Oh, I wish I could do that on my mail. Actually I have tons of e-mail addresses, which is wicked, but ok XD But the one I have the KofK account asigned to is the one without any filters. I mean it catches the spam, sure. But the site of the mail has some good agreement apparently and sends advertisements of super weird stuff and doesn't count them as spam because it was "sent according to the policy of the site blablabla". So I can't do anything about it besides just deleting the adds. the only mails it counts as spam are Binary opitons and generally stock exchange adds, then some sex adds and then... no wait I think that's it -.- And they come pretty rarely, so it makes my inbox full of we-fool-people-this-spam-isn't-spam messages
