SafestMail Personal Edition 3.0
This program manages your e-mail by creating lists of approved and denied senders, domains and subjects.
Unknown senders will receive an e-mail asking why they want to send a message and a popup will request your permission. Your address book and previously sent e-mails are used to automatically create a whitelist. SafestMail also helps block Trojans and viruses in outgoing e-mails, and works with all e-mail client programs.
