if deliver was a perfect little program, yes.  but it isn't.  if lmtpd
isn't answering, deliver treats this as a PERMANENT failure.  also, the
reason lmtpd gives for rejecting a message is not kept, deliver picks a
reason out of its hat instead, leading to bounces which are very
confusing to the users.

since there is so little incentive to use deliver, no one has bothered
to fix these bugs.  (Cyrus 2.2 may be better.)
