Eudora used to be the king of the free third party Macintosh email applications. It supports SMTP, POP and IMAP servers, stationery, provides multiple mailboxes, filtering, offline reading and replying, and - most importantly - is very, very reliable.
Version 6.2.4 is officially the last commercial version of the old Eudora application that is so well-known and loved. On October 11, 2006, Qualcomm announced:
"Future versions of Eudora will be based upon the same technology platform as the open source Mozilla Thunderbird email program. Future versions of Eudora will be free and open source, while retaining Eudora's uniquely rich feature set and productivity enhancements. Qualcomm and Mozilla will each participate in, and continue to foster development communities based around the open source Mozilla project, with a view to enhancing the capabilities and ease of use of both Eudora and Thunderbird.
"Qualcomm also today announced that it has released the final commercial versions of the current Eudora products for Windows and Mac operating systems. The open source version of Eudora is targeted to release during the first half of calendar year 2007. Once the open source version of Eudora is released, Qualcomm will cease to sell Eudora commercially. In the interim, Qualcomm will continue commercial sales, at a reduced price of $19.95 and with a six-month period of technical support. Existing technical support commitments will be honored in their entirety.
"'I'm excited for Eudora to be returning to the open source community,' said Steve Dorner, vice president of technology for Qualcomm's Eudora Group. 'Using the Mozilla Thunderbird technology platform as a basis for future versions of Eudora will provide some key infrastructure that the existing versions lacked, such as a cross-platform code base and a world-class display engine. Making it open source will bring more developers to bear on Eudora than ever before.'"
Andrew Starr's Unofficial Eudora Site links to more information about the new product (codenamed "Penelope"), including a discussion forum. The official "Penelope" development page has more information, and as of September 2007, you can try out the latest (beta) release below!
No longer available in "Paid" mode (which was equivalent to the old Eudora Pro, but which required an annual subscription fee), Eudora 6 can now be run in one of two "modes" - "Sponsored" mode, which gives you all the features of the former "Paid" mode (except for spam filtering) for free, displaying advertisements as you use the program; and "Light" mode, which eliminates several of the coolest features of the program (but doesn't display advertising, either), giving users an equivalent to the old "Eudora Light" application, albeit a much more up-to-date version. Sponsored mode adds many features, including a built-in spelling checker and more sophisticated message filtering.
Eudora versions 5.1 and later are for Power Macs only; users of 680x0 Macs will have to keep using the older Eudora Light software, which is still available.
At any rate, version 6.2.4 added/changed the following:
As of version 6.2, new versions of Eudora are available for Mac OS X only; as of versions 6.0 / 6.1, support for PowerMacs was limited to those machines running OS 9 or higher; older versions may be purchased through http://www.soft-net.co.uk.

In order for Macintosh Eudora to work well under OS X 10.5.x 'Leopard', you need to turn off the use of specific sounds in Eudora. These are the sounds Eudora plays when you get new mail or Eudora needs your attention, or are played by Filters. The sounds that are problematic are the ones that contain 'Eudora' in their name as they were created using a sound synthesizer that Leopard does not support. To disable or change the sounds used in Eudora, do the following:
Turn off or change the 'New Mail' and "Attention" sounds:
Turn off sounds triggered by filters:
"I actually love this software. It is easy to use, there is so much freedom to set user preferences. If you have as many Internet addresses as I do--five which I check daily--with the click of the mouse, you can retrieve your mail from any server without the hassles of constantly changing or forwarding your mail to a designated mailbox. It is a must have."

"I respectfully disagree. I have at least two other mail programs, one of which comes "free" with OS X, that check multiple accounts easily for me. To me at least 50% of communication is in the presentation. If you do not communicate your point clearly and with impact you are missing the boat. Unfortunately, Eudora's output, particularly of graphically designed html-based email, is simply ugly and unacceptable. The makers have much work to do, particularly if they hope to get money for this program or be allowed to pester you with advertisements. And it is also unacceptable, in the OS X version, to force you to load Classic when you click on an ad. This app is clearly hampered by an old-fashioned mindset."

Finally, take a look at ALEMIA if you think you know that name of an application, but aren't quite sure.
Graham Orndorff has written a superb collection of articles on setting up email servers and secure email clients on Mac OS X.
Adam Engst has put together a comprehensive overview of email attachment formats that is invaluable for anyone who wants or needs to understand the complexities behind them.
These are applications that are newer and of potential interest, but which I haven't yet selected for permanent inclusion. Have a look, and let me know if you think they deserve to be part of the permanent collection!
