Spam Blocker works with any POP3 email account. It checks your HTML and Text email and removes spam right from the mail server so you never see it in your regular inbox. Then you can review the suspicious emails in Spam Blocker and choose to keep them or delete them forever. You can even send 'Bounce Back' messages to the spammers telling them that your email address does not exist so they remove you from their lists! Spam Blocker automatically Removes Attached Viruses, and can block unwanted email by Country, Email Address, Domain, and Keywords using our pre-defined Blacklists (or create your own). You can setup Spam Blocker to check multiple email accounts. You can even Import your address book from Outlook, Outlook Express, Eudora, or any .txt file so you don't have to worry about email from people you trust getting marked as spam. It's so simple, you'll wonder how you ever lived without it !
