You can download undelivered emails to your phpList project using bounce processing. How do you deal with downloaded emails? No idea, let’s take a look on advance bounce management that allows you to sort out bounce emails. Every returned email message has error code that is returned by the MTA (Mail Transfer Agent). Further, you can review returned message email header and it contains all the information along error code.

First thing first, enable advanced bounce handling by copying below code in config.php file.

define('USE_ADVANCED_BOUNCEHANDLING',1);
