Or the sender might not retry for whatever time they have configured for
these things. Or this mail has a multitude of recipients (domains in your
case) and at each (retry) time only one of them gets delivered.
Resulting in very noticeable delivery delays which your customers and/or
the senders will likely complain about.
Until we get a RFC approved mechanism to reject mails on a per recipient
basis AFTER the SMTP DATA phase there are no really "good" solutions to
this problem unfortunately.
Technically perfectly fine and valid answer by Jeremy, it's just a pet
peeve of mine and thus me piping up. ^^
