GuardMail 5.0

Motino 1.1
Motino is at the same time very easy to use and very efficient at removing spam from your Outlook Inbox. There isn't much more to say, it just works -- unfortunately not with IMAP, though.

PowerMail 4.2
PowerMail is a great Mac email client with powerful filters, unparalleled search functionality and great overall usability.

ActiveRefresh 1.37

Jetable.org Disposable Email
Jetable.org provides easy to use disposable email addresses that auto-expire after a certain time. Useful when you need an address just once, it's not an all-around disposable email solution.

Spam Xploder
With Spam Xploder, you not only get a solid email account but also great server-side Bayesian spam filtering that spares you downloading the junk. Support for more email clients would be nice, though.
