I am using this code for filter MS-Office attachment and to send an
automatic reply mail. Today i noticed that this recipe also matches on
PDF-Documents? Any idea why? The recipe is OK if all four "*" lines are
fullfilled, isnt it? So, if there is an attachment named name=file.pdf
it should not match this line? But it does!

Thanks,
Tom
