I think I'm having an unusual problem with Majordomo. Someone from delphi
is sending mail to majordom which it can't understand. Instead of
bouncing an error of some sort back to the offending delphi user, a
message which looks like this goes back to email@example.com:
Received: from vector.casti.com by delphi.com (PMDF V4.2-11 #6311) id

END OF COMMANDS
I've looked through my sendmail logs, and I do find some suspicious-looking
Feb 21 18:20:01 vector sendmail: AA04292: from=<>, size=6453,
class=0, received from delphi.com (18.104.22.168)
Followed almost immediately by mail back to firstname.lastname@example.org.
First, and most obviously, how can I throw those messages away instead of
sending them back to email@example.com?
Second, why are they going to postmaster@delphi and not postmaster locally?
