Then these are relay domains not virtual alias domains, unless you
rewrite the address to an internal domain specific to Exchange in transit.

Which is the wrong thing to do, since for relay domains, the validation
table is "relay_recipient_maps" not "local_recipient_maps". You can use
LDAP and skip the need to generate flat file tables, unless you want
to protect AD from the query load...

Because you are not setting relay_recipient_maps.
