Mailing list welcome message won't update
by frances.du＠uq.edu.au Jan. 16, 2025

Jan. 16, 2025

Hi there, I have updated the welcome message for a mailing list by directly updating the file at: file:///var/lib/mailman3/templates/lists/[redacted].lists.[redacted].org.au/en/list:user:notice:welcome I then restarted theses services: mailman3, mailman3-web and nginx. But when I test subsribe to the mailing list, the welcome message does not update. GNU Mailman 3.1.1 (Between The Wheels) Postorius Version 1.1.2 Thank you for your help in advance. Frances

Postorius: Search field in lists overview
by Andreas Vetter Jan. 15, 2025

Jan. 15, 2025

Hi, is there a way to search lists in Postorius' Lists overview https://lists.example.com/mailman3/lists/?all-lists Well, one can change "results on page" to 200 and then use the search function of the browser, but that is some more clicks. -- Mit freundlichen Gruessen, Andreas Vetter

Find a smtp server to send out emails
by Leon Jan. 15, 2025

Jan. 15, 2025

Hi, This problem is not caused by mailman, but I still want to give it a shot here. I'm hosting a mailing list on top of mailman3. Emails are supposed to be sent out by AWS ses. However, ses requires that sender address must be verified, which leads to a problem that emails sent by subscribers to mailing list cannot be sent to other subcirbers, since their addresses are not verified. And it is impossible to verified every subscriber. Are there smtp service providers allowing unverified email address to send out emails, or do I have other solutions? Thanks. -- Best wishes, Leon

Random lmtp Timeout and Long Message Processing times
by Taber, Douglas R Jan. 9, 2025

Jan. 9, 2025

Hello- We’re seeing a seemingly random issue with message acceptance on our mailman instance where some messages sent from postfix to the lmtp listener timeout. It’s not consistent to any specific list or time of day, and messages are accepted on the next attempt by postfix to deliver the message to the lmtp. Additionally, there seems to be a similarly random delay in accepting and processing messages before they are sent to the list moderators or list members. The mailman smtp log snippet shows it stop receiving data prior to the DATA portion of the message after a 15min timeout: Jan 02 07:56:36 2025 (3601529) Available AUTH mechanisms: LOGIN(builtin) PLAIN(builtin) Jan 02 07:56:36 2025 (3601529) Peer: ('127.0.0.1', 45574) Jan 02 07:56:36 2025 (3601529) ('127.0.0.1', 45574) handling connection Jan 02 07:56:36 2025 (3601529) ('127.0.0.1', 45574) << b'220 lists.renci.org GNU Mailman LMTP runner 2.0' Jan 02 07:56:36 2025 (3601529) _handle_client readline: b'LHLO lists.renci.org\r\n' Jan 02 07:56:36 2025 (3601529) ('127.0.0.1', 45574) >> b'LHLO lists.renci.org' Jan 02 07:56:36 2025 (3601529) ('127.0.0.1', 45574) << b'250-lists.renci.org' Jan 02 07:56:36 2025 (3601529) ('127.0.0.1', 45574) << b'250-SIZE 33554432' Jan 02 07:56:36 2025 (3601529) ('127.0.0.1', 45574) << b'250-8BITMIME' Jan 02 07:56:36 2025 (3601529) ('127.0.0.1', 45574) << b'250 HELP' Jan 02 07:56:36 2025 (3601529) _handle_client readline: b'MAIL FROM:010001942716aa05-637d21f8-9794-473f-9e8b-06ca08025ef1-000000@mail.verify.signin.aws<mailto:010001942716aa05-637d21f8-9794-473f-9e8b-06ca08025ef1-000000@mail.verify.signin.aws> SIZE=20254\r\n' Jan 02 07:56:36 2025 (3601529) ('127.0.0.1', 45574) >> b'MAIL FROM:010001942716aa05-637d21f8-9794-473f-9e8b-06ca08025ef1-000000@mail.verify.signin.aws<mailto:010001942716aa05-637d21f8-9794-473f-9e8b-06ca08025ef1-000000@mail.verify.signin.aws> SIZE=20254' Jan 