Title:
  signature generation is incorrect

Status in Module for DKIM signing and verification in Python:
  In Progress
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.
