pop3proxyd — Cyrus IMAP documentation

This is a hard linked copy of pop3d(8), retained for backwards compatibility from when a murder frontend used its own pop3d binaries.

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

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.

-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.

-H

Tell httpd to expect a HAProxy protocol header from the sender.

-s

Serve POP3 over SSL (pop3s).  All data to and from pop3d is encrypted using the Secure Sockets Layer.

-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.

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
}