02 07:56:36 2025 (3601529) ('127.0.0.1', 45574) sender: 010001942716aa05-637d21f8-9794-473f-9e8b-06ca08025ef1-000000(a)mail.verify.signin.aws<mailto:010001942716aa05-637d21f8-9794-473f-9e8b-06ca08025ef1-000000@mail.verify.signin.aws> Jan 02 07:56:36 2025 (3601529) ('127.0.0.1', 45574) << b'250 OK' Jan 02 07:56:36 2025 (3601529) _handle_client readline: b'RCPT TO:adcircaws@lists.RENCI.org<mailto:adcircaws@lists.RENCI.org>\r\n' Jan 02 07:56:36 2025 (3601529) ('127.0.0.1', 45574) >> b'RCPT TO:adcircaws@lists.RENCI.org<mailto:adcircaws@lists.RENCI.org>' Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 45574) recip: adcircaws(a)lists.RENCI.org<mailto:adcircaws@lists.RENCI.org> Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 45574) << b'250 Ok' Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 45574) EOF received Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 45574) connection timeout Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 45574) Connection lost during _handle_client() Jan 02 08:12:26 2025 (3601529) Available AUTH mechanisms: LOGIN(builtin) PLAIN(builtin) Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 45574) connection lost Jan 02 08:12:26 2025 (3601529) Peer: ('127.0.0.1', 33138) Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) handling connection Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) << b'220 lists.renci.org GNU Mailman LMTP runner 2.0' Jan 02 08:12:26 2025 (3601529) _handle_client readline: b'LHLO lists.renci.org\r\n' Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) >> b'LHLO lists.renci.org' Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) << b'250-lists.renci.org' Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) << b'250-SIZE 33554432' Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) << b'250-8BITMIME' Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) << b'250 HELP' Jan 02 08:12:26 2025 (3601529) _handle_client readline: b'MAIL FROM:010001942716aa05-637d21f8-9794-473f-9e8b-06ca08025ef1-000000@mail.verify.signin.aws<mailto:010001942716aa05-637d21f8-9794-473f-9e8b-06ca08025ef1-000000@mail.verify.signin.aws> SIZE=20254\r\n' Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) >> b'MAIL FROM:010001942716aa05-637d21f8-9794-473f-9e8b-06ca08025ef1-000000@mail.verify.signin.aws<mailto:010001942716aa05-637d21f8-9794-473f-9e8b-06ca08025ef1-000000@mail.verify.signin.aws> SIZE=20254' Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) sender: 010001942716aa05-637d21f8-9794-473f-9e8b-06ca08025ef1-000000(a)mail.verify.signin.aws<mailto:010001942716aa05-637d21f8-9794-473f-9e8b-06ca08025ef1-000000@mail.verify.signin.aws> Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) << b'250 OK' Jan 02 08:12:26 2025 (3601529) _handle_client readline: b'RCPT TO:adcircaws@lists.RENCI.org<mailto:adcircaws@lists.RENCI.org>\r\n' Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) >> b'RCPT TO:adcircaws@lists.RENCI.org<mailto:adcircaws@lists.RENCI.org>' Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) recip: adcircaws(a)lists.RENCI.org<mailto:adcircaws@lists.RENCI.org> Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) << b'250 Ok' Jan 02 08:12:26 2025 (3601529) _handle_client readline: b'DATA\r\n' Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) >> b'DATA' Jan 02 08:12:26 2025 (3601529) ('127.0.0.1', 33138) << b'354 End data with <CR><LF>.<CR><LF>' Anyone have any thoughts on next troubleshooting steps on this one?

