This was something I worked with some time ago, when I was a sendmail
guru.  It's called userdb, is poorly documented in the bat book, and
rarely documented elsewhere from the sendmail distribution proper.
However, it *is* designed for precisely this problem.

If anybody's still interested, I could dig up my old notes on how to do
it.  I remember you *do* need to have Berkeley's libdb active, though.

qmail does this *much* better, BTW, which is part of the reason I moved
to it.
