Question

What is that return path for?

Can i Use in this way?

mail($to_address, $subject, $message, $headers, "-f".$return_path );

Where:

$return_path = "C:/www/project/handlebounceemail.php";

Additional:

How to direct the email to a php script? I want to read the email and check for errors.

Answer 1

The $return_path refers to the email address to which undeliverable messages will be sent. This does not refer to a file or URL. So you could use:

$return_path = "[e-mail]";

The next step would be for you to write a script to read the mailbox of the bounces user and do something based on the contents. The exact operations required to do that are dependent on your email system.
