We solved this by having all the local clients route *all* mail to the
internal mailhost (ruleset 0 contains only one line). The internal
mailhost knows how to deliver mail to *.london.micrognosis.com (plus a
couple of other things) and punts everything else to the firewall.
Basically, nothing internally uses DNS to route mail - it's all wired
into the sendmail.cf files on the very few (2 or 3 ) machines that
route mail. Our internal mail network is simple enough for this to
work and be supportable. Your mileage may vary. Neil.
