Very strangely as soon as my web centos went from .pro to normal it stopped sending email

Every email that goes out gets delayed and never sent, with the error

Host or domain not found, name service error for domain (domain name) that could be gmail.com microsoft.com anything same error,
type=MX record" Host not found, try again) I have the MX set up on these domains and it used to work when I had pro but now I don't have pro it quit sending email
