Most features in Penelope can be accessed when used with Thunderbird, but there are a few that require Eudora in order to work correctly and it's not something that gets tested. The Eudora installer includes the corresponding version of Penelope along with it so there is no need to install Penelope if you are installing Eudora.

Whereas 'Eudora' is a branded version of Thunderbird with some extra features added by the Eudora developers, 'Penelope' is an extension (also called an 'add-on') that can be used with either Eudora or Thunderbird. It is our goal to build a single development community around Thunderbird and Eudora, so that both mailers advance faster than they previously have. We are committed to both preserving the Eudora user experience and to maintaining maximum compatibility, for both developers and users, with Thunderbird.

It's *not* our intention to compete with Thunderbird rather, we want to complement it. This (7.x) is the last sponsored mode version of Eudora. Use emoticons and personalized signature.
