Hello,

I sent a message to customer support about the problem facing since two days but no reply received so far. The problem is being frequent now and posting that message again here for quick response.

Since few days some emails received and forwarded from our gmail account to zoho support isn't being delivered. It is showing error as Mailbox delivery failure policy error at zoho support. I have attached two screenshots of this error as showing in gmail. Please look into this matter and resolve as soon as possible. 

Looking forward your reply. 

Thank you.
