since 2 months we started to observer following issues , current PLESK version is 7.5.2 , RedHat ES3.0, still issues remains

1 - Client and Domain Usage Overage Notification emails stoped , we dont receie them any more...
we can receive other notification emails (i.e client creation , domain creation...etc)
2 - Client Bandwidth Usage is allways displayed 0 when clicked on Clients>traffic History
3 - hen logged as administrator i can see i.e Nov , Dec , Jan , Feb traffic history for a client but when logged as client we can only see Nov and Dec , for the same domain?
4- Also the Bandwidthds totals differs when logged as administrator i see 5987MB Bandwidth usage for the domain,
when logged as the client i see 5498MB for the domain?

* nothing additionaly installed only up2date and plesk upgrades made

Any one has the same issues? or any comment?

============

when i run this

/usr/local/psa/admin/bin/php /usr/local/psa/admin/plib/report/autoreport.php --auto daily

i get this error

Unable to send report: plesk_mail() failed: Recipients list is empty.

how did it suddenly get empty? where will i add this?
