IMO - I would disable both 'Spam Domain Lists' and 'Spam Lists' in 
MailScanner.conf completely and let SpamAssassin score on these lists 
instead and move the 'trusted' RBLs into your MTA (e.g. 
zen.spamhaus.org) instead as this will significantly reduce the load on 
your MailScanner box.

The 'Spam List' lookups are serialised in MailScanner whereas they are 
done in parallel and asynchronously in SpamAssassin and are therefore 
way faster.
