Re: Extremely High Spam Statistics

Hi Tim

Some stats from this part of the world.

Yesterday we had about 1.1 million smtp connects.  We rejected 42% of
these.  Of the remaining, a further 33% were flagged as spam.

This gives us about 61% of incoming email is caught as spam. This leaves
less than 20 other emails per user per day, which seems reasonable. We
do have some spam that gets through, but not a lot.

Your spam % seems very high, and your total valid messages seems low.

I would be interested in comparing our spam stats with other
institutions.  We are currently sent around around 450 000 emails per
day, of which 98-99% are spam leaving around 5000 valid email messages
passed through.  This is transparent to our uses who only receive
valid email.

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