Port Forwarding

someone pointed me to a program called Relay TCP. This program allows you to "relay" one port to another. I have been trying to get this to work with smtp email. I keep getting an error message in the wg log. I am running the service on the same box as wg, and I am able to do a telenet to port 25 of the domain and it "forwards" to 225. Does anyone know why the mail won't get through?

What's the error message?

If I put the smarthost name in, the message SMTP SEND FAILED - (Dial) Failed to connect to xx.xx.xx.xx
Without a smarthost name, it appears to just do nothing

does your isp mail server require authentication?
i know on my dsl i have to login to my smtp to send.
comcast you dont.
could be getting bounced back before it even gets sent to ya.
also some other isp's block 25 for incoming to prevent spam abuse.

If I use bellsouth, my isp with mail.bellsouth.net, it needs authentication and you have to use
xxxxx@bellsouth.net. I subscribed to a service at DNSEXIT.COM that relays mail and accepts on 2525 and 26. Also, they do not require authentication, they will open up to your IP without authentication.
It would seem as though I could leave the smarthost blank and run Relay TCP as a service and forward to 2525. I am using it like this
Route from local port 2525 to RELAY.DNSEXIT.COM 2525

Mail was sucessfully received and believe it or not sent. The only issue, is it seems to only send mail when the server is re-started. still scratching my head over this one

RelayTCP. Its a great program, able to telnet to the remote email server with it. I did find another solution. Routing the mail to another win 2k server on my lan, and havving that server puh it out on port 2525 to dnsexit. I am quite impressed with DNSEXIT, they have great tech support and reasonable prices. They are sending me mail on port 26 and accepting on port 2525. Plus they are "whitelisted"

On inbound I believe it just listens on the port and receives as mail is waiting

Actually, on mine mail is sent as soon as a user hits "enter" to send the mail; and it listens on the port and receives any mail as it comes in.
