Spam CSI is a donationware (free to use but a donation requested) offering, about 6 MB download. It seems to do a pretty good job of finding the sources of the bits of spam that are sent me. Outlook is required for full use of this product (the integrated spam reporting) so I was unable to test that part of it. Here's the link at FreewareWeb: http://www.freewareweb.com/cgi-bin/archive.cgi?Category=E- mail+Clients+%26+Tools&sb=0&so=descend or: http://tinyurl.com/8swe Spam Punisher is another freeware on the same page- its a little smaller and simpler but also works pretty well. Both of these are a little like having Spamcop on your system. :) TTYL, Bill Holmes
