Hmmm. I think this may have something to do with the method being used to get
the messages from Exim to Cyrus.
There are (at least) four ways to do that:
1) Exim can pipe the messages to the Cyrus "deliver" command.
2) The Exim LMTP transport can deliver to Cyrus' lmtpd over a Unix socket.
3) The Exim LMTP transport can deliver to Cyrus' "deliver" command via a pipe.
4) The Exim SMTP transport (in LMTP protocol mode) can deliver to Cyrus' lmtpd
over a TCP/IP socket, with or without SMTP authentication.
I am currently using method 4. I don't have time to test the different methods
to see how they handle caseful local parts, and there could certainly be a bug
in Exim in the LMTP transport. When I first set up Exim 4.x, I was using method
3 and most definitely had to lowercase local parts before sending them to Cyrus.
