[SOLVED] MTA Relay

[emcampos]

Fellows;


We have an existing mail server. This is our primary. Then we set up Zimbra as second mail server.

Both server's IP are private and are matched to their corresponding public IPs.

The problem is i cant force the Zimbra (mail2.xxxxxxx.net) to not use MTA Relay (Relay MTA for external delivery: mail.xxxxxxx.net port:25).

If i disable this or leave it blank this is what happens;

1) Acounts made by second server can not send mails to the accounts made from the primary server but can receive mails from it. (POP3 ok but SMTP is not ok)

2) I can receive and send mails to Yahoo Mail.

Our concern is that it seems like our Zimbra box is dependent on the primary server (Mdaemon on Windows Server) for its outgoing mail traffic.

What we wanted is that Zimbra must not rely on the primary server so that even if it bogs down, Zimbra can still function.

HOW CAN I FORCE ZIMBRA TO BE INDEPENDENT?

When i leave MTA blank, i cant send mails to the primary server anymore.

What happens ? Also, would you please post what version you are using

su - zimbra
zmcontrol -v

zimbra@mail2:/home/boss$ zmcontrol -v


Release 5.0.12_GA_2789.UBUNTU8 UBUNTU8 FOSS edition

=============================================


When I installed Ubuntu, i only activated SSH for SSL connection (putty).

Then I configured the IP address. These are local IP addresses. These are bonded to public IP addresses. Both are served by the same DNS (ISP's DNS). Both public ip for the 2 mail servers have an MX and A records already. We also have a local DNS and the IP address bonded to the hostnames for the 2 servers are local IP addresses. Both MX and A record were added.

After this, I installed Zimbra. No other configurations done except putting the FQDN of the primary server into the Relay MTA and the email accounts.

Once, i remove this MTA Relay, it cannot send mail to the primary server anymore.

By the way, here is the error message in the log file;

mail server 2 (Zimbra) = 192.168.1.253

local DNS (2 int) = 192.168.1.3 172.16.10.3

So what does happen when you set the relay to blank ? Did you restart ZCS once you made that change ?

Please update your forum profile with that information.

Who set-up the MDaemon server as the relay (and how did they do it) or is this actually a Split Domain set-up? If it's a Split Domain set-up then just reverse the changes that were made to your server.

[emcampos]

The Mdaemon server was already there when i got in. It's handling 500 users and we are out of slots. We are now trying to find a backup server. If this backup server performs well, we will replace the old server with it.

I already installed a SquirrelMail on UBUNTU for this second server and I HAD NO HASSLE INSTALLING IT.

I had no problems at all. It worked fine. It can communicate with the old server without any problem.

But we decided to try Zimbra.

Zimbra is feature-rich. It's pretty neat.

But configuring it is a headache when the setup is complicated.

I dont know if the old server was configured to be a relay MTA but since the Zimbra worked when i put its FQDN in the Relay MTA field, then it must have been configured to be as such.

But I was able to put up SquirrelMail without any hassle, then why this with Zimbra now?

Please help.

If you wish to run a Zimbra server in the same domain as your MDaemon server then you'll need to set-up a Split Domain system, read the article in the link I've given you in my post above.

but we want to make it fully independent from the first server. is this not possible?

we were able to do that on SquirrelMail. No hassle in installing.

[phoenix]

You can run it with a different domain name on the Zimbra server, if you want to have the Zimbra server in the same domain as your other mail server then you'll need a Split Domain set-up.

Squirrelmail is a web front-end for a mail server isn't it? That's not what Zimbra is, it's a full mail server and collaboration suite - you're not comparing like with like.

What, exactly, is it that you're trying to achieve by using Zimbra?
