[Esd-l] Yves Agostini's script

What I meant to say was that setting the "MANGLE_EXTENSIONS" variable to
'zip', which is what the example Procmail code in testzip.pl does is not
enough to actually strip or poison the zip attachment as I understand the
Sanitizer.  The extension also needs to be in "poisoned" or "stripped" for
something to actually happen.  Right?  

I'm trying to understand why this was done in the sample Procmail code in

Seems like this should do the following:
1. See if zip contains dangerous executable
	a. If yes, mark message as "discard"
	b. If no, send it on unaltered
I don't understand what the "mangle" state if for?
