theefer writes "Qualcomm announced that 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. [...] 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."
