Thjanks Wietse and Nikita. I currently use reject_unverified_recipient. There
are two (or maybe three) problems I have with this though: First if an
address hasn't been checked it gives a 4xx while checking on the main
machine - I'm already using gps for greylisting and this is an additional
delay and the machines are even physically next to each other and secondly,
since I use a recipients cache file that will grow and need maintaining. (The
third problem would be having to delete (?) the cache every time users,
aliases, sql, etc are altered on the mail/smtp machine). Could postfix offer
some sort of "verify this address" service / socket / port?
Don't you think that simply using same sql database (and same files,
through nfs) on the relay machine might be a better idea, than copying
information and maintaining cache?
If these machines are physically close, it would be enough fast.
