在php或codeigniter中设置邮件传递收件人

Question

I am using CodeIgniter to send mass mails to people on a school account. When the email returns "Mail Delivery Error", I want the error email to be sent to the school, and not to the $from address.

The sending and receiving of emails works fine, but is there a way for Codeigniter or PHP to catch the mail delivery error and send it to another email address?

Something like:

CodeIgniter - $this -> email -> mail_delivery

or PHP - mail_delivery_error()

Answer 1

The bounces are handled by the return path header of the mail. You can modify the header to point to the right location. This answer explains return path in detail. This answer explains how to do it in PHP
