I have noticed that "relay_domains" is accompanied with
"relay_recipient_maps" in the STANDARD_CONFIGURATION. For sure, the
"last relay" must know the full and exact list of valid recipients, or
else the whole system will become an ugly scattermail source. Yes, I
know also "reject_unverified_recipient" workaround and use it with
MS-Exchange now instead of proper LDAP lookups to Active Directory.

Possibly, just an other form of same question. What is the root
difference between "relay_recipient_maps" and "virtual_alias_maps"? As
to me, the difference seems to be cosmetic.
