If Trend Micro gets back to you with an explanation, please post it here to help others with the same issue.
In corresponding with Trend Micro over the issue I found that disabling the Trend Micro Security Agent Listener service is not a good idea. To quote them:
Quote:Trend Micro Agent Listenter is the service who checks communication between the agent and the server. If you turn off the agent listener service, agents will not be able to get updates from the server.
They recommended re-enabling the service and try turning off URL Filtering or Web Reputation on the Security Server to see if that helped.
What I found is disabling both BOTH the 'Web Reputation - In Office' AND 'URL Filtering' features is required to avoid getting the SMTP connection problems in Kerio.
As the server is not used for browsing, this is satisfactory solution. Trend Micro did offer some further troubleshooting advice, but I haven't had the need to take it any further:
Quote:Another thing we can try is to IP whitelist the IP address of the machine then whitelist the executable file for Kerio. Please refer to the link below:

I hope this helps anyone else who may come across this problem.
