Answer 1: Yes, it is RFC compliant. The RFC states that a host may,
at its option, differentiate between local parts based on the case.
Therefore, any MTA that sends mail MUST preserve the case of an
address that is presented to it.
And indeed, qmail does just that. However, when it delivers mail, it
never does so to a username with upper-case letters.

Answer 2: Because too many users think that email is case-insensitive,
and happily send mail in either case.

Answer 3: It does NOT alter the case of a mailbox username. Case is
ignored when matching a user name or extension. The case of the
username is always preserved, however.

Answer 5: Use qmail-users and run qmail-pw2u with the -u flag.
