Email Bounce

[Anon]

No matter how I slice it, I can not ssem to get a bounce to go to either the email sender or anyother address I try listing in the header. Why do emails from php3 & 4 not bounce appropriatly?

Here is a simple test I used:

<?

$recipient = "[e-mail]";
$subject = "A bounce test";
$message = "This is a bounce test";
$bounced = "[e-mail]";
$headers = "From: [e-mail]\r\n";
$headers .= "Errors-To: ".$bounced."\r\n";
$headers .= "Return-Path: ".$bounced."\r\n";
$headers .= "Content-Type: text/html; charset=iso-8859-1\n"; // Mime type

mail($recipient, $subject, $message, $headers);

emails go out just fine but if it is a bounce, the return message always goes to the server root user, never to a user I specify or the sender. All I really want is the email to bounce back to to the sender. I've looked at the php.ini, and the sendmail.cf. I see no abnormalities, although I find sendmail a little obtuse. What is going on? How can I fix this?

There is another header in the mail file, it's called from (all lowercase) this header can't be set by PHP's mail() (at least not for sendmail).

You'll have to write your own function that calls sendmail directly and passes it the -f switch with the email address you want bounces to go to. Unfortunatly you need to have sendmail set up to allow you to do this, since it's a very bad thing to have set up (helps spammers hide).
