Exchange Hosted Services
I got this interesting mail the last week demonstrating how effective Exchange Hosted Services (EHS) is at filtering out spam. The volumes of mail sent are quite staggering. I'm including the original email message and the graphs for you...
"What I wanted to do is illustrate to you the size of the problem you are facing today. We all know spam is a big problem – but how does that translate down to you. Below are email analysis of two EHS customers over the same time period; one of 250 users the other of 16,000 users. The images are far more powerful than any words or statistics, and what you see represents huge pain points in administration and associated cost for those not using a hosted solution. They are presented in two slightly different perspectives, but the ratios apply across all market sectors. Note how consistent the legitimate email is as opposed to the growing level of spam – in the space of 62 days.
Exchange Hosted Filtering removes this growing threat of spam and associated malware away from the gateway by providing an upstream Internet based filtering service, so ensuring that only legitimate email is routed to the gateway. EHS Filtering brings further defence-in-depth to any email architecture and significantly reduces the load on gateway architecture and bandwidth.
As we enter the festive period then the trend over recent years is for this level of spam to rise substantially, we are already seeing emails from Father Christmas. On 22nd November 2006, in one day we filtered 442,003,805 unwanted messages, representing 93.48% of our total network traffic. "
That is a HUGE amount of spam - and now I know why I haven't received any response from Father Christmas to my mail.... :-)
