If you're only a smart host for your customer who is actually the open
relay, then at worst you should find yourself on their "outputs" list, but
not on the "inputs" list. I only use the inputs list, which is what they
recommend for exactly that reason...if others use the outputs list they do
so at their own peril.
Yeah, it might be a bit of a pain for you, but it has served its purpose -
it's alerted you to an open relay within your netblock which more than
likely has already passed some spam. (Otherwise nobody would have bothered
to submit it to orbz in the first place) Actually I think they should
notify the netblock owners by default rather than being "opt in", as it
would get a lot more open relays fixed, but they say that would constitute
spam ;)

Heh. I don't think I've come across that one. Yet...
