I have received the "Matched a Filter Rule" message a number of times.
I have some control over what the headers of my messages look like, so
if I was told what the filter rule is, I could perhaps modify the
messages to avoid it. You probably don't want to post that information
to the list, but it might be worthwhile to send it privately to authors
of false positive messages.
