Pegasus Mail
Pegasus Mail is probably one of the most feature-rich mail clients available, and above all very safe. Developer David Harris released it in 1990 as one of the first e-mail programs in the market, first in a DOS version (you can still download it), and in many Windows versions. Versions are available for all 32-bit Windows (Windows 98, NT4, 2000, 2003, XP and Vista) and more recently also for Windows 7 and even 64-bits. Security, security, security: Pegasus Mail protects you from even the worst HTML-borne virus and trojans, and protects your privacy by intercepting web bugs. Pegasus Mail is immune to all the exploits that affect the “other” mailer - browse your mail with genuine confidence. Pegasus Mail’s built-in Spamhalter Bayesian filter learns from the spam you receive and automatically files it in your junk folder. Pegasus Mail detects phishing mail. It is a very complete program with many options that other programs don’t have. Once you’re used to the interface you going to love it. It is certainly my favorite. It also runs from USB stick.
