cyrus-devel at lists.andrew.cmu.edu does not do DMARC From-mungling

Thu Apr 23 07:53:32 EDT 2020

Hello,

recently on this mailing list (cyrus-devel at lists.andrew.cmu.edu) there were messages From: Anatoli <me at anatoli.ws>.  For
that domain DMARC policy=reject applies.  So the MLM is supposed to mungle the From: domain, but it does not do so.  In
turns the emails from that recepient over the mailing are subject to reject at the final mailboxes.

It is pure accident that I found this out (just seeing replies from Ken to emails which I have not received, more emails
in the online archives, which I have not received; generated DMARC failure reports, which were sent nowhere, as the
DMARC report has no rua= and ruf= tags).  I can offer mailing list hosting at @lists.aegee.org with DMARC mungling for
free.
