If you use exim, check out:
http://marc.merlins.org/linux/exim/sa.html
It allows SA scanning at the MTA level and includes a GreyListing
pluging for SA3. You should be able to configure exim to only allow it for
certain recipient addreses but you'd have to do that research yourself.

Subject: Greylisting
Hi,
Is there any kind of plugin or patch for spamassassin that will allow me to
selectively turn on GREYLISTing for certain user accounts?
When I say greylist I mean: All e-mail coming into them is bounced with a
temporary error the first time, and then accepted the second
time. If accepted (ie sent a second time) it is then put in a
database of valid e-mail accounts for the next 60 days (or until another
e-mail is received).
This has the potential to greatly reduce spam since spammers don't usually
try to send mail again, however I don't want to roll this out on a server
wide setup, but rather would like to do it on a per-user basis.
Any thoughts?
