I have been playing with the email filtering capabilities built into Netscape 4.78 with Netscape Messenger. (I tried 6.x versions of Netscape and didn't like them)

Does anybody know how these filters work?

Specifically...

Are the key words case sensitive?
Are wild card characters allowed? If so, what are they?
How would I indicate a blank field as being a key word?
How would I indicate a non-blank field as being a key word?

I would like to see if the Netscape filters will serve my anti-spam needs before going to some sort of dedicated stand-alone spam filter.
