sendmail returnpath

[nogeekyet]

My php email script is working. However, I would like to capture any bounce-backs. My code looks like this:

		$to      = $data[2];
		$subject = "something";
		$message = "Dear $data[1],\n
					etc. etc. etc";
		$headers = 'From: [e-mail]' . "\r\n" .
		        'X-Mailer: PHP/' . phpversion();
		$mailsend = mail($to, $subject, $message, $headers);
		if (!$mailsend) {
		        echo "<h1>mail NOT sent</h1>";
		   };

What does the returnpath look like and where does it go? If there is such a thing.

Thanks for your help.

Pretty sure it's Return-Path, e.g.:

$headers = 'From: [e-mail]' . "\r\n" . 
        'Return-Path: [e-mail]' . "\r\n" .
        'Reply-To: [e-mail]' . "\r\n" .
                'X-Mailer: PHP/' . phpversion(); 

Be aware that some M.T.A.'s will totally ignore Return-PATH, though. There's a lot of discussion about this out there.

Mail servers might not even bother to send bounce messages. There are tons of them out there with bazillions of different configurations.

I would strongly recommend that you filter/validate your $data array or your script might be vulnerable to abuse, in which case you'll eventually have problems sending mail.

You might want to use [man]filter_var[/man] on $data[2], for instance.
