	If you're a transit MTA, then whether or not VERP was used to 
create the envelope sender address should not matter -- you should 
just pass the string you were given.  If you're the target MTA, you 
don't need to worry about VERP because it's only used on the sender 
address, not the recipient -- so plus detail is not there.

	The VERP stuff only comes into play if there is a bounce that is 
generated, and then the only MTA that needs to do anything with it is 
the original sending system.  Even then, the MTA doesn't actually do 
anything with it, it just passes everything to Mailman.
