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.
