I have a computer running as my firewall. I am using Astaro's now know as "Sophos" Home "FREE" firewall. This takes care of alot of problems for me and my family. I also run 2 mailservers "Debian" These are one in front of the other. I do not get spam at all. I may get a message or 2 if I sign up for something but after a couple of days I usually have it covered. My question is am I not normal to have these things. The computers are not that old. They are my old set-ups from the previous year or two. My new Spam filter is using a 360 gig? SATA6 drive with 12 gigs of ram. But I look at all of these questions about "I have been hacked" I do not think I have had to worry about this for years. I get approx 400 emails a day through my personal server serving 4 people. Are most of you putting these servers up in a company environment? or are they for home as mine are even though I am running a fix it business from home.
