Because of a domain move we're doing, we're trying to add a reply-to header in postfix when no reply-to header is already present. The rule we're using is:
!/^Reply-To/ prepend Reply-To: "Support" <supp...@ourdomain.org> However, since the check is being applied to each header line we get a bunch of reply-to's prepended instead of just one. Is there a regex we can use to say: If no reply-to header exists anywhere in the headers then prepend one reply-to header Thanks, Todd -- View this message in context: http://old.nabble.com/Adding-a-reply-to-header-when-none-is-present-tp30429730p30429730.html Sent from the Postfix mailing list archive at Nabble.com.
