Well that's odd. I guess things must be spotty, as I've definitely seen
this in the past. I had a customer with exactly the same problems. I
tcptracerouted on port 25 from the US to the host in question, and
things definitely stopped at TCL international border in NZ. It must not
have been my imagination, as they're still paying us for the solution.

I've doubled checked, and that seems to be the case.

Network 203.96.154.0/24 is not filtered, but Network 203.79.97.0/24 is.
