RFC 822 requires the email address local-part to be case sensitive, see
section 6.1. RFC 2822 has this to say in section 3.4.1:

  The local-part portion is a domain dependent string. In addresses, it
  is simply interpreted on the particular host as a name of a particular
  mailbox.

On Unix systems, the local-part traditionally has been case sensitive,
and still is on a lot of systems.
