Allowing .exe files inside .zip files

[Mauricio Tavares]

	What is the best/proper way to allow a .exe file to be sent as an 
attachment when inside a zip file? I still want to have the zip file 
opened and checked for nasties, but if the .exe itself is ok, it should 
be left alone. Thanks to suggestions in the channel,

Maximum Archive Depth = 0

seems to do the trick, but I wonder what the cost is and whether there 
is a better way.  Any thoughts?
