Can not connect to Exchange 2010

I’ve written a utility application that simply pings all the “significant” hosts on my network and then sends me a text message if they don’t reply after three attempts at ping.
The issue is, I can’t send the email from my app via Exchange 2010.
I have three receive connectors, the two that are installed: Default and Client we’ve also added one for Relay.
When I try to telnet to my exchange server on port 25 I get “Connection Failed”
From the software I get “Server Actively Refused Connection”  which to me implies that my exchange server is not taking call on port 25 from my IP address.
I’ve added my entire subnet 10.10.0.0/16 to the relay receive connector.  Other systems, such as our color copier which scans to users email boxes needed to be added to this relay connector and they are working correctly.
So any ideas why my exchange 2010 server is not accepting my connection from my laptop?

Do you have a virus scanner installed that blocks sending from port 25?  This is the default behavior for McAfee for example.

The virus scanner was indeed blocking 25. Thanks!
