Like I said, I'm not at all sure it does. But I'm told that there should be an 
SMTP reverse proxy running on the firewall to protect the full server from 
"delivery attempts
to never-existed addresses (with a subclass for never-existed addresses
that match the format(s) of your generated Message-IDs), attempts to use
VRFY and EXPN, attempts to use RCPT that are aborted (likely indicate
spam-supporting abusers doing external SAV), and so on".

Just trying to decide whether I want to do it, and I think I've been convinced 
on this list that I don't.

Thanks all...
