I have some hundred undeliverable mails in my POP-Account, but at the MLM-statistic, they are not shown. Everthing else works fine with the stats (Opened, Unsubscribed, clicked Links ...) but unfortunately no undelverable mails appere.
Eventually the reason is to find here: I use two differend E-Mails for my Newsletters. "Noreply@" ist the Errors ans sendback-mail, "newsletter@" is the answer-mail.
