Normally LISTSERV will process such messages automatically and take care of auto-deleions by itself. Only if LISTSERV cannot understand the error message will it be forwarded to the List Owner for human interpretation/action. If you desire to process all errors manually, then you can turn off auto-deletion (it is turned on by default) and process all error manually.
