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 firstname.lastname@example.org
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 (email@example.com) and then A
establishes a new SMTP connection to C.
