Sendmail Multiple server configuration

[wichoe]

I'm new with sendmail and I have to configure 3 servers for the same domain and as you can guess I have no idea how to do that.

I have one server already runing this one it's main server, what I need to do it's to configure the other two servers so they can get the mail from first server, this servers are in two different offices, connected by a private line. How can I do it?

Please help me

You have confused the daylights out of me. Why do you need 3 mail servers for the same domain? You said that the machines in the other offices are connected via private line. Does this mean they are not on your network and use ppp to connect to your mail server? Let us know what your goal is and how your net is setup so we can do a better job of helping you get there.

My main mail server it's a cobalt cube, the DNS daemon it's running, and yes, the other offices are in my lan.

This it's what I think I should do, correct me if I'm wrong: because the main server it's already getting the mail for everybody, I need to configure the two servers for each office so they get/send the mail from/to the main server for people of each office.

Thanks for the help.

I don't understand why you want to have servers in each office. Can't you just use a POP3 server then they can get their mail off the main server just as they would from their ISP?

You're right I could use just one server.

We're connected to the other offices by a private line, we use the connection to run oracle applications(client-server by the way) so I don't want to put more traffic than it should, that's the main reason.

That is where you are losing me. I don't know what you mean by "private line". To me, a private line is a phone line in an office that can receive and make calls to the outside world without going through the switch (PBX). If I knew how your offices are networked, I would be able to give you more details on how you can accomplish your goals.

Every branch office has this private line or a dedicated telephone line, in each side of the line we have a router, which make every office part of the LAN, nothing fancy there. If it helps forget about the line, let say I need a server for each division, I have one main server which gets all the mail, the division's server will get the mail from the main server and each division member will get the mail from this secondary server.
