I guess there's also the dkim canonicalisation. Mine was

There's your problem.
If you use relaxed instead of relaxed/relaxed, the unspecified body

DKIM canonicalizations are proof that DKIM was devised by people without
useful real-world email knowledge. None of the defaults make sense and
the "relaxed" canonicalizations are grossly inadequate for dealing with
entirely reasonable and harmless message modifications.
