The first try may have been the web bug, a small one pixel invisible image that must be called from a server like any photo or graphic. When it is, it leaves behind the address of where it is going. Microsoft made a programming language available to the entire world that does things inside Outlook, etc. Emails can carry programmed instructions of things to do. This is why virus and trojans and other nasties run rampant in the windows world. The same problem exists in UNIX and OS X but may be under better control and have fewer people trying to exploit it, or maybe the problem just has not been discovered or revealed to us Mac OS X users. Turning off HTML rendering in your email program is a start for protecting yourself but not a perfect answer. --- Since most spam is being sent by Microsoft OS computers, the answer to stopping SPAM seems obvious...
