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)[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
/etc/courier/esmtpd
/etc/courier/esmtpd-msa
couriertcpd(8)[2], makesmtpaccess(8)[1].
