Well, protonmail.com has p=quarantine, and Mailman is set to munge >From for both p=quarantine and p=reject, so it should be rewriting From... yet it isn't. Hmm. *sigh* I see. From munging is performed by the SpamDetect pass, and I had manually disabled that pass because – according to a comment I left at the time – it caused Python errors related to Unicode handling. So it never actually took effect. I just re-enabled the pass, and also upgraded Mailman to the tip of the 2.1 branch just in case it fixes the Unicode issue. If it doesn't, the list might start dropping messages fitting whatever pattern was triggering the issue in the past, in which case I'll have to actually find the bug and fix it. For now, though... I just sent a test message from a ProtonMail account, and From rewriting now seems to be working.
