Same here. Started a few months ago on my S9. All emails sent to Gmail bounce back with this error:
Messages missing a valid messageId header are not 550 5.7.1 accepted.

I have had the same issue recently. My Samsung A50 and Samsung Tablet will no longer send messages to Gmail accounts. Both are using the native Samsung mail app. However I can send message from my PC using outlook no problem.
Did you ever get a resolution to the issue?
