Sending mails to domains without use of DNS server

[generic31]

Hi,
I have set up a mail server using the zcs-4.0.1_GA (Open Source) version on a RHEL 4 box with 1GB RAM.
Initially, I did encounter some problems but that was solved by searching the forums. Now the setup is running perfectly and I can send and receive mails from the Internet without any issues.

The domain for which the Zimbra Server was setup is first.site.com.

There are two other domains namely 'site.com' and 'second.site.com' which are handled by other administrators and running separate mail servers(not Zimbra).

I am responsible for the 'first.site.com' domain only.

Now, I wish to send mails to the two 'local' domains namely site.com and second.site.com directly to a mail server with IP address 172.31.1.1 without using any DNS servers for these two domains.

Is there some way by which I can specify Zimbra to send the mails to 172.31.1.1 for the above two domains only, whereas performing regular DNS lookups for all the other domains?

I tried to search the forums but could not find a solution to the problem. Any help would be appreciated.

Thanks in advance.

Just specify how u solved it

ikmsupport, I configured it as follows:

suppose the name of the domain to which the mails are to be sent directly is domain.com.

Do the following:

su - zimbra
zmprov cd domain.com
zmprov
On typing zmprov, you will get the zmprov prompt.(zmprov>) Continue with the following commands:

zmprov> md domain.com zimbraMailCatchAllAddress @domain.com
zmprov> md domain.com zimbraMailCatchAllForwardingAddress @domain.com
zmprov> md domain.com zimbraMailTransport smtp:192.168.0.1
zmprov> exit

postfix reload


Note: Simply replace '192.168.0.1' with the address of Mail Server of 'domain.com'.

That should do it

Hi,

The provided commands really worked except when I need to send a message to an address like user@lists.domain.com.

I have tried creating a new domain as lists.domain.com with the same commands, but then, every message to user@lists.domain.com gets into the queue as a message to user@domain.com, which is not the correct address.

Is there a solution to that ?

Regards.

This thread is almost five years old and a completely different, and older, version of Zimbra. You really shouldn't be using a catch-all address in Zimbra, it's an open invitation to spammers. In future, start a new thread with your specific question and list the installed version of Zimbra that you're using and give a full explanation of what you're trying to achieve and why.
