MX records - same mail server on root and sub-domain name - possible?

i tried to search internet but not found answer.

On one domain name, in root and in a sub-domain name i have MX records pointing to the same mail server with same prios:

domain.com     in MX 10 mail-1.com
abc.domain.com in MX 10 mail-1.com

Zone was released without any errors, and now from external DNS check when i DNS-reverse: abc.domain.com i get this result:

abc.domain.com IN MX 10 mx.abc.domain.com

Crazy, isnt it? am i missing something here?

thanks for help!

MX record is a type of resource record in the Domain Name System that specifies a mail server responsible for accepting email messages on behalf of a recipient's domain

So answers to your points:

  • of course, mail servers can handle multiple different domains. I am certain that ASPMX.L.GOOGLE.COM is set as MX record for thousands of domains
  • priorities don't matter here, thyy are used in case you have multiple MX records for the same domain
  • you need MX for subdoman only if you intend to receive emails for [email protected] addresses

(Troubleshooting any issues/mismatch will be difficult without real domain name)
