The two do very different things. MTA blacklists are direct rejection of incoming smtp connections by the MTA (in this case postfix). URIDNSBL is a SpamAssassin check of web sites in message bodies. Specifically it checks message body URIs against sbl.spamhaus.org, SURBL.org, etc. Best practices is probably to use both. Disabling either one will let a lot more spam through. BTW, please don't use cbl.abuseat.org; it is already included in zen.spamhaus.org, so using it creates double the DNS traffic unnecessarily and with little or no gain. Jeff C.
