Hi Guys. So my SPF Records looks like the following:
v=spf1 mx ip4:91.198.79.139 ip4:217.26.51.230 include:spf.surveymonkey.com include:_spf.salesforce.com include:spf.protection.outlook.com include:et._spf.pardot.com include:aspmx.pardot.com include:spf.mail.hostpoint.ch include:spf.abacuscity.ch ~all
I know its a lot. So when one of the server on hostpoint.ch (217.26.49.146) tries to send an email to Office 365 i get the following result:
Authentication-Results: spf=none (sender IP is 217.26.49.146)
smtp.mailfrom=p12.server.hostpoint.ch; noser.com; dkim=none (message not
signed) header.d=none;noser.com; dmarc=fail action=quarantine
header.from=noser.com;compauth=fail reason=000
Received-SPF: None (protection.outlook.com: p12.server.hostpoint.ch 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 hostpoint.ch....

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 include:spf.mail.hostpoint.ch
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.
