It works for me:
Code:
zmprov gacf | grep zimbraMtaRestriction
zimbraMtaRestriction: reject_rbl_client zen.spamhaus.org
zimbraMtaRestriction: reject_rbl_client psbl.surriel.com
zimbraMtaRestriction: reject_rbl_client dnsbl.dronebl.org
zimbraMtaRestriction: reject_rbl_client bl.spameatingmonkey.net
Code:
cat /var/log/zimbra.log | grep spamhaus
