Eudora Light 3.0.5
It takes more than a $0 price tag to make an e-mail client
as popular as Eudora Light. It takes strong message filtering, a solid Find
function, and built-in PGP encryption to safeguard the privacy of your messages.
The $39 full version, Eudora Pro Email 4.0, adds such features as the ability
to reply with automated responses and to view attachment files without the
originating app, multiple e-mail account access, and a customizable address
book. But for many users, Light is just right.
