You can now turn on multiple inboxes in Labs under the mail settings.
Set up as many aliases as you want on your account in seconds and then turn on and configure multiple inboxes for them.
After enabling multiple inboxes, a new settings tap called "Multiple inboxes " will appear where you can configure all your inboxes to catch individual emails. Enter the search parameter "to:address@domain.com" Providing you have an alias or forwarding for emails sent to "address@domain.com", emails will pile up in your special inbox for them.
