Ok. Lets say A in New York is sending Mail to B me@mydomain.de here in Binau
(Germany) and on my mailserver for mydomain.de I have configured an alias
(forwarding) from me@mydomain.de to annother address in Tokio
he@anotherdomain.jp (C)

The question is if the mail travells from New York to Binau and then from
Binau to Tokio, causing twice the traffic on my internet-connection or is it
possible that the mail goes directly from New York to Tokio causing nearly
no traffic on my line.

But New York is still sending to me@mydomain.de

This must happen during the SMTP connection from A to B where A gets the
info from B that the mail should go to C (he@anotherdomain.jp) and then A
establishes a new SMTP connection to C.
