This e-mail application aims to stop spam by letting you bounce e-mails from your POP3 server before you download them, fooling spammers into thinking your address isn't valid. You can add bounced senders to a personal blacklist that will bounce all future attempts automatically. If the spammer uses a program that purges bounced addresses, over time this should get your address off the list. Hotmail access is available only in the Pro edition of MailWasher, as is protection of multiple accounts. MailWasher Free works best for people with a single POP3 account, or as an extended demo for those who are considering buying the Pro version.
