For those who have been using email since the dawn of time, Pegasus Mail is a well known name. For those of you who started out reading your first email in Outlook, chances are you have no clue what Pegasus Mail is.
Before I dive into what the new release entails, let’s just give those of you who are not familiar with Pegasus Mail a quick introduction. The first release of Pegasus Mail was launched back in the ’90s and was initially developed for Novell NetWare (a cut-down version of Pegasus Mail called FirstMail came bundled NetWare). Later on, support for MS DOS and Macintosh, and even later, Windows was added (Wikipedia).
While Pegasus Mail might not be a very popular email client today, it still lives on with its faithful users. Pegasus Mail does offer some interesting features, such as a built-in Baysian spam filter, its own HTML rendering engine, and support for the MTA — Mercury Mail Transport System (also written by David Harris). As most other email clients, it supports POP3, IMAP and SMTP.

Ok, enough about the background of Pegasus Mail. What’s new in this release? Windows 7 support and dropped support for Windows 9x. In most cases dropping support for Windows 9x is not a big deal (since it has been EOL’ed for quite some time). In this case however, I can imagine that it is a big deal, as it’s not hard to imagine that many of Pegasus’ users are very conservative and might very well still be using Windows 98SE.
