Hi Ceri, Providing DNS resolution for a private IP address is treating the symptom, not the cause. If your host uses such a private IP address then it cannot represent itself publically on the Internet. In such a case, your organisation will provide a mail gateway for your domain and internally sourced mail should rewrite addresses as if they originated from this machine. You should also arrange for these internal hosts to collect their mail from the mail gateway and not expect it to be routed. The action of hub.freebsd.org is normal in attempting to check that the supplied IP address matches that of a host lookup - for a system that employs relaying controls.
