I am running a server at a very small company (5 users typically). However, since I have some forwarding of a shared mailbox, and cad files are sent around, I can see some decent throughput on a day (50 megs is not atypical).
However, I saw 400 megs the other day, none of which was marked as spam by the graph. I don't see where any of the users could have sent anything resembling that size.
Is there a way to see the messages sent in a time period (one day, one week, etc), and maybe sender, recipient, and size? I am slightly concerned about my mta being used by spammers, but I'd also like to see where all this is coming from.
Thanks for everyone's always kind help on this wonderful product.
