Adding a Trusted DNS Black List

Before adding to the Trusted DNS Black List for a domain, be sure that it has been added to the system level DNS Black List, found at System > DNS Black Lists.

DNS Black List selection will only display items that are enabled. This option is set in the System > DNS Black List. By default all items added to the System > DNS Black List are enabled.

Note: Disabling a an item in the System > DNS Black List will automatically remove it from the Connection Checks or Trusted DNS Black List. Should the item be enabled at a later date it will automatically re-enable the list in Connection Checks or Trusted DNS Black List.

Caution: A match made to the Trusted DNS Blacklist will automatically be deleted

DNS Black Lists. Select a check box corresponding to the trusted DNS Black List you want to add.
Enabled. This column displays whether or not the black list is enabled.
Server. This column displays the domain name or IP address of the DNS server to contact for black list queries. This field contains an asterisk (*) by default, which indicates that the default IMail Server DNS is used for black list queries, where it relays the DNS query to the DNS server for the black list. Using the asterisk eliminates the need to enter the IP address or domain.
Query Domain. This column displays the domain to query in the zone file. This name usually matches the server domain name. However, sometimes a black list will contain multiple zones to query on the same server. When this happens, the server name and the query domain will be different. The only way to know this is to read the documentation for the black list being used.
