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
          }
