Eudora goes open source

Eudora, the venerable mail client, will be open-sourced and merge somehow with Thunderbird. Specifics are at the Penelope wiki.

I've used Eudora since it first came out. I still do. The only other mail client that has really tempted me is Mailsmith because of its close integration with BBEdit. Unfortunately Mailsmith had no Kerberos support when I checked it out.
