That's right, thanks! If I use the GNATBox specified as my external DNS Server, and if I have the DNS Server service setup with secondary servers, then the "match against MX" feature shouldn't be a single point of failure. Am I overlooking anything here?
The ability to list multiple DNS servers in the GNATBox's basic configuration would still be nice for GNATBox Pro users. Not only would the E-mail proxy be a single point of failure, but any other service you specify a domain name in could fail if the external DNS Server you specified went down (ie e-mail alerts). While using IP addresses is an option, it's not perfect. What if the domain name changes IP addresses, are you going to remember to update it in your GNATBox configuration? If this concerns you, you might want to add this to the Wish List section of the GNATBox Forums. -Brian -----Original Message----- From: Joe Matuscak [mailto:[EMAIL PROTECTED]] Sent: Friday, January 18, 2002 11:32 AM Subject: RE: [gb-users] SMTP Proxy On Fri, 18 Jan 2002, Brian Fort (Mushkin) wrote: > What happens when the external DNS server that you configure GNATBox for > goes down? Yup, that is a feature.

It would probably be a good thing if it were possible to configure multiple DNS servers. Joe Matuscak
