I have on IIS7 and on the same subnet is my Kerio (mail server) server. Any idea on what i should put for Settings? I have tried every combination (except the correct one) that i can think of. I keep getting this (or other) error:

Error: Error sending email in SendMailMessage: Failure sending mail. Unable to connect to the remote server A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond XXX.XXX.XXX.XXX:XX (IP and port removed for security reasons.

Is there a local firewall on the server that might be blocking port 25 (for example, depending on what port you're using)?

There is no local firewall on the server that is on.
