Situation is that I am moving my mail server from the server to a third party host for my hosting company.
The domain ([mysite.com](http://mysite.com)) is bought through Yahoo. The name servers are registered through there so i have [ns1.mysite.com](http://ns1.mysite.com) and [ns2.mysite.com](http://ns2.mysite.com) pointed to my server.
Now, if [company.com](http://company.com) is hosting my email, what entries need to be updated? CNAME and MX entires need to forward [mail.mysite.com](http://mail.mysite.com) to the new server along with the MX entries need to be changed.
What path does a client requesting [mysite.com](http://mysite.com) result with DNS entries?

Create an A record for [mail.mysite.com](http://mail.mysite.com) with the IP of the company hosting your mail server(or whatever new server is hosting your mail)
Create an MX record pointing to [mail.mysite.com](http://mail.mysite.com)
CNAMEs are just aliases that point at other host names…
A Record 10.10.10.25 = [mail.mysite.com](http://mail.mysite.com)
MX Record = [mail.mysite.com](http://mail.mysite.com)
A CNAME example would be…
CNAME [webmail.mysite.com](http://webmail.mysite.com) = [mail.mysite.com](http://mail.mysite.com)

What would the A entry be for if there is a CNAME?
Also, does this need to go on Yahoo Domains or on the main server [mysite.com](http://mysite.com)’s dns entries?

A records point hosts at IPs
CNAMEs point hosts at hosts
Whatever company you registered the domain with lets you pick DNS servers…you need to add the A record/MX record to those name servers you pointed your domain at…

Thanks. That fixed it. The Yahoo settings were right but all the MX entires needed to be added to the server where our own nameservers are hosted.
