If i properly understand the unmunge term, how to unmunge eg. your latest response? In your message is nothing about original sender (nor in From: nor in Sender: header, nor their X-* forms), except the Reply-To: header, do you mean to switch From: <-> Reply-To:? While i am able to setup a lot of things on my MTA, i consider to do something as switch headers on per-list base as out of (my) interest, as it will be unmanageable soon. In theory (i never tried this) i can setup it in sieve on per-user base, but i afraid to rely on Reply-To: header.

Huh, that is not how i understand the ARC, or it is out of my ARC knowledge. I understand ARC as solution directly for DMARC+ML. But i do not use ARC yet, except its rspamd's checks, thus i can be wrong... regards -- Slavko https://www.slavino.sk
