Hmmm...not sure what you're asking here (probably due to my lack of
sendmail knowledge). I am running a local caching name server, and my
linux box is working as a mail relay. Sendmail queues everything and
doesn't resolve ANY "To" addresses until send time (i.e. "sendmail -q" is
run, presumably from a cron job). Running sendmail -q starts the
resolution of the "to" and "cc" addresses (forcing the link up if those
names aren't in the cache) - names are resolved, mail is sent, the link
goes idle and times out, and then is brought down. No problems. I'm not
using a smart host relay - it's all just straight forward queuing and
canonification delay. Works just fine for me. Do you have problems with
this setup? What does your host.mc file look like (assuming you're using
m4)?
Similarly Curious (and somewhat dangerous with my borderline sendmail
knowledge),

P.S. - Apologies to the list - this discussion is probably more suited for
the sendmail list versus this one
