Lydia 6.0.0 - Lydia Major

Lydia, the mail checker purportedly from Maeonia and first mentioned by Homer, gets an update that makes its spam filters more flexible and self-updating. Lydia 6.0.0 also renders HTML (securely, of course) and can be controlled from the keyboard.
Lydia checks your mailbox for new mail reliably, and removes some spam using blackhole and content filters, too. (Windows)
