Is there a preferred list of rbl sites one can use in postfix. I keep getting the following on the following:
warning: 21.27.134.89.zen.spamhaus.org: RBL lookup error: Host or domain name not found. Name service error for name=21.27.134.89.zen.spamhaus.org type=A: Host not found, try again Feb 19 14:45:44 mmtlnx postfix/smtpd[31220]: warning: support for restriction "reject_maps_rbl" will be removed from Postfix; use "reject_rbl_client domain-name" instead Feb 19 14:45:45 mmtlnx postfix/smtpd[31221]: warning: support for restriction "reject_maps_rbl" will be removed from Postfix; use "reject_rbl_client domain-name" instead Feb 19 14:45:45 mmtlnx postfix/smtpd[31221]: warning: 18.101.3.83.zen.spamhaus.org: RBL lookup error: Host or domain name not found.
