Postbox 1.0.0 is now available for downloading.
I have been waiting (and waiting...) for MailForge (the "Eudora replacement") to be Ready For Prime Time, but it still has enough bugs that I haven't seen fit to press it into service yet.
I haven't played with Postbox much, but importing Apple Mail settings was easy and quick and my initial impression is that I like the user interface better than Mail and MailForge. The Eudora UI is sure looking dated after all these years. Heck, it was dated when it was still in active development!
Postbox's primary claim to fame is its organizational and search capabilities. And being a Mozilla-based program it can utilize plugins created by independent developers. (Postbox is apparently based on the Thunderbird engine.)
If you decide to purchase Postbox it will set you back $40; I guess that is the going price these days for third-party email software.
Here is a review of Postbox. Keep in mind that it was posted earlier this year while Postbox was very much a beta program...
