How can we avoid multiple tickets being created for hourly server alerts sent to support@****.samanage.com?

Our server alerts send an email to support@****.samanage.com, creating a ticket each time. The problem is that once there is an issue with a server, it tries every hour to run the job. This leads to a ticket being opened every hour until the issue is resolved on the server. Is there a way to have subsequent alerts automatically attach to the original ticket rather that create a new one?
