While I usually restrict myself to software, occasionally I find a web site with useful information and just have to mention it. Today, I discovered a very nice site that explains how to read email headers and determine where they really come from. While most people get far too much spam to make it worthwhile to trace every piece, there are times when you may want to know where an really email came from. This web page tries to stay as clear and non-technical as possible, but as the subject is technical, it does not really succeed. However, it is the best page on reading email headers for the non-technical person I've seen. Head out to this site and bookmark it. That way you'll be apply to find it when you need it.
