Most of the user digests that I receive from the Fedora user's group (lists.fedoraproject.org) arrive tagged as junk. If I click the "Not Junk" button, Thunderbird reverts it back to junk in a matter of seconds. I occasionally get a message that I want designated junk. When I click the "Junk" button, Thunderbird reverts it back to non-junk in a matter of seconds. I see no pattern to which messages Thunderbird tags as junk, and which are not. These problems occur in multiple accounts, and in both my Fedora Thunderbird (current as of June 23) and in my windows-7 Thunderbird (current as of June 22). So the problem is neither OS specific, nor e-mail account specific. This has been happening for over a year now; it seemed to start in late winter 2015. I took this problem to the Fedora users group last July and tried everything they suggested. The discussion thread can be viewed starting here: "https://lists.fedoraproject.org/pipermail/users/2015-July/463378.html" Nothing worked. What do I need to do so: 1. Fedora list user digests are not tagged as junk? 2. Messages that I designate as junk remain so designated? 3. Messages that I designate as not junk remain so designated? If a bugzilla (or whatever bug-tracking tool you use) is needed, how do I submit one? Thank-you in advance. Bill.
