Or use "reject_unverified_recipient", which uses a cache of previous decisions so it won't hammer the mailbox server.
A clarification: Does the cache of "reject_unverified_recipient" decisions include the result of "relay_recipient_maps" lookups?
This might be esp. useful in case the "relay_recipient_maps" setting is blank, in which case the final destination server(s) is (are) queried for the recipient (and should reply with a 550 if the recipient does not exist).
Thanks, Nick
