Email already exist when changing email case

When I want to update my email address from 'john@…' to 'John@…', it will complain the email is already exist.

Should the comparison be case insensitive when doing the update?

This is a lot more complex than it appears, according to the RFC's that I've read (at least to my understanding), the first part of the email address (i.e. johndoe) is allowed to have uppercase and lowercase letters. However, it's not clear whether and johndoe@… are two different mailboxes.

The domain part of the address is only allowed a-z, -, and . in a case insensitive manner. However I feel that I must have missed an update to an RFC because you can now send emails with chinese characters in them.

Perhaps someone more versed in these RFC's can shed some light here.
