I solved it by adjusting the relayers list (i'm a domain admin) in others words i granted my pc the rights to relay. I did this by starting the Exchange System Manager and then going to Servers-><name of exchange server>->protocols->SMTP Then right click on "Default SMTP Virtual Server" and properties, go to the Access pane and near the bottom you have a button "Relay" in a section called "Relay restrictions". That's where i temporarily added my ip address. After sending the greetings mail, i removed my ip address again from that granted list.
