I've been asked to supply the stats on how many inbound and outbound, and internal emails we have on our system.

The only way I know is in GWMon I can go to the GWIA and see inbound and outbound.
I can also log on to each site via the site.dom within gwmon and look at MTP Status.

But these reset every time the site is shutdown and restarted. Is there anywhere in the Admin Console that is a one page that shows the stats.

(I restarted all our servers last week so the stats within gwmon are only 3-5 days, I know i can either wait, or divide and times by x to work out a weekly average, but I wondered if there was another tool that showed them better).
