[exim] Computing Bandwidth per user account

Hi all,

How can I compute total bandwidth consumed by a specific account (daily basis)?
I need to know the incoming + outbound bandwidth consumed by each domain account.

I try Eximstats and Isoqlog, but both do not compute the correct traffic for each account.

Any ideas? I can't found nothing that works searching in Google ...


Gimme a light please!


Regards,

Paulo Antonio
