Address not fund

Address not fund

Dear all,

Please, I created my Zoho Email Account and I am able to send messages to other email address. But I can not receive any email to my inbox. The senders got this message:

Your message wasn't delivered to (my Zoho email)  because the address couldn't be found, or is unable to receive mail.

Please, can you help me solve this, I will be very grateful.

Thank you in advance.
