Cannot connect to SMTP server
by mkummini＠cmi.ac.in Aug. 14, 2022

Aug. 14, 2022

Hello. I am setting up a new mailman3 server (debian 11). `mailman3-full` is installed on the same server as postfix (our MTA). There is just one test mailing list now. When I send a message to it (I am a subscriber), mailman3 accepts the message through LMTP. Both the postfix log and mailman.log confirm this. Postfix log: Aug 14 03:21:25 mail postfix/lmtp[4097036]: 44E49272437D: to=<testlist(a)cmi.ac.in>, relay=127.0.0.1[127.0.0.1]:8024, delay=0.15, delays=0.02/0.03/0.01/0.09, dsn=2.0.0, status=sent (250 Ok) mailman.log: Aug 14 03:21:26 2022 (4096856) ACCEPT: <Yvgc3WsoFlpZbypw(a)cmi.ac.in> (The digest.mmdf file shows the test message I sent. Hence mailman3 has received the message from postfix.) However, after this, the postfix log does not show any attempt by mailman3 to send the message to the list members. The following runners have started (after the most recent mailman3 restart) Aug 14 03:19:53 2022 (4096853) archive runner started. Aug 14 03:19:53 2022 (4096863) retry runner started.

However, I get the following line each time I do a restart Aug 14 03:19:57 2022 (4096859) Cannot connect to SMTP server localhost on port 587 I tried to specify the name of the postfix server, though it runs on the same machine as mailman3, and the different ports : 25, 465 and 587; they all raise the same error. Following <https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/runners/do…>, I tried to create an outgoing test runner, but that resulted in the following errors. >>> from mailman.runners.outgoing import OutgoingRunner >>> from mailman.testing.helpers import make_testable_runner >>> outgoing = make_testable_runner(OutgoingRunner, 'out') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3/dist-packages/mailman/testing/helpers.py", line 92, in make_testable_runner return EmptyingRunner(name) File "/usr/lib/python3/dist-packages/mailman/testing/helpers.py", line 79, in __init__ super().__init__(*args, **kws) File "/usr/lib/python3/dist-packages/mailman/runners/outgoing.py", line 53, in __init__ super().__init__(slice, numslices) File "/usr/lib/python3/dist-packages/mailman/core/runner.py", line 63, in __init__ section = getattr(config, 'runner.' + name) File "/usr/lib/python3/dist-packages/mailman/config/config.py", line 123, in __getattr__ return getattr(self._config, name) AttributeError: 'NoneType' object has no attribute 'runner.out' Here are the lines in mailman.cfg referring to smtp smtp_secure_mode : starttls smtp_host: localhost smtp_port: 587 If you could suggest how I could fix this issue, it would be great.

RE in Ban List
by Peter Chubb Aug. 12, 2022

Aug. 12, 2022

Hi I tried to add the regular expression sales@.* to the ban list for one of my lists and got: An error occurred: Invalid Parameter "email": Expected a valid email address or regular expression, got sales@.*. Now, 'sales@.*' _is_ a valid regular expression --- so why did it fail? (I wanted to ban that set of addresses, because we get an awful lot of chinese spam from sales@some-company-name where the company name is variable) Peter C

MM3 not processing some mails from specific user
by Stefan Bauer Aug. 12, 2022

Aug. 12, 2022

Hi, we are running MM3¹ and from time to time, a mail to a mailing list is not processed by MM. MM sees the mail but still does nothing with it. If another user is sending _same_ mail, it is processed. Any idea what that could be? Here are some logs: Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) handling connection Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'LHLO mal01.mydomain.tld' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'MAIL FROM:<john.doe(a)mydomain.tld>' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) sender: john.doe(a)mydomain.tld Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'RCPT TO:<ssa(a)mydomain.tld>' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) recip: ssa(a)mydomain.tld Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'DATA' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'QUIT' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) connection lost Here is a snipped from same user, but different mail that is also not processed by MM: Subject: =?iso-8859-1?Q?Kleine_=C4nderung?= From: john.doe(a)mydomain.tld To: =?us-ascii?Q?ssa=40mydomain=2Etld?= <ssa(a)mydomain.tld> Date: Wed, 10 Aug 2022 12:33:36 +0000 Mime-Version: 1.0 Content-Type: multipart/alternative; boundary="=_m+9Z-w1zPVUy50id4xiOsxEs50Bl3xTDSq7AWqqonRf21H5c" Thread-Index: AdistWce8WLKbSqIReeBnR+y5yR5Mw== Message-Id: <kcEE.3C4Toxi/SomLpNH7qUNdhg.gBB2y7Ws2AE(a)mx1.mydomain.tld> This is a multi-part message in MIME format.

