esmtpd - The Courier mail server mail server ESMTP daemon

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

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

       The command "esmtpd-msastart" starts the server on the message submission port, port 587. "esmtpd-msastop" 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 "esmtpdrestart", 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-msarestart

       /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-msastart"
           first reads /etc/courier/esmtpd, then afterwards /etc/courier/esmtpd-msa. Any settings in esmtpd-msa
           override the corresponding settings in esmtpd
