VeriSign on Monday announced a new e-mail security service designed to stop viruses and spam.

The service uses custom blacklists, fingerprinting and heuristic tools, which calculate the probability that a particular e-mail message is spam by examining a pattern of characteristics in the message. VeriSign's heuristic tools use more than 10,000 rules to determine whether a message is spam, the company said.

For blocking malicious mail, the service deploys three antivirus engines. For policy enforcement, customers can use domain-level filtering to scan inbound and outbound e-mail. And a disaster recovery feature allows for automatic switchover to VeriSign's network to provide SMTP connections that queue e-mail, if a company's e-mail server is not available.
