This is a work-around for "reject_non_fqdn_recipient" which applies
to all addresses except "postmaster". Bottom-line "postmaster" is
exempt from restriction processing. Explicit submission support
was added to Postfix long after the basic foundations were laid.
Yes, the exemption for "postmaster" is really for inbound mail,
not submission, but there is no code at present to special-case
the behaviour.
