no, all my mail arrives at a machine in munich, germany, actually.
i use philadelphia as a backup mail receiver, and as a sending relay.
since i am on a dynamic IP connection here, i can't just relay based
on source IP, and i can't do without relay control, or else i'll die.
so i use TLS, which is like SSL in that it provides an encrypted
channel in addition to a client certificate. so my laptop has
a certificate and i told the philly machine to relay for anyone who
presents this certificate. now i am independent of the IP and can
travel around the world without ever changing my smarthost.

you don't know me. i'd die.
