commit f0b0f71e5fa2b7d6048eb32ebd31f8d3a2fc4278
Author: meskio <meskio at torproject.org>

    Don't look for X-DKIM-Authentication-Results headers
    
    opendkim produces 'Authentication-Results' header to indicate if the
    dkim signature is valid, but nothing in our current infraestructure
    produces or reads X-DKIM-Authentication-Results. Check only for
    'Authentication-Results' so an attacker will not be able to fake an
    email without really comming from an authorized provider.
