note 19414 modified in function.mail by derick

Another followup to the 5th parameter and Return-Path. In an earlier note it was quoted from the man pages of sendmail, that if the Errors-To header is sent, then it will be used as Return-Path instead of the -f parameters value. That did not work for me... The Errors-To header seems obsolete... The Return-Path will only work (for me) when set by the 5th parameter as "-f$EMAIL_FROM". Otherwise it'll try to return errors to nobody@$server. --was-- Another followup to the 5th parameter and Return-Path.

Otherwise it'll try to return errors to nobody@$server. BUT... When the -f parameter is used, you'll get an additional header X-authentication-warning, which doesn't look very nice in your mails, but the Return-Path will work... Hope it could help somebody or at least my self. http://www.php.net/manual/en/function.mail.php
