This is from the document mail$archives:[info-pmas]info-pmas.2006-08
rver.
When a RCPT TO: is received, it's handed to the backend server. If it
rejects it, PTSMTP sends the rejection reply back to the client and
the message is never seen by PMAS (or PMDF).
So using PMAS PTSMTP wouldn't change anything regarding those messages
for bad usernames---they'd still be rejected during the SMTP session
just as they are for you now.

Some day I need to do that, too.

I don't think our number is that high just yet, but I'm daily deleting
close to 1,000 bounces to Postmaster because of bad usernames.

We started using vFastScan a few years ago. Without some way of putting
the virus defs into memory our Alpha would bog down in less than an hour
and never catch up again, not even over the weekend. Not sure which
method is cheaper or better, but vFastScan has been working for us, and
we're still on the older version.
