I actually have two problems. 

1. When I signed up for the alias account, it gave me an option to have the emails for each separate email address to go into separate folders.  I unfortunately did not choose this option and so now it is hard to see which email address the actual email came in on.  This way I could figure out who still needs my new email address.  I have found that there is no way to get back to this option without using a 'rule' which does not seem to work.

2. So I created a folder and moved all the inbox messages to that folder so that the new messages I could then start to sort. Well, on my phone they are all jumbled up.  I have duplicate emails under each email address in my phone.  And all the folders on the account are listed under the original email and not the alias that I have marked as primary, so I can't just delete the old email from my phone.  Otherwise I can't get to the other folders.

This is such a hot mess. How do I...  1. Get the emails separated as they come in and 2. fix the cross over issue on my phone?
