Not if you turn on receiver_verify. Verification of an address consists
of running it throught the directors and routers in "verify" mode.
Recipients are verified as soon as the RCPT TO command is received in
the SMTP dialogue.
In other words, the directors/routers fulfil two different, but related
functions. In their normal use they determine where to send the message
for a given recipient. In their "verify" mode they are used to check
whether senders or recipients are valid addresses. In simple cases,
these involve exactly the same work, but you can make them different by
means of various flags (verify, verify_only, fail_verify).

What's wrong with
recipients_reject_except = postmaster@*
