[Exim] delivering mail to IMAP or POP3

Hello all,


I don't know how to write routers for mail delivering in exim 4. I want to
write two routers:
First router will check user from /etc/aliases and if the user exists there
then it will deliver mail by transport "local_delivery", otherwise it will
go to the second router which will deliver mail to imap by
"local_delivery_cyrus".
Does anybody have sample for it?
