I further tracked down the empty line. Seems like something is going 
wrong with the line termination.

I configured Exim to deliver using LMTP over TCP/IP instead of using a 
socket:

-- exim.conf:
local_lmtp:
   driver = smtp
   protocol = lmtp
   service = lmtp
   hosts = localhost
   hosts_override
   gethostbyname
   allow_localhost

-- cyrus.conf:
   lmtp		cmd="lmtpd -a" listen="lmtp" prefork=0
#  lmtpunix	cmd="lmtpd" listen="/var/imap/socket/lmtp" prefork=0

Then I attached tcpdump/ethereal to the loopback interface. The 
communication between Exim and Cyrus is shown below.

The lines up to and including "Received: ... +0200" are terminated using 
\r\n. The following lines are terminated using \r\r\n.
