Thanks for your interest in this topic. The part of mail.log and the

This particular example has been marked as spam, but the sender's
information didn't play a role in this classification.

Why doesn't sendmail reject it like it does here? (..) .. Domain name required

I cannot afford rejecting all null senders as those could be
legitimate Delivery Status Notification messages.

What I am looking is a pattern for line:
MAIL FROM:<"do not mock at your poetenncy - bujyj vjaqrra ppislls"<>>
while I want to allow:
MAIL FROM:<>

So any ideas are appreciated whether on sendmail or spamassassin level.


Sounds like you have:

FEATURE(`accept_unresolvable_domains')dnl

Set in your sendmail.mc file; dnl it and Sendmail won't accept that as a valid sender:

MAIL FROM: <"do not mock at your poetenncy - bujyj vjaqrra ppislls" <>>
553 5.5.4 <"do not mock at your poetenncy - bujyj vjaqrra ppislls" <>>... Domain name required for sender address

Steve.
