When you have another service scanning in front of Office 365, the proper thing to do is disable the Office 365 scanning altogether and (optionally) respect the verdict from the prior system. Once you do that, even with the SPF header, the mails will not go to the users’ junk folders.Anonymous commented
Agreed. We use proofpoint as our Spam/Filtering system and its annoying that O365 bascially fails every email sent to it because the sending system is always our proofpoint environment.
Is there a way to disable SPF checking on O365?
