SafestMail manages your e-mail by creating lists of approved and denied senders/domains/subject beside special rules. Unknown senders will receive an e-mail asking why they want to send a message - a popup will request your permission. Your address book and previously (and new) sent e-mails are used to automatically create a white list. SafestMail also helps block Trojans and viruses in outgoing e-mails, and works with all e-mail programs.
