This smells like a common webserver problem, where the webserver submits email messages that appear to come from rhe web server's UNIX account (www-ser...@example.com). Adding a Reply-To: header is the WRONG solution for that. Instead, specify the correct envelope sender address: /usr/bin/sendmail -f yom...@example.com recipient.... If that is not your problem, read on for more. > Is there a way to add a 'Reply-To' header from the Postfix configuration ? You can use milter-regex to inspect email and add or change headers. You can use Postfix built-in header_checks to PREPEND a header but that will add the header even if the message already has a Reply-To header. /^From: blah@example\.com/ PREPEND: Reply-To: yom...@example.com The example needs to be tweaked to the exact form of your message headers. > I looked in the documentation but could not find anything about > setting such a header, conditionally or otherwise. Yeah. There is nothing about adding REPLY-TO headers. Wietse
