cpanel view mail statistics
upon viewing the mail statistics in WHM i see this:Top 50 local senders by message count
-------------------------------------
1170 7284KB mailnull
1070 42MB user1
679 1446MB user2
671 24MB user3
570 12MB user4
is this an indication that user 2 is basically smoking the server either sending or receiving emails?
customer says he sends a handful of emails per day and receives hundreds of spams.
please advise on what more i can do to verify this, thank you
