by ACMEtoolz.com   

A powerful manual/automatic mailbox cleaning utility with anti-spam capabilities for Windows. You can preview and delete unwanted e-mail messages directly from the mail server and retrieve the rest with your e-mail client (e.g. MS Outlook). Every message is shown with its sender's address, subject, size and the date it was received. POP3 Cleaner PRO can also run fully automated on the system tray and act as a powerful anti-spam filter. It can connect to the mail server in desired time intervals, check for the new mail (notify you on new mail arrival), apply the anti-spam rules and delete the unwanted messages directly from the mail server.
You do not need to change any settings on your computers. The installation and setup is very easy. Lifetime update for free.
