e-g I have two domains registered with GoDaddy
1. 1st.com2. 2nd.com
1st.com domain is attached with GoDaddy and hosted with GoDaddy also
2nd.com domain is attached with GoDaddy but hosted with other providor
I have changed the Nameservers of 2nd.com towards other provider.
My Problem is:When any user of 1st.com sends email to any user of 2nd.com, it goes to nowhere, but vice versa is working fine
Please note that 2nd.com is receiving emails from whole world properly
In short, 2nd.com is not receiving emails from 1st.com only.
