MailWasher is a program you run on your PC to help you get rid of spam and viruses in your e-mail, before running your normal emailer to get your email.

MailWasher allows you to preview all aspects of your e-mail on the server before you download it to your computer, thus protecting you from spam, viruses, phishing attacks, and other nuisances. You can then delete unwanted e-mail before it gets to you.

Other features help identify and protect you against viruses and worms. Also included are comprehensive, customizable filters, use of friends list, and blacklist to stop spammers.
