This can't really be done with MailScanner as it does not involve itself
in the SMTP service at all.<br>
There are already plenty of programs out there which are very good at
doing this (ie. the MTAs) so I don't want to try to write my own.
MailScanner is only involved once the entire message has been collected
and queued.<br><br>

crosspost for those of you who are on the SAtalk list, but I'd be
interested to get your opinions on the concept of "greylisting"
as a spamfighting tool (I apologize also if this has been brought up on
the list before). To summarize, it involves initially rejecting an
SMTP session from an unknown source (this is oversimplifying --
it's rather more that the entire SMTP session is "unfamiliar")
in the expectation that a legitimate SMTP host will try again a short
time later while a spamming host will not.</font><br>
