Sendmail Inc.'s Sentrion appliance: All-in-one e-mail security

Earlier this month, Sendmail Inc. of Emeryville, Calif., gave government customers what company officials say government customers wanted'an appliance version of its e-mail security software. The new Sentrion appliance is built around the company's Message Transfer Agent technology, which is currently deployed at the Air Force, the Office of the President, the Senate and the House of Representatives.

'Some government customers were demanding an appliance,' Sendmail senior vice president of marketing John Stormer told GCN. The all-in-one platform, which includes Cloudmark anti-spam and McAfee antivirus software, is designed to help ease agencies' procurements. 'They can get the whole e-mail security suite with one purchase order,' Stormer said.

Sentrion runs on a hardened version of Linux that's purpose-built by Sendmail. John Ore, director of product marketing, said the company stripped out superfluous functionality and tuned the OS for gateway use. The hardware itself is a Dell PowerEdge server in either 1U or 2U configurations. The Sentrion offers two levels of policy control. The first is connection control, in which you can manage SMTP connections prior to scanning in order to throttle senders, check for valid e-mail addresses, etc. The second is content control, which is where the Cloudmark and McAfee scanning comes into play. Stormer said raw throughout was about 1.5 million messages per hour. Turn on antivirus scanning, for instance, and the system handles more like 300,000 message per hour
