It's possible to add a header in the data acl and reject in a router where
domains = ! +liberal_domains.

I do basically the same thing for spam scanning, storing the maximum of
all recipients' spam score thresholds in acl_m0 and rejecting in the
data acl if possilbe (i.e. the score is above acl_m0.) If it's below
acl_m0, I reject in a router for recipients whose max spam score
threshold is less than the message's spam score.
