The distributed form of the filter now uses \S+ to match the filename
part - its not perfect, but we are on a loser trying to parse MIME with
a regular expression in the first place.

The best thing to do now would be to make a very lightweight MIME
scanner which can handle things like rejections on types or filenames.
