An LDAP lookup against Active Directory is the only sensible way pre Exch2003. Peter Savitch posted some code to the Exim wiki for this: http://wiki.exim.org/MsExchangeAddressVerification The filter option is fine for Exch2003, but Exch2007 users will now need a 64bit "Edge Transport Server" to do this, and it has to be run on a separate/dedicated box with 2GB ram according to the docs.
