I tried Mail Washer a while back. The free version only allows one account, but I get mail through 3 different servers. After trying it, I decided I liked Pop Tray better. Pop Tray isn't as well known, however, but did get 6 ducks at Nonags.

(free) Mailwasher allows checking multiple e-mail accounts -- not sure if that's a new feature.
