Incoming SMTP Mail through MS Proxy Server

I have a Domino 5.02a Server on a Windows NT MAchine which is behind an MS Proxy Server on another machine. The Proxy Server is the only visible IP Address (Internal Addresses are private). I have managed to set up Outgoing SMTP mail using the HTTP Tunneling Protocol and this works OK, but I have been unable to set up Incoming SMTP Mail from the Internet to the Domino Server.

Any advice?

Hello dmpdmpdmp,

U can obtain ur objective by specifying ur internal ip address of the domino server in the MS proxy server's inbound settings for mail forwarding.

So that whenever ur proxy will receive any mail from the intenet on port 25, it will forward it to the domino server because of the inbounf mail forwarding option.

Hope this will help u.

Cheers

Yes, that seems logical, but where do I actually do that? The only way I could get outgoing SMTP Working was to use the HTTP Tunneling Proxy, is there anywhere I can set up an incoming connection through the same proxy - a registry setting perhaps?

Regards,
Dave.

Hello Dave,

In your MS proxy goto the security tabed page and enable the packet filtering option and add SMTP. Click on the "Custom filter" and put TCP,Both Fixed Port - 25. Select the Interal Computer and put the internal IP address of the Domino server.

This process will forward all ur inbound trafic to the internal computer which u hae specified.

Hope this makes sense to u.

Thanx

It would appear that you have to enable the Packet Filter as you have described, but also that you have to have the WinSock proxy client running with the wspcfg.ini file installed in the Domino Directory. If anyone else wants to try this setup the wspcfg.ini file looks like this:

[Common Configuration]
ServerBindTCPPorts=25
Persistent=1
KillOldSession=0

With this setup I was able to get Incoming SMTP Mail to work.

It seems to be very difficult to get a complete set of instructions for this, so thanks to you for your help and thank goodness for Experts Exchange!

Regards,
Dave Pearson
