I'm not sure if DNSRBLs are the same as URIDNSBLs, or if this was the intent of the original poster
It was a mistake on Chris's part, and he replied as such.
As for the difference, the two are definitely not the same..
DNSRBLs work by listing the IP addresses of various mailservers that fit certain spam criteria, and are used for Received header parsing..
URIDNSBLs are intended to list the targets of URI's (aka web links), not mail relays.
Some services are actually applicable to both situations, but not many. The SURBL spamcop URI list is clearly not very useful as a DNSRBL. The original spamcop spam-relay list (not the one hosted by surbl) is not very useful as a URIDNSBL.
Even though both are generated by the same reports to spamcop,and both are queried using similar mechanisms, they each list data extracted from different parts of the spam, and are most effective when checked against the same parts they were extracted from.
