redo the test with IP addresses instead of domain names. test both the
internal and external IP of the gateway (127.0.0.1 doesn't count).

redo the test above using the internal IP of the gateway. make sure the
request really reaches the gateway machine (watch for intermediary
routers/FWs). make sure the request really goes to postfix (make sure
the gateway isn't configured as a FW that rejects your connection).
also make sure that postfix is listening on these IP addresses. don't
play with inet_interfaces unless you know what you're doing.
finally, read the DEBUG_README document.
