This is not an answer, but I don't see an RBL hit as a '..error in processing'
at either end. Result of an error in past behaviour, maybe, but....

FWIW, we are doing that with a code 550, "Administrative prohibition"

- or less-polite words to that effect)

And for a while, after an all-nighter on MLM integration coding left an
octothorpe out of a key place in ~/configure, we were doing it to damn-near
everyone...

:-(

Sorry 'bout that...
