If your exim supports it, you can try LMTP - I found that works well and also
gives temporary errors when cyrus is down, so exim will queue mail til its
back up.

To see if its availble, try

rasputin at lb:openldap$ exim -bV|grep Transports
Transports: appendfile/maildir/mailstore/mbx autoreply lmtp pipe smtp
                                                       ^^^^

If it is, you need to enable a local lmtp socket in cyrus.conf

  # at least one LMTP is required for delivery
  #lmtp         cmd="lmtpd" listen="imap.tenfour:lmtp" prefork=0
  lmtpunix      cmd="lmtpd" listen="/var/imap/socket/lmtp" prefork=0

and then just setup an exim transport to where the socket is:

lmtp_thru_socket:
  driver = lmtp
  batch_max = 20
  socket = /var/imap/socket/lmtp
  timeout = 45s

(you may need to add user=xx and group=yyy there depending on permissions)

finally tell exim to use that transport for your imap domains:

# send mail to local cyrus IMAP
cyrus:
        driver = accept
        domains = +imap_domains
        transport = lmtp_thru_socket
