Hi,
I am new to mail server.I need to see something like how much traffic is being used by e-mail, who sends and receives most messages, where it was sent, how often local pc is contacting server (hits), which one most, how many data are sent to particular user and globally to all local pcs, how many data are received,
when server is down, not responding, responding slow, I/O, etc
We are using NPM monitoring tool. Any suggestion, how to configure this.
