Absolutely. If using an RBL it is important to understand that you pass
out the control over who's mail can come through to a third party where
you have no influence about. Spamhaus is certainly one of the good ones,
but they decide whom to list and you adopt that policy.
+1 for using a milter rather than using the dnsbl feature.
