Said another way, if you are using SpamAssassin 3.0 or newer with the default SURBL rules, then no changes are needed. All SurgeMail versions include: Mail, SSL, WebMail, unlimited Domains and our complete Anti-Spam system). Therefore please use multi, as is the default for SpamAssassin 3.0 and newer versions. SurgeMail provides a cost effective solution for systems of all sizes. As of March 1, 2009, public DNS service for the individual lists is disabled, and only is served. This is preferred since a single query to multi will get results for all of the individual lists.
Today I ran into an upgrade issue, after the recently released kernel update from 3.10.0-514.21.1.el7.x8664 to 3.10.0-514.21.2.el7.x8664 on my CENTOS server. SpamAssassin 3.0 and newer use instead of individual lists such as sc. I have run Surgemail on my CENTOS 7 server since a long time. Please use multi with urirhssub, as is the default in SpamAssassin 3.X. Some data sources are only available in multi.

Once you've got Mail::SpamAssassin::SpamCopURI installed, all you need is a rules file tellling SpamAssassin what SURBL lists to query. Remember to update Mail::SpamAssassin::SpamCopURI everytime you update SpamAssassin. A new version of Mail::SpamAssassin::SpamCopURI is released for every new release of SpamAssassin 2.6x. Using SURBLs with SpamAssassin 2.6x requires a patch to Mail::SpamAssassin::Conf be installed (it's available on CPAN) - the name of the CPAN distribution is Mail::SpamAssassin::SpamCopURI. They are very useful for detecting known spammy websites in Spam, while not requiring large rulesets containing list of spammer domains (such as sa-blacklist by WilliamStearns). SURBLs are DNS RBLs (blacklists) of domains. Introduction: SURBL - Spam URI Realtime Blocklists
