238926 - Junk Filter occasionally moves message to Trash even though not so configured

Status: VERIFIED INVALID

(MailNews Core :: Filters, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040113

I have Mozilla configured to use POP and store all mail locally. The
Junk Mail controls are configured to move junk to a folder named
"Junk".

About 5% of the mail that Mozilla identifies (and tags) as junk gets
moved directly to the Trash folder (incorrect), while the other 95%
goes, correctly, into the Junk folder.  I have a number of other
filters active but no filters are defined that move mail directly to
the Trash.  This problem seems to affect only junk-flagged messages,
not messages handled by other user-defined filters.  I have also
double-checked that no filters point to missing folders.

I have not been able to discern any pattern to which messages get mis-
filed.

This is not a problem with categorization: the messages *are* junk;
just a problem with where the messages are moved to.

A Bugzilla search on keyword 'trash' didn't turn up any obvious
duplicates.

I turned on junk filter logging and message filter logging and waited
for another mis-file.  I got four.  All of them show up in the junklog
where it says it moved the messages to the Junk folder.  None of the
messages are in the filterlog, so they are not being moved by filter
rules.

In Junk Mail Controls, there is an option:
[] Automatically delete junk messages older than [xx] days...

If the mail arrives with a bogus date on it -- i.e. one that makes the message 
appear older than the age limit specified in that option -- then (perhaps; I 
don't know the exact sequencing here) the messages can be moved without 
appearing to have landed in the Junk folder.

Thanks, you were correct.  I unchecked that setting, and it has stopped
placing junk directly into the Trash folder.

Changing to INVALID.
