This matches, to almost the decimal place, what we're seeing in our ISP
operations.

Tim Lane spake thusly:
>I would be interested in comparing our spam stats with other
institutions. 
 
According to our current email statistics, our email traffic is about
 
10% legitimate
0.2% viruses
89.8% spam
 
Appox 1.1 million emails per day.  This includes all internal emails,
though, so the proportion of internet-originating email which is spam is
going to be higher - so this ties in with the 90-95% figure you quoted.
 
We identify the spam via greylisting, invalid email address checks, and
Spamassassin checks.  We have a very good hit rate for spam, with very
little getting through - 98% spam seems pretty high.  However, your
scanner may be better than ours :)
