How do I disable DNSBLs in SpamAssassin?

If you don't want any DNSBLs used, add the following line to your local.cf file:

skip_rbl_checks  1

To eliminate the use of a particular DNSBL, set the score to zero for that test in your local.cf file. For example:

score   RCVD_IN_RFCI   0

score   RCVD_IN_ORBS  0

score   RCVD_IN_DSBL   0
