Google announced that it has added some security-related features for email in Google Apps for Business, Government, and Education. These include mail routing, delivery controls, SMTP relay, attachment compliance, and TLS encryption of message content.

Mail routing, delivery controls, and the SMTP relay service, Google says, will let you control the flow of information to and from your company with policy-based routing. This, it says, will ensure that messages are filtered, even when sent from third-party or other non-Gmail sources.

Attachment compliance, Google says, will let you protect your business by blocking or rerouting messages based on what is attached to emails. It provides controls for what content is sent and received.

TLS encryption of message content prevents eavesdropping and message spoofing through secure encryption and delivery, according to the company.

“In addition to these increased security measures, as we recently announced, we’ve now turned off ads in Google Apps services,” says Google Enterprise president Amit Singh. “This means administrators no longer have the option or ability to turn on ads in these services. We’ve also permanently removed all ads scanning in Gmail for Google Apps, which means Google does not collect or use data in Google Apps services for advertising purposes.”

Those showing AdSense ads on Google Sites will be able to display the existing ads on their sites, but won’t be able to edit or add new AdSense ads to new or existing sites.
