How to view total number of emails sent?



I would like to find out how many total emails that was sent from a specific email address that’s hosten on our MIAB server, where would I find this?

I’ve looked in mail.log and there’s so much data that’s unreadable, I was wondering if there was any other log file location that offered the statistics that I need?



Login as the user, and count the emails? There is a command line tool that can do this, though I forget the name of it.
