esmtpd - The Courier mail server mail server ESMTP daemon

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

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
