Hi everyone As we all certainly know, this ML since a few months rewrites all "From:" headers to "X Y via ffmpeg-devel " We changed this because neither me nor timo nor rather unhelpfull AI could fix the bounce & dmarc issue 33 @outlook and 19 @hotmail subscribers got deleted on october 8th because their accounts where disabled from earlier bounces and they did not re-enable their accounts. Other mailing lists from other projects seem to survive without universal rewriting. Should we try to switch this list back to only rewrite the addresses that need it ? mailman3 has a list where we can manually add domains which need it hotmail.com and outlook.com both have a DMARC policy of none so they would not automatically fall under DMARC mitigations and it seems noone added them to the mailman3 list nor was outlook in the postfix list we had from mailman2 days Both me and timo want to try reducing the from rewriting again. We seem to disagree a bit on if we try with the mailman3 manual DMARC list empty first or starting with outlook and all entries from the sender_canonical rewrite list. Are there any people reading this, who have some information / experiencees they can share about mailman3 DMARC settings ? (so we can benefit of your experience and can skip some trial and error :) What do people think ? any other thing we are missing ? PS: we now have a DMARC setup, ARC signing and mailman3 thx -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Modern terrorism, a quick summary: Need oil, start war with country that has oil, kill hundread thousand in war.
