I could use some help. I have a customer that is hosting his own mail and web. However he wants to use our service as a backup mail provider.
Whats the best and accurate way to setup his domain records with the correct A and MX records
I currently have:
DOMAIN TYPE IP
Domain.com A hiswebserver.com
NS1.myserver.com A ip to mywebserver.com
NS2.myserver.com A ip to mywebserver.com
hiswebserver.com A ip to hiswebserver.com
Domain.com NS NS1.myserver.com
Domain.com NS NS2.myserver.com
Domain.com MX hiswebserver.com VALUE 5
Domain.com MX mywebserver.com VALUE 50
myserver.com = my webserver ( the backup mail provider)
hiswebserver.com = the customers webserver and mailserver
My concerns are on the NS records.
Should I have NS1.hiswebserver.com and NS2.mywebserver.com ?
