Google Message Security, powered by Postini

Google Message Security
Protect your email from spam and viruses and set email policies to stay compliant

Google Message Security, powered by Postini is the virus, spam and email security service offered by Google. It can be purchased as a stand alone service but is included in the Google Apps for Business core package. 

Message Security works with Google Apps mail to provide:

• Content and attachment filters, which you can create to enforce your company's policies for inbound or outbound messages
• Outbound messages footers, that you can customize for different groups of users in your Google Apps account
• Support for TLS encryption to set up secure connections for inbound and outbound mail connections
• Another layer of spam and virus filtering, in addition to the filtering that Google Apps already provides
• The Message Center, which lets users manage their quarantined messages and set up their own approved and blocked senders lists

Here's a brief video to explain what Google Message Security, powered by Postini does.
