NAME

pop3p - POP3 proxy gateway service

SYNOPSIS

pop3p [-d] [-l [[@]logfile]] [-p port] [-i internal_ip] [-e external_ip] [-h default_ip[:port]]

DESCRIPTION

pop3p is POP3 gateway service to allow internal users to access external POP3 servers.

OPTIONS

| |

-I

| |

Inetd mode. Standalone service only.

| | |

-d

| |

Daemonize. Detach service from console and run in the background.

| | |

-t

| |

Be silenT. Do not log start/stop/accept error records.

| | |

-u

| |

Never look for username authentication.

| | |

-e

| |

External address. IP address of the interface the proxy should initiate connections from. By default, the system will decide which address to use in accordance with the routing table.

| | |

-i

| |

Internal address. IP address the proxy accepts connections to. By default, connections to any interface are accepted. It´s usually unsafe.

| | |

-p

| |

Port. Port proxy listens for incoming connections. Default is 110.

| | |

-h

| |

Default destination. It’s used if the target address is not specified by the user.

| | |

-l

| |

Log. By default logging is to stdout. If logfile is specified logging is to file. Under Unix, if ´@´ precedes logfile, syslog is used for logging.

| | |

-S

| |

Increase or decrease stack size. You may want to try something like -S8192 if you experience 3proxy crashes.

CLIENTS

You can use any MUA (Mail User Agent) with POP3 support. Set the client to use internal_ip and port as a POP3 server. The address of the real POP3 server must be configured as a part of the POP3 username. The format for the username is username @ server, where server is the address of the POP3 server and username is the user´s login on this POP3 server. The login itself may contain an ´@´ sign. Only cleartext authentication is supported, because challenge-response authentication (APOP, CRAM-MD5, etc.) requires a challenge from the server before we know which server to connect to.
