I have a group of mail servers, one of which has the IMC.

This server is about to be replaced. The new server has taken over most of the folders etc, but does not receive mail, only sends.

I tried stopping the Internet Mail Service on the oldserver, and then telneting to the server, this failed. Internaly, they both accept telnet on port25.

Some details to help you, help me.

2 server, ex5.5, sp4 (nt sp6a)
both use DNS to route mail.

Both are on the local side of MS Proxy 2
Using telnet externally, will only connect to mail.domain.com, but not to email.domain.com

Just check u r mx record ,
also u have'nt mentioned the difference
between mail.domain.com & email.domain.com ,

I have a feeling its some thing to do with the mx record for that domain.

Hope this helps
Thanks

Mail, and email are the 2 server host names., for the arguement, they are set up internally as email.domain.com, and mail.domain.com.
Proxy can see both hosts. mx is setup like this, each domain we have has the mx set to mail.domain.com, I have 1spare dom name that has had the mx changed to email.domain.com.

domain.com has both email and mail setup as "cname" and both point to the IP of our Proxy.

If I try and telnet internally, I can get to port 25 on both, but externally, only to the original server. Is there anything in proxy to configure?

You need to have a wspcfg.ini on the new exchange server. I would copy the existing one from the old server to the new.

this is already done and working, like I said it sends mail ok, just doesnt recieve any.

You need to tell the Proxy Server where to send the mail. Proxy Server works by mapping the outside port number to a particular IP address and port number inside so you need to change this mapping. Unfortunately, I can't tell you exactly how to dothis because I don't have a Proxy Server in front of me and I'm not that familiar with it.

But if you look in the Help facility for port mapping, you should find the right info.

This is the situation that is occuring.

The wspcfg.ini on the origional Exchange server is having the proxy server listen on port 25 for incoming traffic. All traffic on port 25 is routed to the first server. The wspcfg.ini on the new server istrying to do the same, but is being blocked by the first.

Remove the wspcfg.ini from the old server and then telnet to the new one(with a wspcfg.ini file in place).

so your saying that I can not have 2 email servers connected via the proxy ?

If no-one can say any different, Ill give you the points as it seems to be whats going on.

so reply anyway, even just to say "yes", then I can award you the points.

thanks

You can have multiple exchange servers behind a proxy server, but only one of them can have the IMC connector.

I have 2 with an IMC, both send mail, but as you already said, the port is bound by the wspclient
