Re: Possible quick fix
Bob...
New to information security and/or application development are you?
You're too fixated on an issue without looking at the entire requirement(s) a product is meant to provide.
You're 'solution' doesn't even come close to providing a work around for Exchange.
Also, thinking Linux is so much more secure than Windows is short sided and short minded.
Especially when both require humans to build and configure them--not to mention the applications running on top of the OS.
