It's up to the receiving MTA whether mail addresses (which need not
correspond to usernames) are case sensitive or not. In any case, if
it's selectable behavior, which it is with sendmail, there's no bug.
You might argue that it has the wrong default value, but it's settable
to whatever you want.

With enough effort, you _can_ get sendmail to treat local username

on the local mailer, but also tweak the alias file definitions to
not lowercase everything). The case of the localpart of _remote_
addresses preserved (though I suppose you _could_ break this in your
sendmail.cf if you were completely stupid).

True. Anyway, out of curiosity, what happens (assuming you're
running sendmail with the default config) if you have two users, JOHN
and john? (Ok, this is stupid to begin with, but it can happen...) The
user JOHN simply can't receive any mail, even locally?
