OK, here is my problems and I hope someone has an idea because I have tried everything I can think of. I am in the process of switching from a Windows 2k server to a Linux serv. With Windows everything worked like it should(www,mail,ftp). I have the new Linux server setup. I have security in place with exceptions for the standard services. I have www working fine. The problem is with sendmail. I cannot get it to accept connections even though sendmail says it is "accepting connections". I am using IP chains and I have added a rule to accept all connections for smtp. Still when I try to send a simple message from a different Linux machine using send mail I get "Connecting to mail.doctor-raid.net. via esmtp..."
"Deffered: Connection refused by mail.doctor-raid.net"

Any suggestions would be appreciated!!!
Thanks.

P.S. I am using Redhat 7.1
Sendmail 8.11.3(?)

Hmm...ok..so no one has any ideas about my problems with sendmail. I will ask a different question. There has to be someone around that has a Linux machine acting as an Internet mail server. Can you tell me what you are using and how hard it was to setup? I'm not really a newbie I just haven't setup mail on Linux before. Yes, I have a decent internet connection(Cable Modem) and I have a registered domain. As I said in the first post, I have had everything working fine for over a year on a Win2K server and I already have Apache working on the Linux server. I just REALLY need to get mail working so all the messages I have coming to my domain dont keep bouncing. I have tried sendmail,qmail,and CommuniGate. But have not been able to receive mail with any of them. Any suggestions would be greatly appreciated.

Are you absolutely sure that your firewall is allowing port 25 connections? Go to another machine and type
What do you get?

It seems to be accepting connections on port 25. I actually have a server called CommuniGate Pro running right now. Its not really what I wanted but I am desperate. When I telnet to the machine I get a message something like:

220 <hostname> ESMTP CommuniGate Pro 3.4.5


I know this is where you would enter SMTP commands but I don't know any.

Any other ideas?

Check /etc/sendmail.cf for the following entry

O DaemonPortOptions=Port=smtp,Addr=127.0.0.1, Name=MTA

And change to

O DaemonPortOptions=Port=smtp,Addr=0.0.0.0, Name=MTA

This will sort out your problem. The original config causes sendmail to only "listen" to port 25 on localhost loopback(127.0.0.1). Changing the config to 0.0.0.0 means that all interfaces will be used.

Cheers

My sendmail relays fine without the above option. I've just got my domain setup in /etc/mail/relay-domains and have added an extra Cw line to sendmail.cf so it knows it is the mail server for that domain.

How have others done it?

You ppl should try Postfix... very nice smtp mail server
And easy to set up..

http://www.postfix.org

From my experience with Sendmail if I were running it as anythings more than an experiement I would either spend a very long time reading up on it or use another relay agent. There seem to be some nice ones out there. While Sendmail appears to be the ultimate in flexibility this can lead to serious problems if you don't understand it all.

I've heard that qmail if supposed to be good too. Probably a mission for the future.
