out-of-office auto-reply reopens a support ticket that has been closed

We utilize the notification rule to "Acknowledge Contact when the request is closed."  However, when a Contact is out of the office, their out-of-office auto response reopens the ticket.

Is there a way to turn off the functionality where a Contact is able to reopen a ticket by replying to the email? In general, we would like to make it so that a reply does NOT reopen the ticket.

Thanks!
