Email Continuity Customers – Mail Delays [RESOLVED]

MxToolBox Email Continuity customers experienced mail delays the morning of August 6, 2010 from 7AM-11AM Central Daylight Time. Spam and Virus, and Hosted Email customers were not effected.

Forged NDR messages were caught in the Continuity Engine and replicated quickly into a large volume of mail that caused legitimate messages to be delayed. We put new safeguards in place to drop these messages, cleared the queues, and mail flow resumed.

In addition to these new safeguards we are examining how we can better configure our mail flow for these customers to be able to quickly adapt their configuration and quickly route mail around a delayed gateway in the future.
