PopScan is a simple and easy to use e-mail checker with built in spam filtering options, dial-up support and more. It notifies you of new mail via system tray icon or optional sound. Furthermore, the program allows you to preview the subject lines of new mail (but no the content) and to delete selected messages or to block the sender from further mailings. The built-in spam filter allows you to delete messages based on subject, sender and message size and uses a rule-based filtering system.
