Thunderbird occasionally marks some messages as junk but doesn't move them to the junk mail folder. I believe this happens when the sender is in my address book. The problem I have is that, when I mark these messages as "not junk", after a while they get remarked as junk. This is a AOL email address and when I Iog into AOL directly I see that these messages are not marked as junk there, so it appears to me to be a Thunderbird issues. Is there a way to stop Thunderbird from remarking these messages as junk? Is it not Thunderbird that's remarking them as junk?
