As others have already said: header_checks inspects one header at a time,
not all headers as a whole.
If your mail goes through Postfix only once, you could try prepending
some unique header (e.g. Subject or Message-ID) with the Reply-To
header:
if /^message-id:/
/^message-id:/ PREPEND Reply-To: "Support" <supp...@example.org>
endif
However, that's merely a workaround (and an ugly one at that), not a
real solution.
And please use RFC 2606 domain names instead of some made-up fake domain
that may actually be a real domain belonging to someone else. That's why
the domains in RFC 2606 are reserved after all.
