I need some pointers from a few of the sendmail gurus.

I am trying to configure a sendmail hub on my internet perimeter that
accepts mail for domains x, y and z.com. Incoming mail addressed to
users@y and z.com will be forwarded to hub1.fake and mail addressed to
users@x.com will be forwarded to hub2.fake. The internal network is
hidden from the internet so only HUB.z.com knows about hub1.fake and
hub2.fake.  

Mail for all 3 domains is arriving at HUB.z.com now so my dns mx records
for x, y and z.com appear to be setup correctly, but I am not quite sure
where to configure the splitting of the domains so that user@z(or y).com
goes to hub1.fake and user@x.com goes to hub2.fake. 
Right now HUB.z.com is forwarding all 3 domains, x, y and z.com to
hub1.fake. Would this be done with internal fake.com mx records? Or some
sendmail.cf ruleset options at HUB.z.com?

Both hub1 and hub2 masquerade as their repsective domains and need to
send outgoing mail to HUB.z.com for either internet delivery and or
routing between x.com and y or z.com. I assume no special configuration
is needed at the internal hubs other than to forward to HUB.z.com?
D{REMOTE}HUB.z.com ?

I am using sendmail 8.8.6 and Freebsd 2.2.2-R. I have compiled bind 8.1
but have not installed yet, is it necessary?

TIA...
