Kind of dated reply, oh well :).
This seems strange because as far as I know, all 10.*.*.* addresses are
supposed to be internal only. If true, then if that machine (10.0.0.30) isn't
on your network it's sadly misconfigured. I don't see how a machine could
send data out to the internet with such an IP address.

Obviously, you'll want a different IP address.

As I understand it, postfix is relatively secure, if not better secured than
Sendmail. But with sendmail you could point to it and say "OK" this system
is not an open relay, by inspecting the various rulesets. I am not as familiar
with Postfix, so I can't just point to it and say "here is where the relay
protection rules live".
