Im trying to get my head around this problem that too many valid emails
from the mailing list fail dmarc. Why when other mailing list don't seem
to have the same problem? I see today it says "signature verification
failed", but why? Is there a problem with protonmail's dkim key? Is the
dovecot list altering the message body? Is something wrong on my
server's end?
The example today was an email from @protonmail.ch, and the headers
were:
