Status in “pydkim” package in Ubuntu: Confirmed

Bug description:
I think the signatures generated by python-dkim are incorrect:

In Relaxed header mode the 'DKIM-Signature' header should be canonicalized before hashing <http://tools.ietf.org/html/rfc4871#section-3.7> but currently it is wrong in two regards: it is hashed without case-folding and with non-canonical whitespace.
