Trying to add a TXT record to verify domain ownership with Google on a virtualmin domain fails.
The error is: "Failed to save DNS record : Record name contains invalid characters"
An example verification TXT record looks like this: google-site-verification=djeA0O6_GZ0xQUtsQXJGZHiYPBXrEM_vGoNw5y42Ll4
I'm not sure what characters are invalid in that string. I've tried taking out the "=" sign, the underscores and also the dashes as a test and it still fails.
I was able to add the record by logging as root and adding a TXT record type to the zone in question via the BIND module.
