YAM (short for Yet Another Mailer) is a MIME-compliant e-mail client written for AmigaOS based computers. It supports multi-POP3, APOP, SMTP, TLSv1/SSLv3, multiple users, PGP, unlimited hierarchical folders, filters, a configurable GUI (based on MUI) and an ARexx interface and many other features which are common for Mail User Agents (MUA) today.
The first version of YAM, developed by Marcel Beck, was released to the Amiga public in 1995. While it was usable, it was relatively basic in terms of functionality. The 2.x release featured a major redesign of the user interface and added a lot of new features. It was (and still is) the most commonly used email client on Amiga computers, thanks in part to the fact that it was always a freeware application. (Full article...)
