Archive Issue -- prune_arch doesn't remove detached attachments?
by Ralf Hildebrandt Dec. 22, 2020

Today I issued "prune_arch -l flohmarkt -d 30" and wondered about the immense size of the corresponding archive directory archives/private/flohmarkt du quickly showed me why: # du -s * | sort -n 4 index.html 4 pipermail.pck 84 2020-November.txt 296 2020-December.txt 332 2020-November 460 database 1168 2020-December 17280164 attachments Shouldn't prune_arch also clean out the "attachments" directory?

Google reCAPTCHA blocked by SELinux on Mailman 2.1.29 (CentOS 8)
by Ole.H.Nielsen＠fysik.dtu.dk Dec. 20, 2020

Dec. 20, 2020

I have migrated my old Mailman server to a CentOS 8.3 server containing this Mailman RPM package: mailman-2.1.29-10.module_el8.3.0+548+3169411d.x86_64 I would like to enable Google reCAPTCHA in mm_cfg.py as explained in /usr/lib/mailman/Mailman/Defaults.py with: RECAPTCHA_SITE_KEY = xxx RECAPTCHA_SECRET_KEY = yyy I have created the prerequisite V2 keys on https://www.google.com/recaptcha/admin and restarted the mailman service. The Mailman list page now contains a nice "I'm not a robot" frame as expected. However, when I click "Subscribe", the confirmation page says "[Errno 13] Permission denied” (copied from my memory) and the subscription fails :-( It finally dawned upon me that this could be a SELinux issue, since I naturally want Enforcing mode. If I use "setenforce Permissive" the Mailman error goes away! The command "journalctl -t setroubleshoot" tells me: SELinux is preventing /usr/bin/python2.7 from name_connect access on the tcp_socket port 443. (lines deleted) If you believe that python2.7 should be allowed name_connect access on the port 443 tcp_socket by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'python2' --raw | audit2allow -M my-python2 # semodule -X 300 -i my-python2.pp I can confirm that the Mailman error is fixed by this workaround. Question: Is there a proper way to configure this SELinux access for python2.7, rather than making this workaround? Such a solution should be submitted as a bug report to RedHat/CentOS/Fedora. Thanks a lot, Ole

Manually incrementing bounce counters
by Matthew Pounsett Dec. 18, 2020

Dec. 18, 2020

I occasionally get "Uncaught bounce notifications" where mailman has been unable to figure out which user/list to increment the bounce counters for, but where it's blindingly obvious to me. If it's just one or two bounces I'm happy to leave it alone, but in other cases I'd like to manually trigger the bounce processing lifecycle. Ideally I'd like to be able to just suspend these users as if they had hit the bounce limit for their lists, and let the notification process (and possibly the user's action to unsuspend themselves) take over. Failing that, the next best thing is to manually increment the bounce counter for that list/user combination to trigger suspension that way. Has anyone already got a script around for doing either thing? Failing that, is there some documentation somewhere on the object model that I can use to whip up a `withlist` invocation? The docs on this seem pretty thin. I can't find anything on list.org that describes the methods or variables available for lists or subscribers, or how to access them. The "Site Administrator's Manual" appears to have never actually been written, and the rest of the docs in the Site Administrator's section appear to be FAQs and install manuals, none of which address this (that I can find). The class level documentation returned by pydoc seems like it might be useful here, but there's a lot to wade through since pretty much everything appears to be accessed through the MailList class, and there's no example usage that I've seen so far. I'd prefer to avoid having to go line by line through the code if I can avoid it, so some pointers (to docs or examples I can reverse engineer) would be awesome. Thanks!

Using Mailgun with Mailman
by Jonathan M Dec. 9, 2020

Dec. 9, 2020

I run Mailman 2 on a shared server. Over the years I’ve had occasional deliverability problems owing to spam from other users. In the long run I hope to migrate to Mailman 3, on a Digital Ocean droplet or similar. In the meantime, I’m looking at maybe using an email sending service. Is it possible to use Mailgun (or alternative services) with Mailman 2/3? Mailgun does its own bounce processing and I wonder how that might tie in with Mailman’s. If it is possible, in what circumstances (if any) is it advisable? Thanks for any advice. Best wishes Jonathan Sent from my iPhone

genaliases not generating aliases
by Eva Isaksson Dec. 8, 2020

Dec. 8, 2020

I've been running mailman on an old Ubuntu server that will become defunct in a couple of weeks. Besides of having a new cloud based server (with Ubuntu 20.04.1 LTS), I also need to switch from Sendmail to Postfix. Now, setting up Postfix was not too big a problem, but getting it to work with mailman has been challenging. Particularly, genaliases gives me a traceback like this: root@ardbeg:~# /var/lib/mailman/bin/genaliases Traceback (most recent call last): File "/var/lib/mailman/bin/genaliases", line 124, in <module> main() File "/var/lib/mailman/bin/genaliases", line 118, in main MTA.create(None, quiet=True) File "/var/lib/mailman/Mailman/MTA/Postfix.py", line 336, in create _do_create(mlist, ALIASFILE, _addlist) File "/var/lib/mailman/Mailman/MTA/Postfix.py", line 320, in _do_create func(mlist, fp) File "/var/lib/mailman/Mailman/MTA/Postfix.py", line 113, in _addlist loopaddr = Utils.ParseEmail(Utils.get_site_email(extra='loop'))[0] File "/var/lib/mailman/Mailman/Utils.py", line 799, in get_site_email hostname = mm_cfg.VIRTUAL_HOSTS.get(get_domain(), get_domain()) File "/var/lib/mailman/Mailman/Utils.py", line 794, in get_domain return hostname.lower() AttributeError: 'NoneType' object has no attribute 'lower' I'm getting no alias files in the /var/lib/mailman/data/ directory, and my list addresses are not working: <"|/var/lib/mailman/mail/mailman post test-list"@ardbeg.xxxxxx.net> (expanded from <test-list(a)ardbeg.xxxxxx.net>): unknown user: "|/var/lib/mailman/mail/mailman post test-list" I've spent quite some time checking what might be wrong with my Postfix configuration, and trying to search for previous, similar sounding cases, but I've reached the point of feeling quite clueless. Any help would be really appreciated. - Eva Isaksson <eisaksso(a)gmail.com>
