Fetchmail

Fetchmail is a full-featured, robust, well-documented remote-mail retrieval and forwarding utility intended to be used over on-demand or permanent dynamic-address TCP/IP links (such as SLIP or PPP connections). It supports every remote-mail protocol now in use on the Internet: POP3, IMAP4r1, ETRN ...

This setup allows all your system MTA's filtering, forwarding, and aliasing facilities to work just as they would on normal mail. [Less]
