Control Mail PRO is a shareware program that allows you to see the subject lines of e-mails and erase them without having to download them. It works the same way as any other POP3 servers. It also contains filters that allow you to remove all messages sent from pre-determined addresses, that contain certain keywords, or that will be returned to pre-determined addresses.
It contains a browser, a translator, and other tools to navigate the internet.
In this version, there isn't a limit on the number of filters that can be used, messages can be marked and erased automatically, and much more. Messages are erased on the server without having to download them to your computer.
