The acronym "SMTP" appears numerous times in the DKIM RFC, and it is a normative reference.
As far as I can tell, it's a normative reference because RFC 6376 imports ABNF from RFC 5321. We also said that you could reject a verification failure inline, which has SMTP implications. But that's it. If not for those, though, it probably could've/should've been informative.
To wit: A message sitting in a message store can be DKIM-verified. You don't need any part of the SMTP session to do that.
