Dear all,

In our office we are running zimbra OSS 7.1.1 with ubuntu 10.04 64 bit server with the domain Our server is running behind the firewall using slit DNS running on the same server. Now our company has registered a new domain called

I added this in our existing mail server using the admin console. Now I can able to send mails to outside domains. But I can't receive from those domains.

I added the correct MX and A record to point our public IP in the control panel of our domain provider. What else is missing in my configurations.

Do I have to add A and MX record to the new domain in split DNS configuration. If so please tell me how?
