We currently do lookups from the database to determine if a user is valid,
and then use the same lookup to do the actual delivery:



Router:



virtual_domains:

driver = accept

transport = virtual_delivery

domains = lsearch;/usr/exim/virtual_domains

condition = ${lookup pgsql{select maildir from email_account where
id='$local_part@$domain'}{$value}fail}

cannot_route_message = No such user here

no_more



Transport:



virtual_delivery:

driver = appendfile

maildir_format

create_directory

mode = 0600

user = popuser

directory = ${lookup pgsql{select maildir from email_account where
id='$local_part@$domain'}{$value}fail}

delivery_date_add = true

envelope_to_add = true



Is there any way to use a single lookup to accomplish the same thing ?
