NAME

   courierldapaliasd - LDAP-based mail aliasing

SYNOPSIS

   courierldapaliasd {start}

   courierldapaliasd {stop}

   courierldapaliasd {restart}

   courierldapaliasd {query} {source} {address}

DESCRIPTION

   courierldapaliasd supports mail address aliasing, as implemented by
   makealiases(8)[1] but using an LDAP directory instead of a GDBM or a DB
   database. The term "aliasing" refers to substituting one or more
   addresses for another address. A one-to-one substitution results in the
   Courier mail server accepting mail for one address, and delivering the
   mail to another address. A one-to-many substitution results in the
   Courier mail server accepting mail for one address, and delivering a
   separate copy of the message to every address defined by the alias.

   makealiases(8)[1] uses a GDBM or a DB database to perform the aliasing
   function.  courierldapaliasd uses an LDAP directory instead.

   "courierldapaliasd start" runs the courierldapaliasd process in the
   background, and should be executed at system startup.
   "courierldapaliasd stop" stops the background process.
   "courierldapaliasd restart" restarts the process, and rereads the
   ldapaliasrc configuration file to pick up any changes.
   courierldapaliasd restart must be executed in order for any changes to
   ldapaliasrc to take place.

   courierldapaliasd runs in the background and opens a persistent
   connection to the LDAP directory, and checks every recipient address
   using the persistent connection.  courierldapaliasd automatically
   starts an adjustable number of multiple processes. With persistent
   connections being used, this allows alias checking to be as efficient
   and quick as possible.

   "courierldapaliasd query source address" is a diagnostic tool. It
   requires that courierldapaliasd must already be running in the
   background; it sends a query for address to the background process, and
   prints the result. Like makealiases(8)[1], it is possible to create
   aliases that are accessible only to certain sources of mail, like
   "esmtp" or "local". The "source" argument specifies the source of the
   address, such as "local", "esmtp", or "uucp".

CONFIGURATION

   courierldapaliasd requires OpenLDAP client libraries, and is installed
   automatically if OpenLDAP client libraries are available at
   installation time. The default ldapaliasrc configuration file contains
   additional instructions for configuring LDAP-based aliasing.

FILES

   /usr/sbin/courierldapaliasd

   /etc/courier/ldapaliasrc
