The problem is that the length of 'xyz' will probably be on the same order of magnitude as the length of your message - if it's only 2-3 digits long, you'll probably find a matching location in the first 100 or so digits. But if you need a run that's an exact match for an entire 20K email, you're going to have to go down a long ways to find a match. (protip - compressing the email text first is a big win here)
