pop3d - POP3 server process


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


Pop3d is a POP3 server. It accepts commands on its standard input and responds on its standard output. It MUST 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
  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.
