COURIERLDAPALIASD(8)					      Double Precision, Inc.					      COURIERLDAPALIASD(8)

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.

NAME

       esmtpd - The Courier mail server mail server ESMTP daemon

SYNOPSIS

       esmtpd {start}

       esmtpd {stop}

       esmtpd {restart}

       esmtpd-msa {start}

       esmtpd-msa {stop}

       esmtpd-msa {restart}

DESCRIPTION

       The command "esmtpd start" runs couriertcpd in the background, listening on the SMTP port.  couriertcpd will run courieresmtpd in response
       to connection requests.

       The command "esmtpd stop" stops the couriertcpd daemon, shutting down the ESMTP service.

       The command "esmtpd-msa start" starts the server on the message submission port, port 587. "esmtpd-msa stop" stops it. The difference
       between esmtpd and esmtpd-msa is that the latter is set up for additional processing as defined by RFC 2476 (mainly that the messages will
       have the Message-ID: and Date: headers added, by default).

       Normally, makesmtpaccess(8)[1] automatically runs "esmtpd restart", in order to reread the /etc/courier/smtpaccess.dat access file, so you
       don't have to do it manually, yourself. Similarly, makesmtpaccess-msa(8)[1] automatically runs esmtpd-msa restart

FILES

       /etc/courier/esmtpd
	   This configuration file initializes various settings for courieresmtpd.

       /etc/courier/esmtpd-msa
	   This configuration file initializes the settings for courieresmtpd when invoked by esmtpd-msa. Note that this file is used to override
	   the settings /etc/courier/esmtpd. The command "esmtpd-msa start" first reads /etc/courier/esmtpd, then afterwards
	   /etc/courier/esmtpd-msa. Any settings in esmtpd-msa override the corresponding settings in esmtpd
