Dear all,

I am experiencing problems to use one of my email accounts with Zoho as sign up and contact form point on my website (built with Wordpress).

My email shows the following error message:

5.4.4 DNS error:NXDOMAIN. Domain not found :firewlk.com

I have 5 email address in total with Zoho but only one is working to send/receive messages from my webpage. 

Can someone please assist?

Thanks,

Alex
