Our spam rates run between 60%-85% spam depending on the volume of real mail
- the amount of spam we get remains pretty constant at between 1.1 and 1.4
million per day.

Are other institution's spam levels this high?  I would be very
interested in hearing stats as I thought global rates were only
around
90-95%.

We deliver around 3 million messages per day to users inboxes, 87%-93%
of which we identify as spam and filter to a spam folder on a regular basis.

That doesn't include the very very large number of attempted
deliveries from SMTP servers that try to pipeline data which are blocked, or
the 20%-25%
messages which are discarded at our edge servers due to an extremely
high spam score.
