With all due respect, a moderator didn't think my posts were a
waste and this is a moderated list.  God forbid anyone ask a
question that someone else knows the answer to in case that
wastes the knowledgeable person's time.  I do not consider
the average plug user's time worthless.

I hope someone can offer pointers on using regular 
expression checks to trigger greylisting.  I can't 
do blanket greylisting, some servers that are legit 
don't retry.  My smtp partner will become very 
displeased and accuse me of losing important email
to him.
