This approach yields a high false positive rate. This can be a major
annoyance on mailing lists, when you get unsubscribed because of a
"matching" mail body. Your filter (which seems to be based on Nigel
Metheringham's system_filter) does not parse MIME headers but just
looks for filenames following Content-Type or begin.
This filter was the main reason for me switching my email from my
universities systems to my own system.
