You could just use "sub filter_end" to insert a new HTML part that comprises your header (assuming the content also contained HTML). Easier than modifying the existing HTML to add a header. However... make doubly sure to *ONLY* do this on mails that originate locally, from your own domain, and never for any mails in transit, as you'll break DKIM signatures on the body. Don't just look at originating IP, look at the From: address too. And best of all, as the previous posting suggested... don't do this at all. It will likely just get your domain blocked, either explicitly or implicitly as spam-detection algorithms get too many of the same HTML headers, and they start treating it as spam. So, just... no. > <snark>Also, please let us know who this is, so the rest of us can block > their mail...</snark> -- Jan-Pieter Cornet <[email protected]> Systeembeheer XS4ALL Internet bv www.xs4all.nl
