You could try ORF from www.vamsoft.com - I've not used it but apparently
it hooks into Active Directory/LDAP at the "RCPT TO" to validate the
recipient. Another option, though not MS would be a linux/bsd MTA such
as postfix, I use this with an hourly export of the GAL and we reject
around 7000 pieces of mail a week to random/old addresses.

regards,
Paul
