Google Apps Administrators now have access to stronger and better management features. Admins can now access and configure improved email compliance footers, approved/blocked sender lists and file attachment policies for Gmail, directly from the control panel. Previously, Google Apps customers used Google Message Security, powered by Postini, to provide these capabilities.  While Message Security for Google Apps -- the integrated version of Postini -- is no longer available for sale or activation, existing customers will continue to be supported. Over the next few months, customers will be transitioned to the new email management features in the Google Apps control panel. These settings can also be configured at the organizational unit level for fine grained policies.

Also available to Admins are new support tools, including the Log Analyzer and Message Header Analyzer.
To diagnose issues pertaining to our migration tools, sync tools and email delivery, Admins can use the Log Analyzer which evaluates logs from a variety of our migration / sync tools and gives guidance on resolving most issues visible in the logs. You can click one of the links below to visit the log analyzer for that tool:

Google Apps Sync for Microsoft Outlook
Google Apps Migration for Microsoft Outlook
Google Apps Migration for Microsoft Exchange
Google Apps Connector for BlackBerry Enterprise Server
Google Apps Directory Sync

There you are Admins, all your solutions under one roof. Time to sit back, take a break and allow Google to help!
