Yes it is, and its also just as trivial to give each one you spin up a DKIM, so by verifying that you arent getting any extra protection if the email must be verified.

The main benefit of DKIM is email spoofing, where someone sends out emails without any intention of being able to receive replies since they dont actually own the domain, they just pretend to.

Therefore if an email must be verified before you can use an account then verifying DKIM doesnt offer your server any additional protection.
