[Bring Your Own DKIM] A private key that's used to generate a DKIM signature.

[Bring Your Own DKIM] A string that's used to identify a public key in the DNS configuration for a domain.

[Easy DKIM] The key length of the future DKIM key pair to be generated. This can be changed at most once per day.
