smtpp - SMTP proxy gateway service
smtpp [-d] [-l[[@]logfile]] [-pport] [-iinternal_ip] [-eexternal_ip] [-hdefault_ip[:port]]
smtpp is SMTP gateway service to allow internal users to access external SMTP servers.
-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. |
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.
