× Few antiviral products inadequately detect 3proxy as Trojan.Daemonize, Backdoor.Daemonize, etc and many detect 3proxy as a PUA (potentially unwanted program). It may cause browser warning on download page. 3proxy is not trojan or backdoor and contains no functionality except described in documentation. Clear explanation of this fact is given, for example, in Microsoft's article.

NAME

smtpp − SMTP proxy gateway service

SYNOPSIS

smtpp [-d] [-l[[@]logfile]] [-pport] [-iinternal_ip] [-eexternal_ip] [-hdefault_ip[:port]]

DESCRIPTION

smtpp is SMTP gateway service to allow internal users to access external SMTP 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 25.

-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 SMTP authentication support. Set client to use internal_ip and port as a SMTP server. Address of real SMTP server must be configured as a part of SMTP username. Format for username is username@server, where server is address of SMTP server and username is user´s login on this SMTP server. Login itself may contain ´@´ sign. Only cleartext authentication is supported, because challenge-response authentication (CRAM-MD5, SPA, etc) requires challenge from server before we know which server to connect.
