Is it okay to have two dns servers (both are currently working) listed in the smtp settings? We currently list both dns that was provided to us by our T1 provider. Our cpu usage is usually around 100% during the normal work hours and around 24%-50% during off hours, but everything seems normal? Is this normal, any thoughts? Thanks.
