Our office uses Messaging Architects GwGuardian for GroupWise and for 2007 total received email was 8,105,000 and of that 7,273,000 was rejected as spam. That's about 90% rejection and in the remainder there is still some spam that gets through, although it is a trivial amount. I'm not sure I am seeing an increase in the amount of spam compared to the previous year where it seemed we were receiving over a million emails a month. Spam is a really big problem and I pity the IT department that isn't using some type of filtering before it reaches their email servers.
