Note that Tom's suggestion doesn't quite work as advertised.
The configuration parameters:
- mydestination
- virtual_alias_domains
- virtual_mailbox_domains
- relay_domains
Are mainly processed in the trivial_rewrite(8) process, which rewrites
addresses to standard form and classifies them by address class. The
smtpd(8) service determines whether to accept a recipient, or not, based
on the address class returned by trivial-rewrite(8).
Therefore, master.cf overrides of "mydestination", ... in smtpd(8) don't
work the way one might naïvely expect.
So to limit which domains you accept to be a subset of the local
domains, you need actual access(5) tables, not the suggested parameter
overrides.
