Here it is, for Exim 4.10 and Cyrus IMAPD 2.1.5 using db3/db4-format
mailbox database. This configuration delivers the messages to Cyrus
IMAPD using LMTP over a TCP/IP socket, so the cyrus.conf file needs to
start lmtpd as "lmtpd -a" so the connection will be pre-authenticated
(given that, it is also important that the cyrus.conf file restrict
lmtpd to listening on 127.0.0.1 _only_, otherwise random users could
submit messages directly to lmtpd).


routers:

# look in the Cyrus IMAPD mailboxes.db file for local_domains local
# parts to be verified
local_user_verify:
   driver = accept
   domains = +local_domains
   local_part_suffix = +*
   local_part_suffix_optional
   condition = ${lookup{user.${local_part}} dbmnz {/storage/imap/mailboxes.db} {yes}{no}}
   verify_only

# rewrite local_domains local parts to be all lowercase
lowercase_local:
   driver = redirect
   redirect_router = local_user
   domains = +local_domains
   data = ${lc:${local_part}}

# deliver local_domains messages
local_user:
   driver = accept
   domains = +local_domains
   transport = local_delivery


transport:

# deliver messages to Cyrus IMAPD using LMTP over TCP/IP on the loopback
interface
local_delivery:
   driver = smtp
   protocol = lmtp
   allow_localhost = yes
   hosts = 127.0.0.1
