Subdomain length limit exceeded

So I'm using an external company to host my email, and one condition they have that I have to meet is to have a very specific subdomain and then tag a TXT record to that particular subdomain, this shows them that I own the domain and I have the right to use this domain for my own email.

 

The issue is that the subdomain they require me to make is something like this:

 

7fc682377503bb95170602fe6e28621e8177892c.my.domain

 

So I try to add a subdomain in my GoDaddy control panel, and I get an error message saying:

 

Length overflow error.

 

Is there no way to create a subdomain like the one above - otherwise mailbox.org won't let me use my custom domain with them.

 

Many thanks for your time!

Re: Subdomain length limit exceeded

I've randomly fixed this problem!

 

I just needed to add a new TXT record:

 

7fc682377503bb95170602fe6e28621e8177892c <code provided by mailbox.org>

 

and that fixed it.  Didn't need to add a subdomain.