Mailman recovery test did not go as planned
by bob B Aug. 9, 2022

Aug. 9, 2022

I have a test Mailman 3 environment. We are using docker, and we are running the database outside of docker in mysql. I need to perform a DR recovery test. I shut down Mailman in docker (mailman-core & mailman-web, the only docker images I have running for Mailman). While Mailman was stopped, I had our database team take a backup dump of the database. I then restarted Mailman in docker. I threw some more messages at a test list. I validated that the new messages were delivered, and showed up in the archive. I shut down Mailman again. I had the database team restore the Mailman database from the backup. I started Mailman I logged into Mailman I was expecting to see the messages in the archive prior to the backup and all the messages after the backup would be gone. When went into the list archive, I get a spinning icon and no messages showed up. I quit, restarted my browser, and logged in again, and the same thing. I then sent a test message to the list and the message was delivered to the list. Then when I went to check the archive, the spinning icon was gone and that test message was there along with all the messages before the backup was taken. Is this normal? After a restore did the new message cause a refresh of archived messages etc? Is there a way to do this without sending a message to a list after a restoration of the database? Are there better steps I should take when restoring the database? Thanks

Detectors and Bounces
by summersan＠nclack.k12.or.us Aug. 5, 2022

Aug. 5, 2022

Hello All, I've recently upgraded a Mailman 3 server from Debian 10.12 to Debian 11.4 [1]. In that process, I've also upgraded Mailman 3 from version 3.3.4 to version 3.3.5. I think the following guide was originally used when setting up Mailman 3 on the present server: https://wiki.list.org/DOC/Howto_Install_Mailman3_On_Debian10 . After that upgrade process, I've noticed that at least one `mailman` process and one `postgres` process were at something like 40 %CPU or higher for extended periods of time (seen using `top` command). Upon further inspection, and through some research online, it seemed like the issue might have to do with bounces (maybe not processing or something) [2][3][4][5][6][7][8]. In my logcheck logs, I was seeing this message multiple times a second: `Running detector: <class 'flufl.bounce._detectors.dsn.DSN'>` I ended up trying to clear out the `/opt/mailman/mm/var/queue/bounces` and `/opt/mailman/mm/var/locks` directories to see if that would help. There seemed to be some sort of positive change, because the log message "spamming" seemed to decrease. The high %CPU for the `mailman` and `postgres` processes in question also seemed to go down over time. But the related `mailman` process would still run at a high %CPU from time to time. I tried checking the `mailman` process using `strace` at some point, but I didn't see an easily evident cause for what was going on—from what I remember, there was something about a "POLLIN" or something that kept looping. When I go to check the same `mailman` process with `strace` today, I just see occasional messages like this: `select(0, NULL, NULL, NULL, {tv_sec=45, tv_usec=43171}) = 0 (Timeout)` My Questions: Is it normal to see large amounts of `Running detector: <class 'flufl.bounce._detectors.dsn.DSN'>` lines in logs? Should there normally be other detectors listed in the logs beyond the `DSN` one? If so, is there a setting I can change somewhere to make this happen? For reference, I can only find one other logcheck log that shows a `Running detector: <class 'flufl.bounce._detectors.dsn.DSN'>` line from before the recent Mailman 3 upgrade. In that past logcheck log, there are other detectors listed as well, which makes me wonder if something is still stuck with the new Mailman 3 install (or if maybe something needs to be changed in a setting file somewhere): Here is an example of previous log lines: Running detector: <class 'flufl.bounce._detectors.sina.Sina'> Running detector: <class 'flufl.bounce._detectors.llnl.LLNL'> Running detector: <class 'flufl.bounce._detectors.exim.Exim'> Running detector: <class 'flufl.bounce._detectors.qmail.Qmail'> Running detector: <class 'flufl.bounce._detectors.exchange.Exchange'> Running detector: <class 'flufl.bounce._detectors.netscape.Netscape'> Running detector: <class 'flufl.bounce._detectors.dsn.DSN'> Running detector: <class 'flufl.bounce._detectors.caiwireless.Caiwireless'> Running detector: <class 'flufl.bounce._detectors.aol.AOL'> Running detector: <class 'flufl.bounce._detectors.yale.Yale'> Running detector: <class 'flufl.bounce._detectors.smtp32.SMTP32'> Running detector: <class 'flufl.bounce._detectors.groupwise.GroupWise'> Running detector: <class 'flufl.bounce._detectors.simplewarning.SimpleWarning'> Running detector: <class 'flufl.bounce._detectors.microsoft.Microsoft'> Running detector: <class 'flufl.bounce._detectors.postfix.Postfix'> Running detector: <class 'flufl.bounce._detectors.simplematch.SimpleMatch'> Running detector: <class 'flufl.bounce._detectors.yahoo.Yahoo'> Thank you for your time, Andy ----- Web References: [1] https://www.debian.org/News/2022/2022032602 [2] https://mail.python.org/archives/list/mailman-developers@python.org/thread/… [3] https://phabricator.wikimedia.org/T282348 [4] https://mail.python.org/archives/list/mailman-users@python.org/thread/MISUM… [5] https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… [6] https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message… [7] https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… [8] https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/…

Rpsamd greylist configuration for Mailman3
by Prasanth Nair Aug. 3, 2022

Aug. 3, 2022

Hello, I'm in the process of configuring Rspamd with the Mailman3 server. If Rspamd flags a message under 'greylist' and accepts it after the temporary rejection, is there any way mailman can move that message to the moderator's queue? if it is possible, can someone send me the instructions, please? Kind regards, Prasanth Nair

Mailman 3 questions (purge archives, list metrics, and auto discard held messages)
by bob B Aug. 2, 2022

Aug. 2, 2022

Some quick mailman3 questions --Just wanted to check that there is still no way for mailman3 to automatically purge archived emails after a set amount of time? it looks like you have to export the database, purge the messages, then re-import, is this still the only/best way to purge old archived messages? --I noticed on the list info page you have metrics, which is straightforward except for "volume" My volume number is not increasing? What is that counting exactly? --Is there any way to auto discard held messages after x amount of time? I assume not but had a user ask if that was an option. Thanks for the assistance in advance.
