NAME
courierpop3d - The Courier POP3 server SYNOPSIS
/usr/sbin/couriertcpd {-nodnslookup} {-stderr=syslog} {110} {/usr/lib/courier/courier/courierpop3login} [modules...] {/usr/lib/courier/courier/courierpop3d} {./Maildir} DESCRIPTION
This is a simple POP3 server for Maildirs. Note The couriertcpd, courierpop3login, and courierpop3d modules may be installed elsewhere than indicated here. courierpop3login is usually started by couriertcpd. It already expects that a POP3 client is connected to standard input and output, presumably via a network socket. courierpop3login reads the POP3 userid and password, then runs the authentication modules. The remaining arguments are passed along as arguments to modules. modules is one or more authentication modules (see the authlib(7)[1] manual page). Each authentication modules runs the program specified by its first argument, allowing the authentication modules to be chained. The last program in the chain is courierpop3d , which provides the actual POP3 service. In accordance with the authentication protocol, as described in authlib(7)[1] courierpop3d reads file descriptor 3 to see if the userid/password has been succesfully validated. If not, courierpop3d terminates. Otherwise, courierpop3d expects to be already running under the appropriate user and group id, with its current directory set to the account's home directory. The first order of business is to find the account's Maildir. If the environment variable MAILDIR is set, that's where we go. That should be the pathname to the account's Maildir. The environment variable MAILDIR may be set by the authentication module. If MAILDIR is not set, courierpop3d uses its first argument. Usually, the default maildir is $HOME/Maildir, therefore the first argument to courierpop3d is "./Maildir". SEE ALSO

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 SEE ALSO
