Uncaught runner exception

by Wolfgang Bock

Hello, I need your help. I got a "Uncaught runner exception: invalid literal for int() with base 10:" Referring to a discussion in Sept. 2019 with Manos Pitsidianakis "Cannot connect to SMTP server localhost on port 25" I did following: stop both postfix and mailman 3 services. Deleted all files in the /var/lib/mailman3/queue directories. Restarted both services. With following configurations: (extracts): /etc/mailman3/mailman.cfg [mta] incoming: mailman.mta.postfix.LMTP outgoing: mailman.mta.deliver.deliver smtp_host: Tried with 127.0.0.1/localhost/server ip or FQDN=servername smtp_port: (got a "cannot connect to SMTP Server on port 25") so I let this item empty ... smtp_user: smtp_pass: lmtp_host: 127.0.0.1 lmtp_port: 8024 configuration: python:mailman.config.postfix /var/log/postfix/mail.info Apr 6 00:02:22 ... postfix/postfix-script[31407]: starting the Postfix mail system Apr 6 00:02:22 ... postfix/master[31409]: daemon started -- version 3.4.8, configuration /etc/postfix Apr 6 00:03:09 ... postfix/smtpd[31462]: connect from mout-p-103.mailbox.org[80.241.56.161] Apr 6 00:03:09 ... policyd-spf[31468]: prepend Received-SPF: Pass (mailfrom) identity=mailfrom; client-ip=80.241.56.161; helo=mout-p-103.mailbox.org; envelope-from=[mail address]; receiver=<UNKNOWN> Apr 6 00:03:09 ... postfix/smtpd[31462]: D29FE138023E: client=mout-p-103.mailbox.org[80.241.56.161] Apr 6 00:03:09 ... postfix/cleanup[31471]: D29FE138023E: message-id=<6a504834-123a-60f6-3a0e-494623b74523(a)mailbox.org> Apr 6 00:03:25 ... postfix/qmgr[31411]: D29FE138023E: from=<[mail address]>, size=2811, nrcpt=1 (queue active) Apr 6 00:03:25 ... postfix/smtpd[31462]: disconnect from mout-p-103.mailbox.org[80.241.56.161] ehlo=2 starttls=1 mail=1 rcpt=1 data=1 quit=1 commands=7 Apr 6 00:03:25 ... postfix/lmtp[31481]: D29FE138023E: to=<[list address]>, relay=127.0.0.1[127.0.0.1]:8024, delay=16, delays=16/0.01/0/0.1, dsn=2.0.0, status=sent (250 Ok) Apr 6 00:03:25 ... postfix/qmgr[31411]: D29FE138023E: removed /var/log/mailman3/mailman.log Apr 06 00:02:12 2020 (31148) Master started Apr 06 00:02:13 2020 (31158) rest runner started.

I *think* you are saying to remove the EMAIL_USE_TLS stuff and also move to another port (maybe 587), but I am not sure. Also, the reason I added the TLS in the first place was that I was getting errors without it. And I am unclear why the cert / private key pair do not work for Django when they do work OK for Postfix, Nginx, and Dovecot.

I don't understand how any lists' posts get delivered at all with that. If it's postfix it's possible that the connection pool is exhausted intermittently (but that wouldn't explain why it's consistently impossible to post to a subset of lists). You can specify that connections from the loopback interfaces are less restricted. That might help. > Even after changing the smtp_host in mailman.cfg this error appears > randomly.

Hi Mark, >That's a misleading message. It's been improved by https://gitlab.com/mailman/mailman/-/merge_requests/1362, however usually the underlying issue is inability to access a header or footer template when decorating the message. This in turn is most likely >caused by some template(s) in Mailman's var/templates/ directory being owned by `root` or some other non-mailman user and not readable by the Mailman user which in turn most likely results from running `mailman import21` as root. You are my hero! After "patching" the outgoing.py file with the error messages I got Aug 06 09:52:51 2025 (443278) Cannot connect to SMTP server 127.0.0.1 on port 25: HTTPSConnectionPool(host='lists.example.com', port=443): Max retries exceeded with url: /postorius/api/templates/list/hpc-admintreffen-info.lists.example.com/list:member:regular:footer (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1006)'))) And was shocked. Why is there an SSL Certificate Error? Why can't python requests verify the certificate? So I googled a bit and found, that we can fix this be editing the cacert.pem of certifi. I did, but the error was still there. So I checked my https VHost (Apache btw) and there was a wrong chain in it. Oof. An error, that a browser does not see, but any ssl client. I fixed it and boom - everything works again.

Trying to set up mailman3 on my mail server

by Shawn Heisey

I'm having a lot of trouble with trying to set up mailman3 on my mail server. It's on an AWS instance, running Ubuntu 20.04 LTS. All software is installed from Ubuntu packages. Mailman version is 3.2.2. The problem I am trying to troubleshoot first is how this can be happening: Oct 14 11:27:26 2021 (2341) ACCEPT: <f36e1ed0-9d25-b661-9c94-4ce999f6d5fd(a)elyograg.org> Oct 14 11:27:27 2021 (2344) Cannot connect to SMTP server 127.0.0.1 on port 25 From the shell, I can "telnet localhost 25" successfully, even as the "list" user. Apparmor is disabled. The UFW firewall is enabled, which allows all traffic on the loopback interface. I disabled ipv6 at the kernel level, but had the same problem with ipv6 enabled, so I don't think ipv6 is related at all. I do not see any connections in the postfix log that correspond to the mailman connection error. From a fresh install of mailman, I created two mailing lists. Once upon a time I had those lists active on a Debian 6 machine running mailman 2.1.13 ... I copied the mailing list config from that machine over and used the "import21" facility to import the configuration into the new mailman3 install. That worked without error and I can see the lists and their members with the "mailman" command. I found instructions for integration with postfix, and added the required three config lines to the postfix config. When I try to send a message to the list, I get what I pasted above in the mailman log. I think that means the postfix integration is working, and is forwarding to mailman. I'm hoping somebody can give me some pointers, and if more information is needed for troubleshooting, let me know what is needed. I'm also having trouble with the web UI ... I thought I had found what to do with Apache, but it's having problems and I do not know what to do so it works. The UI is not super important right now, I'd like to get the lists working first. I first tried to get help on the IRC channel, but that appears to be a dead end. I did give it several hours. Thanks, Shawn

While this is always true for mailman-core, in some configurations the mailman-web files are also inside the ./var/ tree, and they need to be readable (and, for some, writable) by the process acting as webserver, which may or may not be list:list. In my case (a bit off-piste) I have set mailman-web it up to run as owner=www-data, for example (I forget quite why this was needed now!!).
