Pegasus Mail 4.73
Pegasus Mail is a free, standards-based e-mail client that can be used by one or more users on individual computers or on local networks. A proven product, it has served millions of users since its release in 1990. It is extremely feature-rich and powerful, but remains small and fast.
Pegasus Mail can function as a complete internal messaging system without the need for additional servers or components: it can send and receive Internet mail by itself using standard protocols (SMTP, IMAP and POP3).
