No medication to procure makes me sure there's no cure I am sure

Um, question for the general public (or people who are good with computer stuff/email):

1) How do I make multiple accounts filter to the same address?
-More specifically, how do I get them to Outlook?

2) Let's say I get...oh I don't know, 374 pieces of junk email to a single account about every week. How do I stop that, or am I screwed?
