This is my first post so sorry for any generic formatting that I might be missing.
I'm trying to reduce the amount of configuration changes that our client would need to perform when we move their website around our servers. We plan to host the clients email with Google Apps and I was wondering if this would be a valid scenario to set up DNS to support a different mail provider if we decide to switch from Google to something else.
Basically what I have in mind:
I'd create two CNAME records (the example.com domain is my clients domain here):
pop.example.com -> pop.gmail.com
smtp.example.com -> smtp.gmail.com
and then the required MX records that Google provides would also be created for example.com.
Would this setup cover such scenario that when we want to switch server we only update the DNS and the client does not need any configuration changes on their side? (obviously we still need to keep using pop3 and smpt to keep it compatible but I'm only asking about the DNS changes here)
Thanks for any help
