OK. RFC1918.

I would normally suggest setting up split-brained DNS to handle
internal name resolution. But..

Lookup mailertable. I think the rule should be something like:
mydomain.com            smtp:[192.168.1.254]

Be sure to upgrade sendmail, because the recent overflow can
reach internal hosts. While I am at it, a plug for postfix: it is
a drop in replacement, and the transport map is documented very
well for this behavior.

Bind and sendmail. Ugh.
