Yep. And what does RFC822 say about that? Page 14ff:

     3.4.7.  CASE INDEPENDENCE

        Except as noted, alphabetic strings may be represented in  any
        combination of upper and lower case.  The only syntactic units
        which requires preservation of case information are:

                    -  text
                    -  qtext
                    -  dtext
                    -  ctext
                    -  quoted-pair
                    -  local-part, except "Postmaster"

        When matching any other syntactic unit, case is to be ignored.
        For  example, the field-names "From", "FROM", "from", and even
        "FroM" are semantically equal and should all be treated ident-
        ically.

        When generating these units, any mix of upper and  lower  case
        alphabetic  characters  may  be  used.  The case shown in this
        specification is suggested for message-creating processes.

        Note:  The reserved local-part address unit, "Postmaster",  is
               an  exception.   When  the  value "Postmaster" is being
               interpreted, it must be  accepted  in  any  mixture  of
               case, including "POSTMASTER", and "postmaster".
