I receive E-mails in both my "Junk" folder and in my "Spam" folder which are legitimate and I want E-mails from those senders to come directly into my In Box (so I don't have to fear losing important E-mails because Thunderbird ARBITRARILY routed them to "Junk" or "Spam" folders). My Thunderbird installation in Win8 provides a "Not Junk" button which presumably teaches the "Junk" filter that future E-mails from selected senders are "Not Junk" and should thereafter come directly into my Inbox. HOWEVER, E-mails Thunderbird ARBITRARILY CHOOSES to route into the "Spam" folder do not have a "Not Spam" button by which I can train the "Spam" filter that selected E-mail (and their senders) are legitimate and not spam. How do I get a "Not Spam" button to appear in the options for each E-mail routed to the "Spam" folder? This a serious need. Please may someone provide an answer to this problem. Thanks in advance for your help. Ron
