The issue has been resolved and mail configured sensors should be recovered now. The fix was automatically pushed from our backend to On-Premise and Hosted sensors to resolve the signature bundle which caused issues. A more detailed post mortem will follow.

If you have ongoing issues, please reach out to the support team.


The issue has been identified with a signature bundle that was pushed from our backend. We are deploying a fix and are actively monitoring it.


We are currently investigating issues with MTA inline mail configured sensors. You may see "Analysis queue utilization at 100.00%" in email monitoring logs. We are working on it with our internal teams and will provide an update as soon as possible.
