@bgcarlisle I've found if your sending server is on something like Digital Ocean you will find yourself periodically blocked as other IPs in your range will trigger a block for spamming.
You then have to email MS support again and ask to be unblocked 🙄
They should provide notice in the email logs (Postfix or whatever) if you are blocked, but I have known them to just log as "email queued for sending" then drop the emails completely
