Handle python bug 30681 for invalid date parsing

Following part of the code breaks since we are not catching TypeError and ValueError.

  754:          raw_body.append((encoding, raw_body_str, msg.items()))
  755:      except AttributeError:

Thanks for the report and the linked issue.
Since the PR was closed without being merged I submitted a new one to hopefully have this fixed upstream (python/cpython#22090).

Further I will how I can work around that issue. Feel free to submit a PR!

I have just committed a workaround for your issue.
Could you please test the latest master to see if that fixes it ?
