configure with --enable-rlookups; then add to ACLs rules of the form

access to ...
	by ... ...
	by domain="my.domain" write
	by domain="other.domain" read
	by domain="spammers" none
	by ... ...

Is this what you mean?  Beware that rlookup may be expensive,
depending on the performances of the DNS in your system.
