The only one that matters is RFC 5321, "The local-part of a mailbox MUST BE treated as case sensitive."

but in the real world you can use myname@domain.tld and mYnAmE@domain.tld for any mail-address and on most mail-systems there is a good reason why mailbox == email

But practically,

• What do we do with existing mailboxes User1 and user1?

the main question is WHO in the world starting with the same users in different cases?

without user@domain.tld "user1" and "User1" leads to collisions and MANY errors because 99 out of 100 users are not aware of case-sensitivity because it does not matter on most servers
