In particular try setting the score of URIBL_SBL to 0
since its style of SBL lookups is significantly slower than
SURBL lookups, and its FP (false positive rate) is higher.

(URIBL_SBL needs to resolve the NS records of the URI domain
and check them against SBL using another DNS resolution.  That
initial resolution of the wild domain can potentially be quite
slow since it uses various external name servers, potentially
including ones that belong to spammers.)
