Yes, i know. But i think that when we ban 'all' dangerous extensions, eg 
.vbs/.exe/.reg/etc all files that have double extensions eg. something.doc.exe 
will be actually blocked.
 From my own experience i can say, that many people use dots in filenames that 
they send in e-mails and that files eg. document.eng.doc  ('eng' from 'english')
are stopped by default rules.
Ofcourse this rule can be simply turned off, but maybe it could be turned off by 
default as, in my opinion, it more hurts than helps.
Or...?
