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 supported this idea ·Anonymous commented
Same here, we use a thrid-party spam guard and every mail sent to us, displays an spf error in the email header. Please provide us with a solution.
