Hotmail / Outlook (Exchange?) mails not parse able leading to failed decryption

Users regularly run into problems if sending mails from accounts hosted a Hotmail or Outlook. See issues #211 (closed), #246 (closed) and #331 (closed) for details. This might be due to the use of MS Exchange.

We should verify this, and invent and introduce a better approach to this problem, as the current technique, checking the X-OriginatorOrg for matching domains is very brittle, at least.

Leaving this without a milestone for now, as I'm not sure right now, who'll take care of this and when etc.

Some headers, which might be helpful to find a more generic solution:
