NAME

pop3p - POP3 proxy gateway service

SYNOPSIS

pop3p [-d] [-l[[@]logfile]] [-pport] [-iinternal_ip] [-eexternal_ip] [-hdefault_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

Daemonise. 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 interface proxy should initiate connections from. By default system will deside which address to use in accordance with routing table.

-i

Internal address. IP address proxy accepts connections to. By default connection to any interface is accepted. It´s usually unsafe.

-p

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

-h

Default destination. It's used if targed address is not specified by user.

-l

Log. By default logging is to stdout. If logfile is specified logging is to file. Under Unix, if ´@´ preceeds 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 client to use internal_ip and port as a POP3 server. Address of real POP3 server must be configured as a part of POP3 username. Format for username is username@server, where server is address of POP3 server and username is user´s login on this POP3 server. Login itself may contain ´@´ sign. Only cleartext authentication is supported, because challenge-response authentication (APOP, CRAM-MD5, etc) requires challenge from server before we know which server to connect.
