Correct.
In this case, you already have all the information you need, because
subtype specification is MANDATORY. There are no default subtypes.
ok.
SA must flag the email, because it is not compliant to RFC 822.
Not true.
As has been said before, SA is not an RFC-compliance auditing tool. For
SA, RFC compliance checks are only useful insofar as non-compliance is an
indicator of spam.
The omission of a MIME Content-Type may be a spam indicator, or it may
simply be an indicator of a sloppy MUA implementation that takes advantage
of Postel's principle.
