticed an oddness in a client's system. Someone sent to a members-only list and it 'got past' moderation controls. The list is set to not allow non-members to send to the list, but somehow it got through the default rule of "discard (no notification)" for a non-member and got to the list. The only oddness I can tell is that there was an emoji (unicode) in the subject line but as I understand how Mailman works, this should NOT have impacted anything, as the sender filter bits happen earlier in message processing. Has *anyone* seen any cases like this before? If this is repeatable or a known issue, it deserves a CVE security bug because this is a **severe** problem.
