hashing when using the relaxed canonicalization - Thanks to Martin Pool for
the patch (LP: #587783)

Status in “pydkim” package in Ubuntu: Fix Released
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.
