That seems strange, I don't know why the superuser would not be able to see things in the archive that a list owner or member can. > The nondelivery of list mail is more serious than the archive problem, > though. Archiving is separate from delivery. messages can be archived and still fail delivery in the out runner which is what's happening here. The question is why? I suspect you have one or more 'Cannot connect to SMTP server ... on port ...' messages in mailman.log? and I suspect this is a misleading issue in this case caused by an inability to read some file in Mailman's var/templates/lists/<list_id>/en directory. I also suspect the shunted messages are from some prior condition which has possibly been fixed, but I can't be sure without exceptions and tracebacks from mailman.log (should be timestamped the same as the mod time if the shunted file). You can view them with `mailman qfile` and unshunt (reprocess) them with `mailman unshunt`. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[MM3-users] 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.

This is your problem. By default, it should be port 25. Apparently there is no fallback for this in case it's left empty. (I would guess if you commented it out, it *would* fall back to port 25. > Apr 06 00:03:26 2020 (31153) ACCEPT: > <6a504834-123a-60f6-3a0e-494623b74523(a)mailbox.org> > Apr 06 00:03:26 2020 (31156) Uncaught runner exception: invalid literal for > int() with base 10: '' This is saying int() was called with the empty string as argument. > Apr 06 00:03:26 2020 (31156) Traceback (most recent call last): [intermediate frames omitted] > File "/usr/lib/python3/dist-packages/mailman/mta/base.py", line 45, in > __init__ > config.mta.smtp_host, int(config.mta.smtp_port), The call to int() in the line above is getting the empty value from the config file. Changing smtp_port to '25' (or the appropriate value) in the config file will prevent the "Uncaught runner exception". If localhost's smptd is not listening on port 25, as the comment above seems to indicate, you either need to - find out the correct value if smptd is listening on a different port, - enable that daemon if it's not running, or - point smtp_host at a functioning outgoing mail server if localhost is not expected to be a mail server. In the latter two cases you also need to make sure smtp_port is correct for the server you use. There are some other, rarer and more complicated, possibilities, so if your answer is "none of the above", feel free to say so. But check those first, please.

[MM3-users] 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

This list had regular and digest footer templates with 0644 permissions owned by root:root, and there was an exception and traceback for the most recent message in shunt about the permissions issue.

Yes, lots. This might or might not be a different issue. As I mentioned earlier, the most recent message in shunt was from 0000 hours today.

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.

[MM3-users] Migrated from MM2 to MM3, all is well except *one* list

by Scott Courtney

Hello, all I have migrated a multi-list server from MM2 to MM3, on Debian 11, and migrated about half a dozen lists with fairly large archives. Absolutely everything has been working for a couple of months, but I am still unable to get one specific list to send mail to its subscribers. Of course, the first place I started was the logs, but that's the problem -- even with logging turned up, it appears to be failing silently as it connects to the MTA. Here's a summary of the environment: OS: Debian Linux 11, 64-bit, on a virtual machine MTA: Exim 4.94.2 List server: Mailman 3.3.3 (installed from Debian repo) Database: MariaDB 10.5.15 All daemons are running on the same host, and communication is either UNIX socket or loopback network interface, for security. Web server: Apache 2.4.53, with proxy to WSGI per the MM3 setup guide Symptom: There are six lists on the server. All six can accept inbound traffic and will post the messages to the (always private, in this environment) archives. The web interface is working perfectly. Five of the lists also can send out messages to subscribers, but the sixth list cannot send traffic to the MTA, or is not attempting to do so. Tests run so far (all resulting in successful posting to archives, but no outbound mail): * Originate mail from inbound SMTP to the list address. * Originate mail from the web UI as a member/moderator. * Originate mail from the web UI as the site admin (also the list owner). * Originate mail from both inbound SMTP and web UI by multiple users.

I know Exim and Mailman are communicating because all the lists use the same SMTP configuration for Exim and Mailman (i.e., the non-working list is not in any way exceptional). I've done a lot of searching online to find a solution, and I did see that a couple of others had asked about this type of problem, but the only one I found that got a response had an issue that didn't apply in my small environment. Absent any other ideas, I'm going to try inserting some trace logging into the Python code, but I can't figure out what's wrong here. I've even gone to the point of looking at the SQL rows to verify this list is exactly parallel to another working list, except its name and integer ID numbers for various unique auto-increment keys. Any suggestions are appreciated. Thanks!

Please let me know what you think is wrong and how to fix it. Normally it means exactly what is says. Is your MTA (Postfix or ??) running? Can you `telnet localhost 25` successfully? Note that if the message actually says `local host` and not `localhost`, the setting for smtp_host in the [mta] section of mailman.cfg needs to be fixed. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

There's a long thread on this at <https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/…>.

If the prototype archiver is enabled you should see the message in Mailman's var/archives/prototype/<list-id>/new/ directory and if HyperKitty is enabled, in mailman's database in the hyperkitty_email table. > I'm hoping somebody can give me some pointers, and if more information > is needed for troubleshooting, let me know what is needed. If your web UI isn't working, you probably haven't created any templates in Postorius, but import21 will create templates and if you ran import21 as root, you may have created templates and perhaps other things that can't be accessed by the Mailman user (`list` in your case). All Mailman related commands should be run only by the Mailman user. [1] This FAQ says you should be going to Debian/Ubuntu for support. If you've tried that and are not getting help there, I respectfully submit that you should purge the Debian/Ubuntu package and start over from here <https://docs.mailman3.org/en/latest/install/virtualenv.html>. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
