Domain DNS error

i have configured my email server correctly all mails incoming and outgoing all are perfectly fine but when i open
Server Configurations => DNS records i found this warning
“Warning - errors were found in this domain’s DNS records : This domain has email enabled, but none of the MX records point to it. Either the MX records should be corrected, or the email feature disabled if mail is hosted externally.”
i dont know please help me to remove this warning.

I have the same issue when using a domain with mx records with the same suffix on other servers.
I am asking the forum on how to change the default suffix for mx record on specific Server template/plan.

Be default it does so if your domain as that suffix already used on other servers it fails since the records have different ips.
