Rated 5 out of 5 stars

The key to making this add-on work perfectly is to adjust the comparison criteria so that you know the messages that match are truly the same as each other in spite of having small differences in the body, which can happen. Thus the number of lines could be SLIGHTLY different and the size might also. For example, you might have an extra NULL in one, or an extra <LF>. Make sure you have enough criteria so you are confident of the found matches. The tool is great.
