Email forwarding

I have my email from Zoho forwarded to my gmail account. Lately gmail is sending me messages that they couldn't forward certain emails (mail forward failure) because their system has detected an unusual rate of unsolicited mail originating from my IP address. To protect their users from spam, mail sent from my IP address has been temporarily rate limited.
I come to zoho mail, but those messages are not in my inbox or any other folder. Why there's not record in zoho of those emails?
Thanks
Sandra
