ChainMail's Mithril Secure Server enables ISPs and organizations to offer their users the ability to send e-mail in a secure, encrypted format. Chainmail has dubbed Mithril "The Antivore" and released it for free distribution in direct response to the Federal Bureau of Investigation's Carnivore e-mail surveillance system. The Mithril System provides server-side management of e-mail encryption and keys. It is implemented as a transparent shim between an e-mail user's existing mail client and their existing mail servers.
