End of Eudora support
We stopped supporting Eudora since we've switched to using Zimbra because Eudora is not compatible with the new Zimbra mail server.
The last commercial versions of (QUALCOMM) Eudora, version 7.1 for Windows and version 6.2.4 for Mac in 2006.
The Open Source version undertaken by Mozilla (code name Penelope)is obsolete (no new developments), and has now been folded into Mozilla Thunderbird.
You can download the latest version of Thunderbird at: http://www.mozilla.org/thunderbird/
