You are trying to monitor the quarantine SMTP service and have problem with port 41025 not responding to the monitoring software.
The Quarantine port 41025 is not a true mail server port. It is a specific use process for the Messaging Gateway Scanners. There is no expectation that it will respond appropriately to SMTP monitoring.
Release : 10.7
Do not configure your SMTP service monitoring to check the quarantine port 41025.
