mailman break DKIM signature by modifying body
by Peter Münster June 6, 2023

Hi, I'm using mailman 3.3.8. Some messages with attachments from Google users get rejected by spam filters because of invalid DKIM signatures. It seems, that mailman alters some lines in the body. Here an example: Original message: --8<---------------cut here---------------start------------->8--- Lines: 2031 --000000000000f846c505fc494b7a-- --000000000000f846c705fc494b7c Content-Type: application/pdf; [...] Content-Disposition: attachment; [...] --8<---------------cut here---------------end--------------->8--- Altered message: --8<---------------cut here---------------start------------->8--- Lines: 2032 --000000000000f846c505fc494b7a-- --000000000000f846c705fc494b7c Content-Type: application/pdf; [...] Content-Disposition: attachment; [...] --8<---------------cut here---------------end--------------->8--- An empty line is added, and the spaces after the semicolons are removed. Perhaps related to https://gitlab.com/mailman/mailman/-/issues/1079. What could I do please, to prevent such modifications of the body? TIA for any help, -- Peter

Why are "Subscription options" left unselected if I don't manually select them?

When I subscribe to a mailing list, and I don't manually select some of the "Subscription options", they are left unselected when I go back to look at them. I would have thought that if I didn't make a selection, that they would be set to a default option. Or am I wrong? Thanks.

dmarc mitigation debug
by Thomas Krichel June 1, 2023

Hi gang! I have a list with DMARC mitigation action "Replace From: with list address" DMARC Mitigate unconditionally "Yes". But list posts still have the poster's From:, breaking DMARC. How can I debug this? For a start, I looked in my sqlite database. Changes on the web interface list settings seem to be correctly applied to the database. But I don't see a "munge_from" in the fields of a list in the database. -- Written by Thomas Krichel http://openlib.org/home/krichel on his 21181st day.
