I have setup a server just for email. I want to move all email accounts off my web servers onto this one. This is because spam/virus scanning was using a lot of CPU/RAM which slowed the server and so websites down. Not good! So email on another server will make the websites run faster more often.
So I would like to start to move the highest email users first… so those with the most email coming in and going out, as they would be scanned the most. OR the ones using highest CPU/RAM.
I wondered how one could check this, any ideas? So the user with the most email usage.
