Getting 553 error while sending emails from zoho web client

Getting 553 error while sending emails from zoho web client

Hi Team,

I am getting " Unable to send message;Reason:553 Relaying disallowed. Invalid Domain - shiv@myearth.id" error when I am trying to send emails from my shiv@myearth.id account. I am using the web client for zoho, so not sure what to do here.

Thanks,
Shiv
