The MUST in the draft may be a bit harsh.

Yes, s/MUST/SHOULD/ makes sense, e.g. if a MUA behind IMAP
wants to check signatures.  Editorial nit:  Splitting 3.5 in
subsections for the various "field types" could be a good idea.


Just a follow up to my previous message.

This section says the default is NO expiration.

That isn't going to work very well :-)

A DKIM message will no expiration will quickly moving into a reject
classification if other issues are found with the message.

This will be especially the case with key policy "t=y" testing flag
(section 3.6.1).

This section should make the x= mandatory for t=y key policies and
should recommend a short expiration for testing.

A long "testing period" with problematic DKIM messages should not be
tolerated.
