there's no bandwidth savings from silently dropping the message

I thought I had already participated in beating this dead horse
sufficiently in multiple threads in multiple forums on multiple
occasions. Maybe I am in your killfile or something. If I post again on
this topic, I certainly will deserve to be.
Let me ask you this simple question:
If you know at close of DATA whether you are going to actually perform
final delivery, what does it cost you to follow standards and issue a
550 instead of a 220 and discard it?
If you use a 550, a real live person sending an email that somehow gets
FP will actually benefit.
I am with Suresh on this, just like in the past threads. Search the archive.
