Cause

A malformed rule file caused the Brightmail Engine to repeatedly exit and restart. While the Brightmail Engine was in this state, messages could not be scanned and so accumulated in the Inbound and Outbound queues.

Resolution

This issue is an extremely rare occurrence in which a malformed rule file that could not be loaded by the Brightmail Engine.

The issue was resolved via a subsequent anti-spam rule update which replaced the malformed rule file. For typical configurations, no messages were lost or went unscanned.
