esmtpd — The Courier mail server mail server ESMTP daemon
esmtpd {start}
esmtpd {stop}
esmtpd {restart}
esmtpd-msa {start}
esmtpd-msa {stop}
esmtpd-msa {restart}
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)
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)
automatically runs esmtpd-msa restart
/etc/courier/esmtpdThis 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
