Need Clarification

Could you explain this further, as I'm not sure what you're saying.

Live Mail will only let me sign up for one account, though I can have a certain number of "aliases". However, they all get each other's mail. I have one Live Mail Inbox where I would like to collect my mail into the different email accounts, and have them only receive the mail that is specifically addressed to them. Is this possible?

I'm using Windows 7 on a laptop.
