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!
