I'm having trouble with a Mailman install which I maintain for a charity (2.1.39_1 on FreeBSD 12.3-p5)
In diagnosing a DMARC "FAIL" reported in Gmail I notice that some settings are having absolutely no effect:
from_is_list dmarc_moderation_action dmarc_quarantine_moderation_action dmarc_none_moderation_action
So in my testing today, at no point have I been able to get Mailman to "Munge From" or "Wrap Message" in any way.
Other nearby settings work, so I am able to change the config; it's the correct list etc. I've also tried re-starting. Logs in /usr/local/mailman/log aren't showing any errors or hints.
As some feedback, an FAQ [*] mentions ALLOW_FROM_IS_LIST; setting this has no impact, not suprising as the source code doesn't seem to mention this string anyway. Reading more carefully, I can see this doesn't apply to the current version; perhaps someone with Wiki access might consider the manner it's written, whilst technically correct, is a little backward/confusing, or removing old information.
