SMTP Traffic report bug or security flaw

divisionx

New Pleskian
For all domains that have Email forwarding, Report->Traffic shows SMTP traffic at 100% even though in many cases there is no SMTP traffic at all. These domains have empty statistics folders so I do not know where Plesk is getting the SMTP traffic data from. Even if I set all the limits to unlimited the SMTP traffic is still shown as 100%. Is this a bug or is someone using our server to send spam using a flaw in these types of account?

Plesk 7.5.3. on Fedora 1

Any help greatly appreciated.
 
I do not understand. Are you concerned that all traffic is from SMTP and there is no traffic from HTTP?
