email client probs

I am very new to this so I apologize ahead of time for any confusion. My office is connected to the internet through our landlord. He has the service and offers it to his tenants using a router. I am using Outlook to organize my email and it will not send messages. I usually get the message "Relaying denied. IP address possibly forged." All of my settings are correct... what does this mean?
Thanks!
