We'd like to have it where if someone emails in a support request, if the request is outside of normal business hours, a notification gets sent out to the support group via email. 

Right now every email that gets sent to our support email address not only goes into SCP, but also emailed to every support rep. We'd like to cut this out to only occur after hours (as not every rep is logged into SCP every moment they are at home). 

Anyone have any suggestions or is this an available feature in SCP? I've looked at the business rules now, but don't see any criteria available to pick created time.
