SMTP Authentication of your mail client

SMTP Authentication of your mail client

I had setup my custom domain( ignitedmindsluminaries.com ) with zoho mail and created a mail account associated with it. While i am able to send mails to other email ids. I cant receive mails. I tried to send a mail from my another id( ganesh@siddhisoftwares.net) and its failed.

The error i have received is:

The error that the other server returned was:
550-Please turn on SMTP Authentication in your mail client.
550-mail-ob0-f173.google.com [209.85.214.173]:35349 is not permitted to relay
550 through this server without authentication.

Please let me know what is missing.

Regargs,
Ganesh
