Comment (by asaifm):

 Hello @dd32,
  Thanks for your response. The plugin that uses `wp_update_user` does not
 alter the casing. It simply passes the email address to it and does not
 perform any checks on the similarity of the old and new addresses.

 Ok, I have seen your note in [https://tools.ietf.org/html/rfc5321] now. I
 am not sure how to take this further, so feel free to close the ticket if
 you prefer to stick to the RFC.
