GMail DMARC : 'ezmlm warning' - '550-5.7.1 DMARC policy. ... of google.com domain' not considered an authorized sender ?

Hi Florian -

I am doing so hereby.

I haven't got any more of these failed-to-deliver messages since:
libc-help-help	| Inbox, To Jason |
   ezmlm warning - .1 DMARC policy. Please contact the administrator of
   google.com domain 550-5.7.1 if this was a legitimate mail. Please	16/11/2016

I just thought I should report it because it looked like all is not
quite OK with
authenticating your email sender to google.

Thanks & Regards,
Jason
