Problem with Hotmail/Outlook.com parsing in SpamCop Reporting Help Posted November 14, 2017 Understood, and thanks for the suggestion, but I really think that Mr_Wizard is experiencing exactly the same problem as me, and mailhosts isn't the answer. From a selfish point of view, and being the OP, mailhost reconfiguration doesn't resolve my issue, and I strongly suspect it doesn't resolve the issue for anyone who uses outlook.com. I also use spamcop for gmail and a personal webserver, and they work great, and I do occassionally reconfigure these too. It's just outlook.com that gives me problems, yet no one has suggested a solution (except for my workaround). So with me re-asking for a resolution to the outlook.com header issue, I don't think this a "spiral into never-never land". In fact I think it is exaclty the point of my original question.
