First make sure courier and exim use the same database library, in my
case libdb.so.1. For details, see courier and exim docs.

Create a user for the courier system, mine is
vmail:*:16:12:vmail:/home/vmail: This is explained in the courier docs.

Then you can use a director like this:

vmail_smartlist:
  driver = smartuser
  local_parts = dbmnz;/etc/userdb.dat
  home_directory = "${if match{${extract{3}{|}\
                      {${local_part_data}}}}{^mail=(.+)\\$}{$1}fail}"
  transport = vmail_delivery

Note the 'dbmnz'. This tells exim not to append a zero to a lookup key.

This is the transport:

vmail_delivery:
driver = appendfile
maildir_format
create_directory = true
directory_mode = 0700
current_directory = /
check_string = ""
prefix = ""
suffix = ""
directory = ${home}
return_path_add
envelope_to_add
group = mail
user = vmail

Hope this gets you going,
