Correct. The design of SMTP is such that, for all practical purposes,
the MTA must accept and queue the message before attempting local
This is very firmly what I have understood for a long time. So, I'm
puzzled at just how procmail returning a 75 could possibly cause the remote
host to requeue a message _it_no_longer_has_in_the_queue_ (seeing as at the
time of the SMTP transaction, sendmail said "I've got it, thanks", and
handed back the session/messageid).
