How to calculate user mail

[prizes]

Hello everyone.
How to calculate which user has sent the most emails?
zmdailyreport shows only summary data, so it is not clear who sends more.
The problem is that many services (like Gmail) think my Zimbra server is sending spam.
But how do you understand what is generating this spam?

Actually zmdailyreport shows statistics by user. I just didn’t look closely.
