Eudora 1.0

Eudora... Now based on Mozilla Thunderbird. The Penelope project's intention is to join the Eudora user experience with the Mozilla platform.

We intend to produce a version of Eudora that is open source and based on Mozilla and Thunderbird. It's *not* our intention to compete with Thunderbird; rather, we want to complement it.
We are committed to both preserving the Eudora user experience and to maintaining maximum compatibility, for both developers and users, with Thunderbird. It is our goal to build a single development community around Thunderbird and Eudora, so both mailers advance faster than they previously have.
Eudora has been a QUALCOMM product for many years. QUALCOMM continues to have a keen interest in the users of Eudora, and is being kind enough to donate the time of staff members to the Penelope project.
