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 = "[email protected]";

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.
