Below is my 'courier' router and 'local_delivery_courier' transport

#courier router
authdaemon_lookup:
driver = manualroute
route_data =
domains = lsearch;/usr/exim/virtualdoms
address_data = ${sg{${readsocket{/var/spool/authdaemon/socket}{PRE . exim
$local_part@$domain\n}}}{([^=]+)=([^\n]+)\n}{\$1="\$2" }}
# note the space between "\$2" and }}

courier:
driver = accept
transport = local_delivery_courier
domains = lsearch;/usr/exim/virtualdoms
condition = ${extract{HOME}{$address_data}{1}{0}}

courier_bounce:
driver = redirect
domains = lsearch;/usr/exim/virtualdoms
data = ${if match{$address_data}{FAIL}{:fail:unknown user}fail}
allow_fail
fail_verify

# Transport for courier
local_delivery_courier:
driver = appendfile
directory =
${extract{HOME}{$address_data}}/${extract{MAILDIR}{$address_data}{$value}{Maildir}}/
maildir_format
maildir_use_size_file
delivery_date_add
envelope_to_add
return_path_add
#  user = exim
#  group = exim
maildir_tag = ,S=$message_size
quota_size_regex = ,S=(\d+)
quota = ${if match {${extract{QUOTA}{$address_data}}}{([0-9]+)S}{$1}{}}
quota_filecount = ${if match
{${extract{QUOTA}{$address_data}}}{([0-9]+)C}{$1}{}}
quota_warn_threshold = 85%
