I would like to put in a request for adding the ability to put top level domains in my blacklist (or whitelist, I suppose). Given that the only email I receive from certain TLDs (*.cn, *.gr, *.fr, for instance) is either spam or viruses, being able to target those domains in the email/antispam products would save me a lot of the time I currently spend in my email program, searching for everything from those T LDs so I can mark them for my junk filter.
