I want to extract the mumble.aidemxwzlwt.bwbibibi.edu and run it
through AskDNS and if I get an NXDOMAIN, I want to score it.

Remember, there are historic mechanisms for an MX for parent domains

which, besides wildcard DNS?
OP, also remember that mumble.aidemxwzlwt.bwbibibi.edu may have no A/MX
record while not produce NXDOMAIN
I don't recall the current state of support for this, so don't rely on
it without testing it.
Is it possible to do this within a cf file?
I don't know. Someone else with more knowledge of SpamAssassin will
need to speak to this.
