sporadically most of the junk mails from a POP3 account in the junk folder are marked as not junk (right after you started up thunderbird)
Maybe only the new junk mails (the ones that came in new with the startup when you found the bug) stay marked, all others were unmarked as junk.

Reproducible: Couldn't Reproduce

Steps to Reproduce:

Actual Results:  
Most junk mails are marked not as junk in junk mail folder.

Maybe related to bug 259784?

[Stefan Geisseler]

It seems to be the same...
But why are all those bugs marked as duplicates of another fixed bug, which one is completely different from this one?
In addition, this one here isn't fixed.

The filter works fine and automatically marks detected spam and moves it to the junk folder.  But if I manually mark as email junk, it moves the email to junk folder but does not mark it as Junk. I have to then manually go to the junk folder and remark the email as junk in order to train my filter.  this is a consistant problem.

i've the opposite problem:

sometimes junk filter marks some mails as junk (i see the bin) but doesn't move to spam folder.

i can move manually or (as i do cause it's faster) i use to mark as "not junk" and remark as junk.

this happens rarely but happens!

Do you have "Trust junk mail headers set by:" turned on? 

See also:

Bugzilla Bug 323159
"Trust junk mail headers set by:" should be consistent in UI and log location/access

I can confirm this : sometimes, when a new message arrives in my Inbox, it is correctly detected as junk and moved to my Junk folder. But when I look in my junk folder, it is not marked as junk.

What I can see is on this kind of mail is :
* They are in the future
* They contain cyrillic characters

With further observations, it seems that these two cases are causing mails not being marked as junk :

* The mail date is in the future
* The mail belongs to a thread

[Wayne Mery (:wsmwk)]

To Hyle and all - do you have "Trust junk mail headers set by" ON or OFF?

Reporters, does the issue still occur in the latest supported Thunderbird 2.0.0.x or trunk nightlies?

I see this problem on build Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1b3pre) Gecko/20090119 Shredder/3.0b2pre. on several POP3 accounts. 'Trust junk mail headers set by' is set to OFF.

Please, take a look at this (https://bugzilla.mozilla.org/show_bug.cgi?id=471503) bug. It seems it is related to this problem someway...

The original description of this in comment 0 is bug 471682, at least as I have interpreted it. Duping, since the later bug has generated a lot more activity than this one.

Cannot understand why this could be considered a duplicate of bug 471682. In any case, it's not resolved.

Tb 2.0.0.21 (20090302) on POP3 has stopped marking spam as junk but still moves
it to junk folder. It also doesn't add flag when i manually mark spam as junk,
and it has also removed all old junk flags in the folder that were there
before. It even removes flags (not immediately) when i mark messages in the
junk folder. Interestingly, Tb does add the flags when the same messages in
another folder in the same account are manually marked as junk, and the problem
does not exist in the other accounts. 

I remember having had this problem in the past (but don't remember what got rid
of it), and i remember seeing forum posts about it, but i couldn't find any bug
report besides this one, and i couldn't find any interesting forum threads.
