First of sorry i m new in all this so forgive me if i act like a noob
The issue one of my client is just migrate from another hosting to mine now every thing is fine except one thing which is, there is one subdomain which is mail.clentdomain.com but this subdomain is not listed in it's sub domain list.
Now the issue is that this sub domain has some other IP for exp
mail.clientdomain.com = 18.104.22.168
when i try to dig it the very first line was
mail.clientdomain.com is an alias for mail7.problem.net.
mail7.problem.net = 22.214.171.124
But my name server IP is different from it. How can i fix this?
I check all the stuff on my side like there is nothing wrong in MX entry neither there is any sub domain listed.
hi ..just to be clear a subdomain is something like xxx.mail.subdomain.com
(where the xxx is the host and mail.subdomain.com is the subdomain)
if this is not your case i.e. you are just trying to find out whats going on with the host 'mail.clientdomain.com' ..the the first thing to look is the registrar and see where the nameserver is pointed to for that domain (it should to your name server) ..if not then you can:
1. either have the customer change the nameserver entry on the registrar to point to yours and you can adjust your IP to that host
2. have whoever controls the nameserver the registrar is delegating to - to point that host to the right IP address
Does your client want to use your email server or continue using the one that he used to?
If he wants to use your servers, then assuming that the MX record is pointing to mail.clientdomain.com , just go ahead and change the IP for the sub-domain mail to your mail server IP. And ask the registrar who controls the domain name to point the domain to your name servers.
