[Cialug] SMTP Proxy

[Josh More]

Drifting off topic...

It's probably broken in most distros because you can do the same with netcat (nc on some distros), so redir may not be well maintained.

You can do all sorts of wacky fun with netcat.

For simple redirection like this I use a tiny little program called redir that will allow you to listen on a TCP port and connect to another ip on another port. I would compile it by hand because I have found it to be broken on most distributions.
