I have a client that is using ENOM for their domain name management, Google Business Apps for their e-mail hosting, and Network Solutions for their Web Hosting. The client purchased their domain name through CompanyX, which manages the domain name for them through ENOM. CompanyX was also hosting their web site up until today.
The client recently wanted to move ONLY their hosting to Network Solutions. So I developed their new site on the Network Solutions servers. When we launched, I asked CompanyX to change the DNS entries for their domain from CompanyX's servers to the DNS servers provided by Network Solutions.
When they did this, the client's e-mail (through Google Biz Apps) stopped working.
My question is why?
According to CompanyX, Network Solutions needs to add MX records on their end...but this does not make much sense to me since MX records (my understanding at least) are configured through ENOM...and since the MX records were already pointing to Google and should not have been changed, then the transition should have been seamless.
Do I have this wrong? Does the web host have to also add MX records somewhere on their end? Can this all be configured through ENOM?
