Windows Mail (predecessor of: Outlook Express, Windows Live Mail) – a free and intuitive e-mail client from Microsoft.

The application lets you receive and send electronic messages in a very simple and fast way. Windows Mail has been equipped with an anti-spam and anti-phishing filter, which keep junk messages out and ensure protection against phishing attempts. Free e-mail program for handling e-mail accounts supports electronic mailboxes running on the POP3 and IMAP protocols.

Windows Live Mail uses a new style of Microsoft’s interfaces, called the ribbon, which was introduced with the launch of Microsoft Office 2007. If you are used to the minimalist look of Outlook Express, switching to Windows Live Mail may take some time and getting used to the new interface.

You can also subscribe to newsgroup lists, the application also has a built-in calendar and RSS feed reader (called as sources).

First release: December 1989


Pegasus Mail – a free, proprietary, standards-based electronic mail client suitable for use by single or multiple users on single computers or on local area networks.

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.

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.

The project developer is David Harris.
