McAfee just published an interesting report as they are taking a different approach on Spam. They were looking at the environmental impact of Spam. So, how much energy do we have to invest in order to fight spam?
These are the key findings from their report:
And that’s just by using Spam-Filters! The whole report can be found here: The Carbon Footprint of Email Spam.
Needless to say that – if you are using Exchange you already have a good Spam-protection out of the box. You even get better with Forefront for Exchange and even better with Stirling:
I deployed Stirling, the next version of Forefront, on my Exchange Server. I have five active mailboxes (really a huge load ) and a few operational ones. The figures of Sitlring are very interesting:
During the last month, I got 58’636 incoming messages. My Spam-Filter found 57’439 as being Spam, which means that I had a Spam-Rate of 97.96% (and I do not know of any mail I lost in the transit).
If you look at the overview statistics, it looks like this:
The details of the connection filter:
And last but definitely not least, the performance of the filter after the mails passed all the connection-level filters:
What I like with the last statistics is, that the SPAM Confidence Level is either very high or very low but nothing in between. So, the filter gives me a clear message on whether it is SPAM or not. There is close to nothing which is “maybe SPAM” – it is less than 1%!
