Good Day,

There is a Mail Security Server on the DMZ of a network with
checkpoint firewall in between DMZ and Int Network.
After looking at the logs the MSS looks to a server for DNS which
doesn't host DNS.
It seems that when the rule is enabled for the MSS to query this
server inbound mail is fine but when disabled there is no inbound
mail.

any suggestions?
