Is DKIM record same as TXT?

I am trying to use Apple icloud+ emails with my custom domain.

At one point they give you a list of records to create, MX, TXT, SPF…and the last one is DKIM.

There’s no DKIM in the dropdown list of record types. Will a CNAME do the same? I’m lead to believe that it might because it lists:


Host sig1._domainkey

I’m not sure if the host “sig1._domainkey” is supposed to resolve to “” but I assume so since it’s a CNAME type?

How do you guys deal with DKIM?

It (the public key) should be a TXT resource record according to Was ist ein DKIM-Eintrag? - united-domains .
