Adding to my 1/19/2003 review on this great application. The seemingly small point update to 2.1.1 brings a substantial increase in speed. I have not clocked it but filtering is now 5 to 10 times faster. This is with approx. 2500 filters on a modern G4 machine.

One suggestion to others, and maybe the developer, is to place a link (drag-n-drop the icon) in the Dock to the POPMonitor Log folder. This gives an easy way to check for "false positives"; and the logs' file size gives a crude Spam-O-Meter(TM).
