Solution #00006288


All Email Security Gateways


On March 1st, 2013, NJABL or AHBL announced that they will be shutting down their IP reputation service. Customers should remove NJABL or AHBL lists from the Custom External RBLs option on their Email Security Gateways. Custom External RBLs can be added or removed from the BLOCK/ACCEPT->IP Reputation tab. Using NJABL or AHBL reputation lists on the Email Security Gateway will result in increased latency when processing email.

NJABL lists include:
  1. dnsbl.njabl.org
  2. dynablock.njabl.org
  3. combined.njabl.org
  4. bhnc.njabl.org

rhsbl.ahbl.org, dnsbl.ahbl.org, ircbl.ahbl.org.
