My Incoming mail got blocked

My Incoming mail got blocked

Hi,

 Yesterday evening I got an email with the subject.
 
 "Zoho MAIL ADMIN :: Your mail incoming is blocked"

 The body of the message said: "Incoming mail rate exceeds limit"

  Now no email are coming in.

  I only receive a few emails a day. Can you please check and see how we can fix this.

  Thanks.
