I use SpamCop to report my spam. I use the SpamHaus RBL as a first line of defense then I use SpamAssassin to catch the rest of the spam coming to my server.
Am I wasting my time? Should I just delete low-scoring spam and let the honeypots harvest and report to the various RBLs, or should I keep reporting spam via SpamCop (which wastes a lot of my time). Steve
