Best email program?

[Simon]

I've used the original version of Eudora since 1996 but I plan to check out the Open Source version (which uses Thunderbird code). I'm running Mac OSX Snow Leopard right now but when I upgrade to OSX Lion it seems I won't be able to use the classic version of Eudora any longer.

From the page at http://www.eudora.com/faq/OSX_Lion.html

Important Announcement about Mac Eudora and Apple OS X 10.7 "Lion"

In Mac OS X 10.7 "Lion", Apple has removed support for "Rosetta". It is Rosetta that allows Mac Eudora to continue to run under Mac OS X (up to and including OS X 10.6 "Snow Leopard"). Once you upgrade to OS X 10.7, Mac Eudora will no longer function.

Let's repeat that:

Mac Eudora WILL NOT run under Mac OS X 10.7 and later.

Before upgrading to OS X "Lion", be sure to transfer all of your mail to another email client as you will no longer be able to access your mail using Mac Eudora.

So long and thanks for all the fish...
