header_checks = regexp:/etc/postfix/blocks

in main.cf (I'm using blocks rather than header_check, just season to
taste) then blocks contains:

/^From: Jeme A Brelin <jeme at brelin.net>/ REJECT

Mine actually contains more than that, stuff after the REJECT line, but
I don't think we need that here.  You can add stuff after REJECT like
550: I don't like this email address or something similar.

That way, as soon as the mail server says From: Jeme A Brelin
<jeme at brelin.net> your mail server says 550: I don't like this email
address.
