i've wondered what heuristic get applied in these cases
(in general). unlike the rbl these types of checks are
not fail safe.

I think checks of that sort are ill-advised. How can an MTA tell if
cd.chalmers.se exists or not? Just because it tried a DNS lookup and
it failed, that doesn't prove anything; transient errors are routine on
the Internet.
