Thanks for the responses.

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.

Regards and many thanks,
Benedict
