My original message was vague; my apologies.  The Fedora list messages 
were not being put into the "Bulk Mail" folder.  Rather, they were being 
flagged with a little "flame" symbol in the inbox table of contents, and 
between the message header and the message body.  Clicking the "Not 
Junk" button clears that flame symbol, but it reappears again shortly 
after.  Also, not all fedora list messages are flagged with the flame 
symbol; but most are.  I see no pattern as to which are and which are not.

Thank-you.

I tried that.  No change; same behavior.  It also doesn't matter when I 
set the filter to be run.  I checked for other user filters; there are 
none.  I have several e-mail accounts in Thunderbird, but this problem 
shows up only for Fedora list messages, and only in the one e-mail 
account that I use for the Fedora list.  If I recall correctly, this 
problem started showing up in late spring.  Is anyone else seeing this 
behavior?  Is there something in the Fedora list message headers that is 
bugging Thunderbird's spam-checking code, and can be adjusted?  This 
seems to not be a Thunderbird issue and not a Fedora issue, but a Fedora 
list issue.

thanks,
Bill.
