COURIERLDAPALIASD(8) Double Precision, Inc. COURIERLDAPALIASD(8)NAMEcourierldapaliasd - LDAP-based mail aliasing
SYNOPSIScourierldapaliasd {start}
courierldapaliasd {stop}
courierldapaliasd {restart}
courierldapaliasd {query} {source} {address}
DESCRIPTIONcourierldapaliasd 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".
CONFIGURATIONcourierldapaliasd 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.
