Can you recommend me a DNS configuration for this setup?

I have setup a CPanel server where I will host 2 domains that will be used for sending bulk emails of a government agency. However I would like to be able to change the IPs in case any of the IPs become blacklisted. The problem comes from the fact that I am using a third party DNS server. How can I do to have this work with the 2 domains that I will use. Is there some kind of domain delegation that I can do?

  Can you go into detail in terms of why you think there is an issue with using a 3rd party DNS server? This wouldn't cause any problems at all. Simply create your forward DNS records at your 3rd party DNS server, meaning assign each additional IP an A record to point to a hostname. Ask your host to configure the rDNS for each IP to match what you've set at the 3rd party DNS server, and then in: Exim Configuration Manager Enable both options: Reference /etc/mailhelo for outgoing SMTP HELO Reference /etc/mailips for outgoing SMTP connections Save Then setup your first IP, in /etc/mailips:
  *: 1.1.1.1
  and in /etc/mailhelo:
  *: mail1.domain.com
  If 1.1.1.1 gets blacklisted, you would simply change the IP and hostname in the files shown above.
