AFAIK spamassassin will only do the lookups on rbl's that are enabled.
If you don't want to do any lookups, I think you can set dns_available no in
mailscanner.cf, but that will disable the most reliable spam checks that
Do you just want to disable certain rbl's or all of them?
MailScanner is like deodorant...
You hope everybody uses it, and
you notice quickly if they don't!!!!
