transfer the mail server from my old web hosting service to digitalocean
Earlier I instructed my old web hosting service to map my domain to my IP address with digitalocean, they compiled and in addition, they suggested the mail server to the new IP as well.
Here is my two questions:
I think they still use their DNS to map the domain to my new IP, what should I do to start using DO’s DNS service with the minimum interruption to my web site?
Even though I didn’t install control panel such as VirtualMin or Zpanel, I might have done something that related to the installation of Roundcube, because now my home page was directed to Roundcube’s login page.
How can I verify that I have already a mail server installed? and how to instruct my old web hosting for the mapping? Maybe I just ask them to stop the service, since I intent to stop using their DNS service.
I hope I’ve made myself understood and thank you for the responses,
