Pegasus Mail
What Pegasus Mail is
Pegasus Mail is a free, standards-based email client for Windows computers and local area networks. It supports one user or multiple users on the same computer or network, and it can work offline. The official downloads page lists version 4.91 and requires Windows 7 or later. Supported mail protocols include SMTP, POP3, IMAP4, LDAP and PH, with SSL available across those protocols. Mail handling includes automated rule-based filtering and the Bayesian SpamHalter filter. An encryption interface supports plugins such as PGP. The maker says Pegasus Mail contains no spyware, malware, advertising trackers or components that collect personal information about users or usage patterns. Gmail setup uses an app password, with two-factor authentication recommended for the Google account. Support comes through a community site and volunteer mailing lists. No macOS, Linux, mobile or web edition is listed.
