NAME    [Toc]    [Back]

       pop3d - POP3 server

SYNOPSIS    [Toc]    [Back]

       /usr/sbin/pop3d [-d] [-s] [-t trace-file] [-T timeout]

OPTIONS    [Toc]    [Back]

       Sets  the socket to debugging and turns on debugging.  All
       debugging information is saved using  syslogd.   Turns  on
       statistics  logging  using  syslogd(8). At the end of each
       pop3d session, the following information is logged:  username,
 number of messages deleted, number of bytes deleted,
       number of message left on server, number of bytes left  on
       server.   Turns  on debugging and saves the trace information
 in trace-file using the fprintf(3) command.  When the
       server is waiting for a command to arrive from the client,
       it times out after the specified  number  of  seconds  and
       terminates  the  session.   This  avoids having pop3d processes
 hang forever waiting for command input from clients
       which have terminated abnormally. A small value is acceptable
 for small to medium networks where the network  delay
       is  within  a  few seconds.  In this case 15-30 seconds is
       not unreasonable.  Networks with large delays  in  sending
       packets  (for  example,  SLIP  links) may require a larger
       value.  In this case 300 seconds (5 minutes) is not unreasonable.

DESCRIPTION    [Toc]    [Back]

       The  pop3d  server is an implementation of the Post Office
       Protocol Version 3 from Qualcomm,  Incorporated.  It  provides
  remote  users with the ability to manage electronic
       mail on a UNIX system.

   Authentication    [Toc]    [Back]
       The operating  system  supports  the  following  types  of
       authentication  for  the pop3d server: UNIX authentication
       using the /etc/passwd file, Authenticated POP (APOP),  and
       enhanced  security using C2. The default is UNIX authentication.

       To enable APOP authentication for a user, you must add the
       user  to  the  mailauth  database. See mailauth(8) and the
       Network Administration: Services manual for more  information.

       To  use  C2 secure authentication, you must configure your
       system to use C2 security. See secconfig(8) and the  Security
 guide for more information.

   Logging    [Toc]    [Back]
       The  pop3d  server uses the syslog daemon to keep a record
       of  its  activities.    Messages   are   logged   in   the
       /var/adm/syslog.dated/date/mail.log file.

   Debugging    [Toc]    [Back]
       The  pop3d program will log debugging information when the
       -d parameter is specified  after  its  invocation  in  the
       inetd.conf  file.   Care should be exercised in using this
       option since  it  generates  considerable  output  in  the
       mail.log  file.   Alternatively,  the  -t file-name option
       will place debugging information into file file-name using
       fprintf instead of syslog.

       You  can confirm that the POP server is running by opening
       a telnet session to  port  110.   For  example:  %  telnet
       myhost 110 Connected to myhost.berkeley.edu.  Escape character
 is '^]'.  +OK UCB Pop server (version 1.6) at myhost
       starting.   quit  +OK  Pop  server  at myhost.berkeley.edu
       signing off.  Connection closed by foreign host.

   Extensions    [Toc]    [Back]
       The server implements two extended commands: XTND XMIT

              Sends  a  mail  message  using  /usr/sbin/sendmail.
              XTND XLIST header [num]

              Extracts  and returns the specified header line for
              the specified message number. If the num  parameter
              is missing, the command returns the header line for
              all the messages that are not currently marked  for

RESTRICTIONS    [Toc]    [Back]

       Note  that  this  implementation of Qualcomm's POP3 server
       does not support Server Mode, Kerberos authentication,  or
       the bulletin feature.
