[otrs] Ticket escalation on reciept of email

I was wondering if anyone out there know if this was possible. Is it possible to have a ticket go to an escalated state if an external email was posted to the ticket by the customer? I'd rather not have the time to reply (update escalation time for the sla or queue) be changed, but just have it be the fact that an email was received be the cause of escalation. Any ideas?
