I know its a lot.  So when one of the server on ( tries to send an email to Office 365 i get the following result:

Authentication-Results: spf=none (sender IP is;; dkim=none (message not

signed) header.d=none;; dmarc=fail action=quarantine;compauth=fail reason=000

Received-SPF: None ( does not

designate permitted sender hosts)

Can anyone explain to me why this is happening? The sender IP should be included in the record of

You have too many dns lookups in your spf record.  SPF has a max of 10 dns lookups so it appears that you reached the max before it reached


Take a deeper look at your SPF and try to clean it up.  IP addresses do not count as a look so convert to IP where you can.

@Michael_Larrivee Thank you so much. I was suspecting this might be the cause but i was never sure! I will reduce the includes and am sure that will solve the problem.
