Are MX record names important?

When creating MX records for a domain, is it important what they are called?

I want to manage email through a remote service and have added the appropriate destination and priority. The service that is used to manage the domain (cpanel) does not allow the MX record name to be called @ so I gave it a name like mx1.mydomain.com

Is this is a problem when setting up MX records?

The owner name is crucially important as it has to match the right-hand-side of the email address.

Eg [email protected] -> look up example.com MX, [email protected] -> look up bar.example.com MX.

If the MX exists at mx1.example.com it will only serve any purpose for mail sent to addresses ending with @mx1.example.com (which I'm guessing is not the intention to have).

As for @, this is a special value in the "master file format" (standardized plain text representation of DNS data) which is a shortcut for "current origin".
What you need to focus on is that you want to add an MX at example.com. (presumably), not how one might achieve that in some different system than what you are dealing with. If you are working with a GUI, it will come down to how that interface was designed to work. If it's not sufficiently intuitive that you can work out how to do it, you would have to consult the documentation for this specific interface.

Thank you - that helped me troubleshoot it some more and get to the root of the problem. There were two mechanisms for adding MX records, one required an alphanumeric prefix, the other had no options for a name (so I assume under the hood it has an @ present)

You can also give the name for MX record as domainname.com. (the period character at the end is required), replace with your primary domain hosted in CPanel.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
