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

NAME

       makepercentrelay - Build a list of %-relayed domains

SYNOPSIS

       makepercentrelay

DESCRIPTION

       makepercentrelay reads /etc/courier/esmtppercentrelay.dir and creates /etc/courier/esmtppercentrelay.dat which is a binary database file.
       The files /etc/courier/esmtppercentrelay and /etc/courier/esmtppercentrelay.dat specify a list of "percent-hack" domains.
       /etc/courier/esmtppercentrelay is a plain text file, containing one domain per line. The Courier mail server loads the contents of
       /etc/courier/esmtppercentrelay into memory, so if you have a lot of domains, you will want to use the binary database file. The
       makepercentrelay command reads /etc/courier/esmtppercentrelay.dir, which can be either a plain text file itself, or a directory containing
       plain text files. All files in the subdirectory are concatenated, and the binary database file is created from the result.

       the Courier mail server can use both /etc/courier/esmtppercentrelay and /etc/courier/esmtppercentrelay.dat at the same time. Usually you
       would put a couple of your most frequent domains in /etc/courier/esmtppercentrelay, then put the rest in
       /etc/courier/esmtppercentrelay.dir, and use makepercentrelay to turn it into a database file.

       "percent-hack" domains are a list of domains for which the Courier mail server accepts mail via ESMTP addressed as
       "local%percent.hack.domain@local.domain", where "percent.hack.domain" is a domain found in /etc/courier/esmtppercentrelay or
       /etc/courier/esmtppercentrelay.dat, and "local.domain" is any domain found in /etc/courier/locals. The Courier mail server removes the
       local domain, and rewrites the address as "local@percent.hack.domain", then attempts to deliver it.

       The percent hack applies only to mail received via ESMTP. The Courier mail server does not check this list of domains if the message is
       received via any other way (such as by running /usr/bin/sendmail directly from the command line). "percent.hack.domain" would likely to be
       a domain that the Courier mail server knows how to handle via some other means. It might be an entry in /etc/courier/aliases, or an entry
       in /etc/courier/esmtproutes.
