That is (was, they've improved it a lot) the number one cause
of script kiddie virii. Simply viewing a mail message in the
preview pane was enough to trigger a script. They have
improved security greatly in the recent patches though.
But HTML mail has similar issues. If someone handcrafts an HTML
browsers sandbox technology to protect you. And if its Windows
and WSH is enabled the script can read/write the registry...
The ability to script documrnts is powerful, but potentially
dangerous, just like eval/exec (which are how such
capabilities are typically implemented!)
