We are using the Exchange Server (via SNMP) template for monitoring one of our Exchange servers. The problem is that the SMTP Monitor (a simple port 25 monitor as far as I can tell) isn't able to connect. I get this error:
No connection could be made because the target machine actively refused it 192.168.10.8:25
However, I can telnet to port 25 form the Orion server with no problem.
