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. More info here:
