The Reply-path: you want to change is not a normal header, so you can cross off the idea of fixing it with the 4th arg to mail(). If you are using current PHP, there is yet another bonus argument, the 5th one, for this specific purpose, documented in the manual: http://php.net/mail If you are NOT using a version of PHP that has that 5th arg, then you could maybe use ini_set on the sendmail_path to add the -f there. (see man mail). That, however, would require that the user PHP runs as, which is what Apache runs as, be a trusted user in sendmail.cf, which your webhost may or may not have decided is a Good Idea, based on how much they trust their clients. Going farther afield, you could attempt to find an SMTP host/server/setup that would allow you to set these values to what you want -- I *think* that's do-able... I never had to go that far, personally, so can't be certain. You may also want to convince the recipients to white-list your address, so that the From/Reply-path/etc are all irrelevant for spam filtering. This has the advantage of being a long-term solution, for any reasonable implementation of spam-filtering that allows whitelisting by the recipient, no matter what spam-filtering "rules" are brought to bear in the future. -- Like Music? http://l-i-e.com/artists.htm --------------------------------- All new Yahoo!
