See 'caseful_local_part = true'

As in:

shell_user:
driver = accept
caseful_local_part = true
check_local_user
transport = shell_delivery
cannot_route_message = Not one of our clients.

It is not available in every possible situation (nor should it be), but does
work in router/transport sets, which is where you specify needing it.

In the illustration above, our shell accounts (typically three only) rely on
mixed-case, and no 'folded' versions would ever be acceptable.

For the wider world of corespondents, be aware that insisting on case-senstivity
can add more grief than gain. local_parts are *supposed to be* at least
preserved and conveyed unaltered, if not treated distinctly, but typo's aside,
not all MTA will do so.

HTH,
