Version: 1.5.4 (using KDE 3.1.4) Installed from: (testing/unstable) Compiler: gcc version 3.3.2 20030908 (Debian prerelease) OS: Linux (i686) release 2.6.0-test9 There's an option of adding custom email headers for all emails sent; but if one wants to send a custom email header only for some of the emails, such an option should be provided in the compose mail window. This will especially be useful for the Mail-Followup-To: header (http://cr.yp.to/proto/replyto.html). btw, I don't think kmail supports mail-followup-to. Any plans on incorporating support for this?
KMail 1.6 will respect the Mail-Followup-To header on replies.
