I'm not entirely sure what is the cause of this - notification emails from The Pension Regulator in UK (a government body overseeing pensions) have the destination email in upper case as part of the Message-ID. I don't know if the user has input their email address in caps when creating the account with TPR, and the system at TPR just preserves caps - or maybe their email software does that on purpose somehow. In all events, all email notifications from them go straight to the Junk folder. Do the standards really require a message id to be in all lower case?

I've enclosed one of the messages received here:
