Eventually many email clients were written for personal computers,
but few became as successful as Eudora. Available both for the IBM
PC and the Apple Macintosh, in its heyday Eudora had tens of
millions of happy users. Eudora was elegant, fast, feature-rich,
and could cope with mail repositories containing hundreds of
thousands of messages. In my opinion it was the finest email

I still use it today, but, alas, the last version of Eudora was
released in 2006. It may not be long for this world. With thanks

its historical interest, and with the faint hope that it might be
resuscitated. I will muse more about that later.
The Windows version of Eudora is written in C++. The source tree
consists of 8,651 files in 565 folders, taking up 458 MB. There

The Macintosh version of Eudora is an entirely different code base
and is written in C. The source tree consists of 1,433 files in 47
folders, taking up 69.9 MB.
