Exclude mails from specific Inbox in "Inbox" view Is it possible to exclude a specific mailbox from the "Inbox" view in Mail.app?

I got 3 mailboxes in mail.app, 2 of them are mail accounts for normal mail communication, 1 is used for receiving mails from senders which sometimes send to much mail (newsletters etc.). The problem that occurs is that all the newsletter mails show up in the "Inbox" view preventing me to see the mails from the other mailboxes.
Update - Mail has a filter option to the right of the 'sort by' at the top of the email column where you can choose which mailboxes, or to only show unread, etc.
