What results is a nightmare of tickets being opened on each support system automatically back and fourth in a loop forever until someone intervenes.

How it happens is that we send a response "your ticket has been created" that response goes to the other companys support system and they respond "Thanks fro the email your ticket has been created" and then our ticket opens a new ticket based on that email saying "your ticket has been opened" and so on and so on and so on.

When this happens is there a way within zoho to flag the email address and reject new tickets from it temporarily?  Currently we have to go into our email system and block it manually, which suck if the mail admin is not around when this happens.
