[otrs] Send agent notification when customer sends an email to a queue

Hi all, Our system is queued based on customer names. So any @xyz.com would go to a XYZ queue, and so on. Currently we need OTRS to email a group of agents when the customer updates the queue. We have a notification event that would do so, but the problem is that it emails the whole team even when an agent updates a ticket. Any ideas? Thanks //M
