E-mail bandwidth is not accounted in the stats

[dicarsio]

I have an account which uses almost exclusively e-mail (via IMAP). It must do at least 500Mb per day of IMAP/SMTP traffic a day but the statistics are not accounting them, only about 10mb (which I assume is for DNS or Web).

Does anyone has this issue as well?

I the account stats are only looking at the web bandwidth.
