We switched over to XWall and XWALLFilter some time ago after using Symantec Mail Security. Set up was simple and configuration out of the box stopped more spam than the previous product. Maintenance of our anti-spam system has gone from over an hour every day with many false positives, random unexplained false negatives and upset users to a few minutes every month with no false positives and no spam. Excellent solution for quarter the price - our users are delighted and the boss is happy.
