Question:

How do I make a local reputation server zone (zone transfer) work with MailMarshal?

Procedure:

NOTE: This procedure may be necessary if you have purchased a zone transfer subscription from a blocklist provider such as Spamhaus.  

A local reputation server (DNS Blocklist server) runs as a DNS server in the local environment.  MailMarshal must be configured to use this DNS server as its primary DNS server in order to query the local copy of the reputation database.

This server will also be used as primary for all MX (delivery) lookups.

To set up MailMarshal:

• Open the MailMarshal Configurator or MailMarshal (SEG) 10 Management Console.
• Navigate to Array Properties | Sender Properties | Delivery (in earlier versions, Tools | Server & Array Properties, Delivery tab).
• Set the Primary DNS server to the IP address of the local DNS server where you configured the local copy of the blocklist zone.  Keep in mind that if you put an IP address in the secondary DNS server field, your blocklist checks will fail if the primary is unavailable.
• Additionally, set the Category script or host validation to use the appropriate blocklist host name (rbl-plus.mail-abuse.org is an example).

Notes:

Reference Q10737 for troubleshooting information.
