Total sent emails on all domains?

[benbroad]

Hi, I was wondering what the best way of getting some overall server statistics is - specifically about email.

I need to know the:
1. total number of addesses
2. total sent this month
3. total received this month
4. total smtp bandwidth this month
5. total pop3 bandwidth this month

Any ideas? I fiure I can do the first one just by querying the psa database, but I cant think of a way to get the other info without going through each domain.

Any ideas?
