Yes.  It's effectively not much different from a DNSBL check, so all 
the usual MIMEDefang caveats for enabling those apply.

So far it's been extremely effective, triggering on ~60% of caught 
spam with zero false positives.

My understanding is that the SURBL list utilizes data from SpamCop 
reports, with some checks in place to prevent common false positives. 
It remains to be seen whether it will remain as effective once the 
spammers decide to try poisoning the SpamCop system with false 
reports.
