qmail Doesn't Deliver to Users Whose Usernames Contain Uppercase Letters

qmail converts the entire "local part"—everything before the @ in an address—to lowercase. The man page doesn't come out and say that, but the code does. The fact that it ignores users with uppercase characters is documented in the qmail-getpw man page.
