If the destination is not on the machine itself, the destination
should be listed in relay_domains.
transport_maps is not a substitute for relay_domains (think, for
example, of sites that have special configuration for hotmail etc.;
such sites do not automaticaly "relay" everyone elses mail to
hotmail).
There are some useful hints and tips in the firewall/gateway
example in STANDARD_CONFIGURATION_README.html
