[courier-users] Pythonfilter attachments

[Alessandro V. <ve...@ta...>]

Hi all,

I revamped attachments.py in order to catch Javascript Trojans inside a zip, 
which were driving me crazy.  While I added that, I removed the configurable 
archive.  The attached flavor of the filter rejects just the extensions 
hardcoded in the source.

Enjoy
Ale
