NAME

pop3d - Cyrus IMAP documentation

POP3 server process

SYNOPSIS

pop3d [ -C config-file ] [ -U uses ] [ -T timeout ] [ -D ] [ -s ] [ -k ] [ -p ssf ]

DESCRIPTION

pop3d is an POP3 server. It accepts commands on its standard input and responds on its standard output. It MUST be invoked by master(8) with those descriptors attached to a remote client connection.

pop3d reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C .

If the directory log / user exists under the directory specified in the configdirectory configuration option, then pop3d will create protocol telemetry logs for sessions authenticating as user .

The telemetry logs will be stored in the log / user directory with a filename of the pop3d process-id.

OPTIONS

-C config-file

Use the specified configuration file config-file rather than the default imapd.conf(5) .

-U uses

The maximum number of times that the process should be used for new connections before shutting down. The default is 250.

-T timeout

The number of seconds that the process will wait for a new connection before shutting down. Note that a value of 0 (zero) will disable the timeout. The default is 60.

	-D		Run external debugger specified in debug_command.
	-s		Serve POP3 over SSL (pop3s). All data to and from pop3d is encrypted using the Secure Sockets Layer.
	-k		Serve MIT's KPOP (Kerberized POP) protocol instead.
	-p ssf		Tell pop3d that an external layer exists. An SSF (security strength factor) of 1 means an integrity protection layer exists. Any higher SSF implies some form of privacy protection.

EXAMPLES

pop3d is commonly included in the SERVICES section of cyrus.conf(5) like so:

SERVICES {
    imap        cmd="imapd -U 30" listen="imap" prefork=0
    imaps       cmd="imapd -s -U 30" listen="imaps" prefork=0 maxchild=100
    pop3        cmd="pop3d -U 30" listen="pop3" prefork=0
    pop3s       cmd="pop3d -s -U 30" listen="pop3s" prefork=0 maxchild=100
    lmtpunix    cmd="lmtpd" listen="/var/run/cyrus/socket/lmtp" prefork=0 maxchild=20
    sieve       cmd="timsieved" listen="sieve" prefork=0
    notify      cmd="notifyd" listen="/var/run/cyrus/socket/notify" proto="udp" prefork=1
    httpd       cmd="httpd" listen=8080 prefork=1 maxchild=20
}
