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?

REST API for list owners/moderators
by mathias＠koerber.org Jan. 3, 2024

Jan. 3, 2024

Does Mailman 3 have an REST API that allows list-owners/moderators to perform list-management functions without having access to the whole server/other lists etc? ie, an API that uses the same credentials as Postorious but allows mass-subscription/un-subscription/membership-export etc and changes to list settings, membership settings (mod etc) via REST or python? The documentation seems to only indicate a single one-admin-user REST API that should not even be accessible from outside?

Message getting shunted with enabling Dmarc replace with list address
by bob B Jan. 3, 2024

Jan. 3, 2024

So we host a mailing list for domain X, the MX record points to us, we are domain y. If we have Dmarc set to "no dmarc mitigations" I can send a message from my email in domain Y and it goes to the list in domain x and is processed and sent out. If I set the dmarc to "replace with list address". the same message gets shunted. I included the logs below Not sure why it is trying to contact publicsuffix.org? ************* /mailman/core/var/logs/mailman.log Jan 02 20:41:50 2024 (29) No cached copy of the public suffix list found Jan 02 20:41:55 2024 (29) Uncaught runner exception: HTTPSConnectionPool(host='publicsuffix.org', port=443): Max retries exceeded with url: /list/public_suffix_list.dat (Caused by ConnectTimeoutError(<urllib3.connection.HTTPSConnection object at 0x7f8b38d318a0>, 'Connection to publicsuffix.org timed out.

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
