Use the following in the router section of your exim.conf file:

# This router matches local user mailboxes.

localuser:
  driver = accept
  domains = @ : localhost
  check_local_user
  transport = local_delivery


# Rewrite local-part to lowercase
lowercase_cyrus:
   driver = redirect
   domains = +local_domains
   redirect_router = cyrususer
   data = ${lc:${local_part}}


# This router matches cyrus mailboxes.

cyrususer:
  driver = accept
  no_check_local_user
  transport = cyrus_delivery
