Testing our mail-system with your awesome Add-On, we found Reddoxx to use a different header than most other MTAs. This PR adds the header to the detection mechanism.
Example Header:
Received: from mail.example.com ( [0.0.0.0]) by mail.example.com
(Reddoxx engine) with SMTP-TLS id FFF000FFF00; Fri, 24 Apr 2015 23:59:59 +0200
Tested locally and found to be working. The only regression I can think of would lie in problems originating from adding the minus sign to the regex, so something like SMTPS-XYZ wouldn't match anymore.
