Lowercase enforced for TXT Record

I am configuring a mail server which has a requirment for mixedcase name for DKIM TXT Record as follows;

postal-NVi1wh._domainkey

However, Cloudflare enforces lowercase as the record does not resolve.

How do I resolve this?

I’m pretty sure DNS is case-insensitive, so the host is wrong.

Hey!

Thanks for such a quick response!

I did search it and found the same thing, but the service I am using provides mixed case values as the host.

I will message them to confirm!

Have an awesome day!
