Thanks for this comment. I also went down the same path. However, for me mails to Microsoft (outlook, live etc) don't seem to be working.

You said - > I then spent a couple of days setting up the various DMARC MTA-STS policies etc. [most of that time involved looking up what they were and why I needed them!]

Can you tell me how you did this? It'll be a bit help!

Sorry. It was a few months ago, so I can't remember the intricate details. And my config [as I said previously] was slightly out of the norm. But I did use this site which checks the state of your MTA-STS config and gives you a few clues as to what you need to twiddle:

EDIT: have you tried the MIAB forums? They're quite a helpful bunch:

Thanks! Going through the forum helped. Had to reach out to Microsoft and request them to unblock the IP.

Interestingly, https://blog.paranoidpenguin.net/2015/01/outlook-com-is-sile... posted on HN today indicates that Outlook is discarding mail from low reputation senders after accepting them. Perhaps that's happening to you?
