Check Point has recently released a very helpful MTA Debugging and Performance Troubleshooting Toolkit (sk120260).
The Toolkit Download is available for Security Gateways R77.30, R80.10 and above.
This Toolkit is intended to help identify and debug problems in the MTA components and e-mail flow through the MTA (such as e-mail latency, e-mails not reaching their destination, etc.).
