[Mimedefang] non-virus executables

Then you have to assume that the recipient has an unzip utility
which often isn't the case for the customers we support.  I'm
really only concerned with things that cause mailers to pervert
the meaning of 'open' into 'execute the contents of'.  Social
engineering tricks of including instructions to rename or unzip
wouldn't be that much different than the one step of saving before
executing.  Could we change the MIME type to application-octet-stream
on questionable parts - or at least something mailers won't ever
launch?
