So I've been analysing a client's e-mail logs so I can set up better spam filtering for him, and after working on that I thought I'd check to see how much spam I'm blocking on my own server. I've been running WebWizardry.net for about five and a half years now, and several people have their e-mail hosted there. So, how much spam am I blocking before anyone even sees it?
Well, the average for the past four weeks has been 2,531 messages blocked per week, which works out to just over one message blocked every four minutes. That doesn't include the spam I get for phroggy.com, which is hosted at SlickHosting.com. And of course, my users assure me that a lot of spam isn't being blocked.
