You can precisely define filtering methods and forget about junk e-mail messages clogging your inbox. It supports all popular e-mail clients (e.g. Outlook Express, Outlook, Eudora, The Bat! etc.). It's ready to use immediately after quick and easy installation. It has got a quarantine option that prevents your mail from being lost.
