This zip file passes the .exe banning why?

[Alessandro Briosi]

Hi all,
The file you can find here [1] bypasses amavis extensions checks.

In my configuration .exe are banned (even inside .zip files)

Though for some reasons this .zip passes.

I also have checks for double extensions which on normal files work
(still even within .zip files)
I also tryed renaming the file (leaving the .zip)

This one bypasses the checks and I'm probably too dumb to find out why.

Any help would be appreciated.
 
**N.B. Obviously it's a virus so do not execute the file!!!!!!**

Thanks,
Alessandro
