[exim] Finding largest senders

Hi again,

We are currently using the command below to find the 30 largest
authenticated senders on our exim mta's so we can check if it is valid
email or spam:

grep -h '^-auth_id' /var/spool/exim4/input/*|sort'|cut -f3 -d"
"|sort|uniq -c|sort -rn|head -30

The problem with this is that it only counts emails and not recipients.
We could have a spammer with 5 emails with 1000 recipients in each and
we wouldn't notice from the list above

Is there an easier way to do this maybe with exipick instead of having
to go through the emails for each sender and count recipients then add
them all up?

Thanks

Murray
