Send mail is OK, but can not receive any email for a week

Send mail is OK, but can not receive any email for a week

I'm a zoho customer for 3 years and my email account -  frankz@newlandmagazine.com.au

I've been using mail.zoho.com simply by inputting username and password to send and receive email from 2013 and no configurations have ever been changed since then. but strangely, sending email from my account works fine...so I guess it's not my problem?

From last week I can not receive any email and the following error came up -

mx.google.com rejected your message to the following email addresses:

frankz (frankz@newlandmagazine.com.au)
The address you sent your message to wasn't found at the destination domain. It might be misspelled or it might not exist. Try to fix the problem by doing one or more of the following:

  1. Send the message again, but before you do, delete and retype the address. If your email program automatically suggests an address to use, don't select it.
  2. Clear the recipient AutoComplete cache in your email program by following the steps in this article: Status code 5.1.1. Then resend the message, but before you do, be sure to delete and retype the address.
  3. Contact the recipient by some other means (by phone, for example) to confirm you're using the right address. Ask them if they've set up an email forwarding rule that could be forwarding your message to an incorrect address.
