Q: Is there a way in which I can see if Apple firewall is blocking traffic to/from a certain IP address?

Connection to my email domain seems to be blocked by some instance between my home network (using Apple AirPort) and my email server at an external service provider. I can log into that fine through my mobile provider, but not from my home network. This leads me to believe it may have something to do with Apple's firewall blocking te traffic. Where can I see if this is the case? Any other possibilites or things to check?

iMac, Mac OS X (10.7.2)
