550 5.7.0 Message rejected per DKIM policy - 08:56am Nov 22, 2016 CDT - Hello! I`m trying to send an email to my customer, who has maildaemon as MTA. It drop my emails with the answer:
 dsn=5.7.0, status=bounced (host mail.example.com[] said: 550 5.7.0 Message rejected per DKIM policy (in reply to end of DATA command))

I have DKIM signing worked and tested succesfully on gmail.com, mail-tester.com, dkimvalidator.com, mxtoolbox.com, yandex.ru

Customers IT-team even don`t understand how DKIM works, so can you help me to explain them what should they do to avoid this behavior of mdaemon?..
