Pegasus Mail is a free, standards-based electronic mail client suitable for use by single or multiple users on single computers or on local area networks.
A proven product, it has served millions of users since it was released in 1990.
Pegasus is extremely feature-rich and powerful, yet remains small and fast. Since Pegasus Mail does not make changes to the Windows registry when installed, it is suitable as a portable application for USB drives.
Supports the POP3, IMAP, and SMTP protocols as well as Novells MHS. The current version has added support for spam filtering.
Free for Win98/ME/NT/2000/XP/Vista.