Feature request, hyperkitty, low volume lists
by Alain D D Williams Jan. 9, 2025

Jan. 9, 2025

I host several low volume mail lists. Typically these are announcement lists where low volume is deliberate -- too many emails and people might unsubscribe. These lists are archived but most months there are not any postings. Browsing the archives can mean much clicking to find content, this is done better with mailman2. My request is to make finding content easier. Possibilities: • On the summary (left hand side) put the number of posts after the month name • Only show months (left hand side) where there are any posts For an example see: https://fridayfolk.phcomp.co.uk/mailman3/hyperkitty/list/announce@fridayfol… (There is one post in November) Regards -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers.

possible backscatter attack using Mailman3 servers
by David Newman Jan. 5, 2025

Jan. 5, 2025

Greetings. On a system running Mailman 3.3.9 and Postfix, I'm seeing about 20-30 entries per day in the Postfix queue where it appears a Gmail user signs up for a mailing list that requires confirmation, and Gmail responds that the user is too busy to handle requests. There are no publicly advertised email lists on this server, and I don't ever see anything in the Mailman logs indicating the user ever tried signing up. I've pasted the mail.log transaction below, with only slight obfuscation: - "mail10.example1.com" is this server's canonical hostname - lists are hosted on "lists.example2.com" and "mail.example3.com" - "someuser9413(a)gmail.com" is the user supposedly signing up Thanks in advance for clues on determining where these requests are coming from, and how I might block them. I have a strong interest in having my server not amplifying backscatter traffic like this. Alternatively, if this is a Postfix problem, please let me know that too. dn Jan 3 10:29:22 mail10 postfix/postscreen[4052406]: CONNECT from [::1]:55274 to [::1]:25 Jan 3 10:29:22 mail10 postfix/postscreen[4052406]: WHITELISTED [::1]:55274 Jan 3 10:29:22 mail10 postfix/postscreen[4052406]: using backwards-compatible default setting respectful_logging=no for client [::1]:55274 Jan 3 10:29:22 mail10 postfix/smtpd[4052407]: connect from localhost[::1] Jan 3 10:29:22 mail10 postfix/smtpd[4052407]: discarding EHLO keywords: CHUNKING Jan 3 10:29:22 mail10 postfix/smtpd[4052407]: 4YPsYG1X2xzHQfw: client=localhost[::1] Jan 3 10:29:22 mail10 postfix/cleanup[4052628]: 4YPsYG1X2xzHQfw: message-id=<173592896219.2314.15515568084960961396(a)mail10.example1.com> Jan 3 10:29:22 mail10 postfix/smtpd[4052407]: disconnect from localhost[::1] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 Jan 3 10:29:22 mail10 postfix/qmgr[3635053]: 4YPsYG1X2xzHQfw: from=<postmaster(a)example2.com>, size=901, nrcpt=1 (queue active) Jan 3 10:29:22 mail10 postfix/10025/smtpd[4052639]: connect from localhost[127.0.0.1] Jan 3 10:29:22 mail10 postfix/10025/smtpd[4052639]: discarding EHLO keywords: CHUNKING Jan 3 10:29:22 mail10 postfix/10025/smtpd[4052639]: 4YPsYG33SkzHSdN: client=localhost[127.0.0.1] Jan 3 10:29:22 mail10 postfix/cleanup[4052628]: 4YPsYG33SkzHSdN: message-id=<173592896219.2314.15515568084960961396(a)mail10.example1.com> Jan 3 10:29:22 mail10 postfix/10025/smtpd[4052639]: disconnect from localhost[127.0.0.1] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 Jan 3 10:29:22 mail10 postfix/qmgr[3635053]: 4YPsYG33SkzHSdN: from=<postmaster(a)example2.com>, size=1939, nrcpt=1 (queue active) Jan 3 10:29:22 mail10 amavis[4017234]: (4017234-09) Passed CLEAN {RelayedInternal}, MYNETS/MYUSERS LOCAL [::1]:55274 ESMTP/ESMTP <postmaster(a)example2.com> -> <someuser9413(a)gmail.com>, (), Queue-ID: 4YPsYG1X2xzHQfw, Message-ID: <173592896219.2314.15515568084960961396(a)mail10.example1.com>, mail_id: P9P7GnranpAW, b: Zp0DirpBL, Hits: -, size: 900, queued_as: 4YPsYG33SkzHSdN, Subject: "[mail.example3.com] Please Confirm Your Email Address", From: <postmaster(a)example2.com>, helo=mail10.example1.com, dkim_new=dkim:example1.com, 217 ms Jan 3 10:29:22 mail10 postfix/amavis/smtp[4052633]: 4YPsYG1X2xzHQfw: to=<someuser9413(a)gmail.com>, relay=127.0.0.1[127.0.0.1]:10024, delay=0.24, delays=0.02/0/0.01/0.21, dsn=2.0.0, status=sent (250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 4YPsYG33SkzHSdN) Jan 3 10:29:22 mail10 postfix/qmgr[3635053]: 4YPsYG1X2xzHQfw: removed Jan 3 10:29:22 mail10 postfix/smtp[4052642]: Trusted TLS connection established to gmail-smtp-in.l.google.com[2607:f8b0:4023:c0d::1b]:25: TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature ECDSA (prime256v1) server-digest SHA256 Jan 3 10:29:22 mail10 postfix/smtp[4052642]: 4YPsYG33SkzHSdN: host gmail-smtp-in.l.google.com[2607:f8b0:4023:c0d::1b] said: 450-4.2.1 The user you are trying to contact is receiving mail at a rate that 450-4.2.1 prevents additional messages from being delivered.

Hyperkitty performance problem
by Tobias Diekershoff Jan. 1, 2025

Jan. 1, 2025

Hey all, last week we caught some AI bots causing high LOAD on our mailman3 servers archive, that we blocked with nginx rules. I'm not sure if it is related to this incident, but we noticed this when analyzing the log files at the time. In the mailman.log hyperkitty is listed 10k times and more to archive a single mail over the time of 2h, seemingly all with the same process ID > (1186) HyperKitty archived message [...] The mailman3-web.log has matching log entries that the mail was archived > hyperkitty.views.mailman Archived message every 0.5 seconds. In the web interface to the archive, the mail is only listed once though. My suspicion is, that these archiving processes are now overloading the system, preventing a timely catching up work of the queued messages. I could not find anything in the Mailman3 nor Hyperkitty documentation to better distribute the system resources to the Mailman runner or prevent Hyperkitty to restart archiving a mail over and over again. Any hint about where to look for the reason of this is highly appreciated.
