In my control server the only other role installed is DNS and it has it's own domain.
So, let's say its called controlserver.com
I asigned ns1.controlserver.com in that server for the dns.
My questions are.
In my WEB server can I just use controlserver.com as HELO name for the email server?
And ns2.controlserver.com on my backup server that also has DNS role as redundancy ?
