E.g.
https://stackoverflow.com/questions/9807909/are-email-addresses-case-sensitive
discusses this - including quotes from RFCs ...

The local part of an email domain has absolutely nothing to do with any
(local or non-local) user account - and who says that there are any user
accounts/logins (apart from root and so-called system users) on the mail

Yes, it *could* have something to do, and yes it actually may often be
the case but that's just a - intended or not intended - coincidence ....
