All MTAs are allowed to do what they want with the local part regarding
case when they are the final delivery MTA (ie. the MTA running on the
destination host). The intermediate MTAs are required to preserve the
case of the local part because they don't know if it is significant to the
actual delivery host.
qmail works correctly.
When qmail is NOT the delivery host, it perserves the case of the local
part and sends it on.
When qmail IS the delivery host, it squashes the case of the local part of
the address to lower case because for qmail the case of the local part is
irrelevant when determining the mailbox into which it must deliver the
message. It was designed that way for the reason that Russ stated.
