I have one email that will not allow other emails to forward to it (inbox doesn't accept) but on the account list it is the only email with a colored star next to the account name... any ideas

Problem

* Recently this account has stopped accepting emails either by auto transfer or by cutting and pasting emails into the inbox and also by cutting and pasting from a folder within that email account to the inbox.
   

       When looking at the account settings, I noticed that the account in question with the input issue also, next to the account name, has a mustard-yellow-colored star that none of the other accounts have. I don't see anywhere in Help, Technical, or whatever any meaning for what that means. That's where I think the problem lies. 
   Potential Solutions
       As a workaround I have started forwarding emails from one email into The account in question as a clearing account this clearing account. That involves taking an account from Gmail (as an example) and forwarding it to a folder that specifically is for input from Gmail ... but then the filters don't always work because they're not going through the input box. 
       Do you have any suggestions or fixes that I should be aware of and try?
