Google just introduced message log search for Postini, its group of cloud security and archiving services.
"When messages pass through the Postini service, header and transaction data about these messages is stored in a log," explains Gopal Shah of Google Postini team Previously, admins only had access to this data through customer support. With the Message Log Search feature, email administrators can now easily run searches on these logs and drill down to the details about how specific messages were processed."
Administrators can look at things like whether messages were delivered, quarantined, archived, or encrypted.
"Say an admin was checking the delivery status of all inbound emails from Matthew Smith," says Shah. "Message Log Search returns results which include who received the message, date/time, disposition, and more."
The feature has been available in beta testing, and Shah says customers have found it useful for things like tracking errant emails, figuring out why certain people didn't get messages, proactively searching for "problem senders", etc.
Log search is now available through the Postini service administration console, and in Google Apps Preimier Edition.
