Does Yahoo mail do things differently?

[Sanjit]

Hi everybody,
I have currently setup a zimbra mail server.My mail server can send and receive to most other mail servers, e.g., gmail.com. But users at Yahoo get the following error when they try to send to us:

**********************************

Message from yahoo.com.
Unable to deliver message to the following address(es).

<test@mydomain.com>:
Sorry, I couldn't find a mail exchanger or IP address. (#5.4.4)

I am new to setup mail server. CAN ANYBODY HELP ME OUT. Thanks in advance.

Can you please post the result of the following commands?

> dig yourdomain.com MX

try this pointing to your ISP dns server also (need to check your MX is configured correctly)

mail.angulonline.com is not resolving to any IP, please check and correct it in the DNS

For that domain I get different NS records aswell

;; AUTHORITY SECTION:
angulonline.com.	86400	IN	NS	ns2.vndv.com.
angulonline.com.	86400	IN	NS	ns1.vndv.com.
