Qualcomm has released Eudora 5.1, a free update to their popular email application. New features include support for secure, authenticated connections via SSL (Secure Sockets Layer) if your email server supports them; an option to display signatures inline in message composition windows; support for sending, receiving, and storing vCards; colorizing of MoodWatch trigger words and phrases (Paid or Sponsored mode only); and a new MoodWatch settings panel. Qualcomm rewrote Eudora’s Address Book for Eudora 5.0 (see "Eudora 5.0 Reads Your Mind" in TidBITS 547), and now we’re starting to see the benefits. Enhancements to Eudora 5.1’s Address Book include a conduit for synchronizing your Eudora Address Book with a Palm OS handheld, support for photos in address book entries and in nickname toolbar buttons, the capability to export the Address Book (or just selected entries) to a comma-delimited text file, and a new Address Book settings panel. In addition, Qualcomm fixed a slew of minor bugs. A 4.8 MB installer enables you to install a fresh Eudora Application Folder or update a Paid copy of Eudora 5.0.x (but not a beta version). For those running Mac OS X, a carbonized version of Eudora 5.1 is in beta testing now (it’s a 3.8 MB download).
