PHP class to help webmasters handle bounce-back, feedback loop and ARF mails in standard DSN (Delivery Status Notification, RFC-1894). It checks your IMAP inbox or eml files and delete or move all bounced emails. If a bounce is malformed, it tries to extract some useful information to parse status.

• PHP >= 5.3.2
• Enable the php_imap extension if you want to use the IMAP open mode.

composer require galata90/php-mail-bounce-handler

And download the code:

composer install # or update

See tests/test.php file sample to help you.
You can use the eml files in the tests/emls folder for testing.
