Thanks Mark and Brian. I'll try the suggestions.
My IP might have got blocked by CBL when testing mailman3 against a Gmail address. I have since removed it from CBL. I don't know how my IP got into the Outlook's block list. Maybe a used one. Will try DKIM signing and Microsoft programs.
Outlook and friends (Hotmail, Live, MSN. ...) can be a real pain. If you're not aware, start at <https://sender.office.com/>. Also, this requires patience. It may take several back and forth emails, some of which ask questions which have already been answered earlier in the quoted thread, but in every case where I've persisted, the block has ultimately been removed.
