We identified the root cause of the unexpected engine behavior that led to the increased false positive rate. The affected engine has been disabled, and all impacted messages have now been released. Any remaining messages are currently being processed automatically in the background and will be handled shortly.

A fix has been implemented and we are monitoring the results.

We are experiencing a high rate of FP due to unexpected engine behaviour. The engine was truned off and we are working to rescan all recent traffic and release the false detected emails.
