yMail2 is a rewrite of the original yMail, using a completely new programming language.
yMail can be used as a spam cleaner for your existing email setup, and also as a standalone email client.
yMail is a POP3 email client with an intelligent filter which trains itself to recognize spam from the contents of your inbox. It can also be used purely as a pre-filter for your existing mail program, sitting in the system tray and cleaning spam automatically before you download it. yMail also includes email notification, displaying an unobtrusive icon when you have mail waiting.
