True (and I agree with the criticism of Microsoft for this "feature"), however I don't believe that any filtering system needs to look at anything other than the final extension - since that is what Windows will pay attention to if the user double-clicks on the file attachment. What comes before the final extension is irrelevant, and could be anything from "a" to "gif.jpg.pif.com.doc.scr.wav.avi.mpg".
