Answers.Text: I have just seen this exact problem for the first time this week (of course, I've seen variations of it as well).  I think Microsoft have just switched something on, so that if you are receiving an email using a Microsoft product like Outlook and the email was sent using a Microsoft based email address through CiviCRM then you'll get this annoying message.  The problem in this situation is whether you can update SPF/DKIM ? We see this with Office365 email addresses...

Answers.Text: @Jporter Does the use of spf.protection.outlook.com mean that you *send* email with an Microsoft email (until now we focused  on receiving)? In that case, Microsoft can help you with the correct settings.

  Welcome in the world of preventing spam. Your email is rejected by a Microsoft service, so Microsoft sets the rules. According to [their documentation](http://www.office365mvps.com/2016/09/this-sender-failed-our-fraud-detection-checks-and-may-not-be-who-they-appear-to-be), the cause may be spoofing or, more likely in your case an *incorrectly configured Sender Policy Framework (SPF) record*.
  
  You can reproduce this problem by sending a single email to an outlook address by using just the send mail action.
  
  My assumption is that you sent your email directly from the server where CiviCRM is installed by using the *mail()* or the *sendMail* option in *Settings - Outbound Mail* . But your is not registered according to the SPF framework to be a legitimate email sender for your domain.
  
  You can try to send the emails using SMTP server of your ISP (configure *smtp* in Outbound Mail). Another option is to add an SPF record to your DNS. More information at [OpenSPF](http://www.openspf.org/SPF_Record_Syntax).
  
  However, SPF is not the only countermeasure to discourage spam. The other is [DKIM](https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail).
  
  If you are sending large volumes of email you can consider using a specialised SMTP provider.

  Try sending you mailings to the email address on <https://www.mail-tester.com> and checking the results (just folw the big instructions on the page) - ain't no good if you get a rainy day - you need bright sunshine and birds singin'.
  
  MSOutlook servers also often require the DMARC record set (it' tell you how).
  
  SPF and DKIM are also good, but check the report.
  
  SPF is easy to set up (just find some docs) - it's just registergint he address of your outgoing server - the report will also give you some details for that.
  
  Good luck!
