downloading all email in all folders

When I open my client, I set up that it opens in main box. Here the client downlaods all the new messages. Now, I have other fodlers created with the same email address with specific filter. When new incoming email are directed to those directories, the client does not downlaod the messages, but it shows only “…” near the directory that contains new incoming email. However, when I open the dirctory, the email are not there, and the client needs to download them. IS there a way to downlaod all the incoming new email and show the number of unread messages?

Maybe witn an imagine I can explain better .

I am talking of the 3 doots near the name of the folders
