From the developer:
PostArmor is an application that helps to keep your electronic mailbox free of unsolicited e-mail, better known as spam: it looks at the relevant parts of your email before it leaves the mail server, and lets the legitimate messages pass through undisturbed, while leaving suspect messages on the server to be reexamined later or just deleted after a while.
