Although I've only had IronPort for a few days, it appears to be quite brilliant! I've received no spam whatever since being switched to IronPort....presumably all my previous spam is now in the barred group. I've had no false positives....I used to experience a number of those. For interest, my Spam Setting is at No 1. I note that PlusNet has researched a number of spam management platforms, the result is a great credit to the team and a great benefit to the PlusNet user. Many thanks!
