Kurt, I regularly check the Barracuda message log, searching for allowed and white listed messages, with a subject that contains "return". If there are more than a few, I tell the customer they need to change their PW ASAP and I do it for them if it continues another day. Unfortunately, it only takes one outbreak to get blacklisted. Barracuda also has a setting that may help you - go to advanced, then click on "Sender Spoof Protection". I also regularly block the top rate controlled and senders at my core router, as to not allow them to even make it to the Barracuda. If you come up with anything else, please let us know.. The account hacking started being a problem for me too a few months back, but so far these controls seem to be helping a lot.
