There are a number of good spam prevention solutions out there but unfortunately I couldn’t use any of them for a few of my accounts – many of them are for Outlook only at the moment and I prefer Eudora. Others require your ISP to sign up. But at last I found Mailwasher, which lets me check my POP3 email and “cleanse” it quickly and easily either by referring to one or more known spammer black lists (including ORDB and SpamCop) or by referring to rules I set up. I recently tested it against 96 spams and got two false positives (only listed as “possible” and “probable” spam) and three real spams let through. That’s good enough for me – especially as Mailwasher is free!
