Ok, when I do a diff, it seems like everything starting with the headers
has been changed. Every line is shorter on the message that went through
MS. I don't know if this  matters, but diff is showing it as changed
between the two. There are obviously headers added by MS.

Is there anyway to tell MS not to scan any messages in anyway from a
certain sender? Or how else do I deal with this? The person getting
these signed messages is riding me on this issue.

Thanks,
Max
