Hello All,

You may want to look at the below articles in relation to your failed MX
queries from your W23K DNS server.

It sounds like you are struggling with the EDNS0 problem, which can be
resolved via a simple command line syntax typed on the DNS servers. I
suggest that you look at the above articles.

Question
***********
What type of firewall and/or router separates the DNS servers from the
internet?
