[the second one should be check_mumble_ns_access, for blocking mail
by their name server name or IP address]

The prime directive for Postfix is to deliver mail reliably without
sucking from a performance or human interface point of view, and
without granting unnecessary privileges to random strangers.
The prime directive is not to force other systems or operators to
abide by RFCs. People who have enough time on their hands can write
a suitable plugin for the policy protocol or Milter interface.
