What does it mean if your email was undeliverable because a target machine "actively refused" it?

When you are getting this error:
"No connection could be made because the target machine actively refused it", it's usually not an authentication problem, simply because the server rejected the connection before you were even able to present the credentials.
Here's what I would do:
1)Trap the exception. Then loop through all the inner exceptions to verify this is the real error.
2)If it's the real error, this is usually because
a)There is a firewall in the way,
b)the remote smtp server is blocking your incoming requests, or
c)Something is blocking your outgoing port 25 requests.
