This tool helps you keep your electronic mailbox free of spam. It looks at the relevant parts of e-mail before it leaves the mail server and lets the legitimate messages pass through undisturbed while leaving suspect messages on the server. They are, in effect, invisible to the e-mail client. These messages can be re-examined later or just deleted after a given period of time. This works as a POP3 e-mail proxy with support for POP and IMAP servers and as a result, it s compatible with all e-mail readers.
