Loops back to myself
by David Krantz Jan. 12, 2024

Jan. 12, 2024

Hi, I have a problem with my Mailman 3-setup. The symptom is that postfix rejects non-existing addresses for my list domains with <adr(a)example.com>: mail for example.com loops back to myself What I guess happens happens is that postfix for some reason accepts the mail as it is for a relay domain and finds that it is not deliverable locally as the address does not exist locally and then tries to relay it on to the appropriate MX server, which is itself and then fails and generates a bounce message. This is a bit annoying as I have set up postfix to only accept valid addresses. I have set the transport_maps, local_recipient_maps and relay_domains to the files generated by MM3. I run an older version of MM3 (3.0) but prefer to fix this without upgrading as upgrading is a relatively big undertaking. This is mostly a backscatter problem for spam I guess. Any ideas of very simple and easy to forget things that I've probably missed? Cheers // David

Archive import fails: "IndexError: list index out of range"
by Johannes Rohr Jan. 6, 2024

Jan. 6, 2024

I am now importing the archives of my old mailman2 installation. Unfortunately, with some of the larger and older lists, import fails halfway through, with an exception, the last message of which is IndexError: list index out of range Below is an example. This means that the last few years are missing from the archive in several lists. Are there any suggestions what I could do to still get them importet? Thanks!

Programmatically modify Thread-Topic *before* message is sent out the door?
by Thomas Ward Jan. 3, 2024

Jan. 3, 2024

We use a custom plugin to do numeric thread stamping, which has been working well in the code system. However, it was discovered by Microsoft that Microsoft Outlook and OWA prioritize the Thread-Topic header over the Subject header, which results in the oddness we've experienced in MS365 clients in testing. During our tasks though a custom handler goes through during the pipeline and modifies the Subject field accordingly, adding a thread tag to it. While this is 'fragile' it does work; the only problem is that Thread-Topic doesn't get altered. Programmatically, how would we alter the Thread-Topic during the handler's processing to prepend the corresponding prefix/tag so that when the message actually goes out the door it is properly sending with the modified Thread-Topic?

Editing the "example.org" site
by Stephen J. Turnbull Jan. 3, 2024

Jan. 3, 2024

Hi all, I don't know how many people will need this, but I just realized that you can edit Django's SITE 1 and (probably, 100% untested but I'm going on the clock so want to get this done quick :-) use that. When you add your first domain, there's a link in that page (not a button, a link!) to edit the domain list. Then you can click on the link to "example.org" in the list, and edit both display name (which I assumed) and the domain name. Maybe I'm just slow, but I've been adding SITE 2 = "Whatever site <whatever.tld>" the whole time. :-) But then you have to edit the SITE = 1 statement in settings.py (which I often forget and hilarity ensues). Of course adding a web site and editing settings.py (which you have to do anyway for other variables) works too, but this seems cleaner to me. Steve

Can't edit lists anymore: "Something went wrong HTTP Error 404"
by Nils Dec. 30, 2023

Dec. 30, 2023

When I try to edit any list at "postorius/lists/LISTNAME.SUBDOMAIN.DOMAIN.TLD/", I get this error. The lists are displayed correctly at "postorius/lists/". Selecting any of those lists leads to that error. First step of creating a new list is possible but I get the same error right after the creation of the new list.

"From address" for list moderation notification

Dec. 30, 2023

Hi Mailman Group, I noticed that the from address for list moderation notifications are coming from a certain user address. May you please help me figure out where to change this? In this example, I would like to change the From address "listadmin(a)domain.com" ================================================================ -----Original Message----- From: Admin <listadmin(a)domain.com> Sent: Thursday, December 28, 2023 12:00 AM To: dummy-list <dummy-list(a)domainx.com> Subject: The dummy-list(a)domainx.com list has 2 moderation requests waiting.

Again, after systemupgrade the log file in /var/log/mailman was owned by list:list instead of mailman:mailman and starting failed for this reason [support request]
by Wikinaut Dec. 28, 2023

Dec. 28, 2023

I made for a repeated time (after system update and/or system reboot) the experience,that my mailman3 installation fails to start because of permission error to write the log file. For some unknown reason, an empty file /var/og/mailman/mailman.log was apparently owned by list:list. I deleted that file and mailman3 core could now be started. The start problem i solved. I asked myself and you, how can this happen for many times? Has anyone an idea what the reason could be? There is still a user list from a previous mailman3 installation, where I assigned the (former user for mailman2), but I suppose the problem is a different problem than a simple user definition. The other log files are always correctly assigned to mailman:mailman <pre> -rw-rw---- 1 mailman mailman 7487 Dec 22 18:21 bounce.log 0 -rw-rw---- 1 mailman mailman 0 Oct 8 22:46 debug.log 4 -rw-rw---- 1 mailman mailman 1909 Dec 24 09:10 mailman.log 57448 -rw-rw---- 1 mailman mailman 58820418 Dec 24 09:00 mailman.log.1 108 -rw-rw---- 1 mailman mailman 108407 Oct 24 12:18 mailman.log.2.gz 0 -rw-rw---- 1 mailman mailman 0 Oct 8 22:46 plugins.log 232 -rw-rw---- 1 mailman mailman 229585 Dec 24 09:10 smtp.log 4 drwxr-xr-x 2 mailman mailman 4096 Oct 20 00:00 <font color="#729FCF"><b>web</b></font> </pre>

subscribing to a list from a WordPress site
by Johannes Rohr Dec. 25, 2023

Dec. 25, 2023

Dear all, is there a wordpress plugin/widget allowing visitors to subscribe to a mailman3 hosted mailing list? Else, what is the most convenient way? Sure, I could just link to the maiman site, but since joining a list is as easy as sending mail to LISTNAME-join, there should be a simple way to impement this. What is the best practice? Cheers, Johannes
