I do not want to permanently delete everything Windows Live Email sees as potential "junk mail," as they are often incorrect in their assumption of what "junk" is. However, once I specify a sender or sender's domain to be in the "blocked sender list," it simply goes to "junk mail." I continue to receive their phishing and crud mails. How can I set Windows Live Email to permanently delete any mail from a specific sender or their domain?

Surely in the year 2012, this should be a possibility. I appreciate any help.
