How to use google._domainkey as hostname for DNS record when setting up DKIM.

When setting up DKIM for gmail Google uses the value google._domainkey as the DNS Host name (TXT record name).

This video shows the correct name being added in a control panel.

However when I use that value for my hostname DO adds my domain to it.

For example,

Google isn’t able to find this DKIM record with the wrong name.

How do I fix this?

Hi @thr333one,

When adding the google._domainkey as a TXT DNS record or any DNS record infact, this is always added to the domain, it’s just how DNS works

Example: I have a domain I want to add a TXT record to that domain. There are two possibilities, add it for the main domain - or like in your case add it for google._domainkey. When you add it for google._domainkey it automatically picks it up as being part of the main domain - That’s the proper way for a DNS TXT record or again any other DNS record to look like.

Please note that you might need to wait sometime before Gmail star seeing your DNS. Usually, the DNS propagation period can be up to 48 hours.
