Pegasus Mail is an e-mail client that runs on computers using Microsoft Windows: by client, we mean that it interacts directly with the user, allowing mail to be sent, read, filed, printed and otherwise manipulated through a graphical interface. Probably one of the most feature-rich mail clients available, most users say that they find the program easy to use despite its richness. Small and fast, Pegasus Mail can be left running permanently on the workstation and includes powerful tools to notify the user when new mail arrives.

Pegasus Mail can run on single Windows computers, or local area networks - it has special support for Novell NetWare LANs that allow it to operate intuitively and with almost no maintenance. The program also supports multiple users on a single computer. Versions are available for both 32-bit Windows (Windows 98, NT4, 2000, XP and Vista) and 16-bit Windows (any version of Windows 3.1 or later). Pegasus Mail can act as a complete internal mail system on its own without needing further servers or components: it can send and receive Internet mail on its own using standard protocols (SMTP, IMAP and POP3). By adding our Mercury Mail Transport System as a mail server, you can provide fully-integrated centralized Internet e-mail services and mailing list management for your Pegasus Mail users.
