For a quick hack, you could try using tr:

/usr/cyrus/bin/deliver "echo $user | tr '[A-Z]' '[a-z]'"

But if anyone uses the user+mailbox format of email address, and has a 
mailbox that is not all lower-case, this won't work as expected (though 
I'd expect the mail would be delivered to the INBOX).
