Guide Review - GNUMail.app 1.2.0 - Free Email Program
GNUMail.app is a slick and smart email client with lots of powerful features. Most notably, it comes with extensive filtering and can pipe mail through external filters (like SpamAssassin), too. GNUMail.app handles multiple POP, IMAP or local mailboxes gracefully and you can enhance it with secure messaging using GnuPG (no S/MIME, though).
It's a pity that GNUMail.app lacks support for HTML, and the plain text editor is not too powerful either, but for the most part it still does the right thing.
Solid support for international languages is another of GNUMail.app's pluses, and if you converse in threads you will appreciate GNUMail.app's display of arcs representing the connections between messages.
