For a really lightweight solution, just use maildir directories.
Then exim doesn't need any sort of database at all, and you can use
courier-imap's userdb for the POP/IMAP passwords.

Here's mine (I don't think it can get much simpler). In exim:
# router
localuser:
driver = accept
local_part_suffix = +* : -*
local_part_suffix_optional
local_parts = dsearch;/var/spool/vmail
transport = local_delivery
cannot_route_message = Unknown user
#transport
local_delivery:
driver = appendfile
directory = /var/spool/vmail/$local_part
maildir_format
delivery_date_add
envelope_to_add
return_path_add
group = mail
And I use this script to create the mailboxes and courier-imap
accounts:
#! /bin/sh
#
# usage: userdb-adduser username password
#
mkdir /var/spool/vmail/$1
touch /var/spool/vmail/$1/maildirfolder
mkdir /var/spool/vmail/$1/{new,cur,tmp}
chmod -R 700 /var/spool/vmail/$1
chown -R mail.mail /var/spool/vmail/$1
/usr/lib/courier-imap/sbin/userdb $1 set home=/var/spool/vmail mail=/var/spool/vmail/$1 uid=8 gid=12
/usr/lib/courier-imap/sbin/userdbpw <<EOF | /usr/lib/courier-imap/sbin/userdb $1 set systempw
