You could get sendmail to not check the domains, add to .mc file:
FEATURE(accept_unresolvable_domains)

Another way might be to have your own cacheing DNS and use ipchains
to control access to it, i.e. add/remove rules in ip-down/ip-up.

Is it requiring an environment variable to be set which isn't
set when called from ip-up?
