Since I've wished for the ability to shut these messages off, I'll throw in
my two cents.  My experience here is that most of these are caused by (a) VAX
mail programs bouncing mail because of quota problems, (b) repeated user
error, and (c) those persistent people who I've served out because they
repeatedly post to a list which rejects them, but the messages are too large
to go back through the gateway from whence they came.
 
(B) and (C) seem to me to constitute errant users, not errant software.  (A)
raises a point which I've been wondering about:  is there anything in any
spec which makes the VAX mail system non-compliant?  I get enough of these
silly quota errors to find them irritating.
 
Perhaps I'm just irritable because of Mister Nuttall, definitely a Class (A)
errant user.
