NAME

       pop3d - POP3 server process

SYNOPSIS

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

DESCRIPTION

       Pop3d  is  a  POP3  server.  It accepts commands on its standard input and responds on its
       standard output.  It MUST invoked by cyrmaster(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
              Read configuration options from config-file.

       -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.
