It's been a long time, but I finally found out the cause of this
problem. Matt, one of the Mozilla Thunderbird support moderators,
"Sounds to me like you are using Yahoo IMAP. That is certainly how
their spam guard works. It keeps re instating spam statuses."
Matt and a "top 10 contributor" (Zenos) imply that Mozilla cannot do
anything about it. It seems the problem is in Yahoo's software, and
is solvable by neither us users nor Mozilla. So I'm marking this
"CLOSED" (not "SOLVED"). I thank Joe and Rick who tried to help,
Ed who tried to help off-line.
Yes, and gmail... I thought this was answered quite some time ago.
You will have trouble getting a mail client to accept mail as being
not-junk when the mail comes with headers that say it is junk. If you
were to circumvent that, all externally-determined junk mail is likely
to get passed through as not-junk.
You'd need to use a better mail client, that lets you set priorities of
what un-junks the spamminess rating. So that certain list headers get a
very high rating.
Or, receive your list mail from a different address not served by yahoo
or gmail, while realising that choosing a different service that works
now, may inherit the same problem at some future time.
Really, a better way to handle mailing lists is a newsgroup server. But
I'm less than impressed with the news clients I've tried on Linux, so
I've never bothered using the gmane news gateway.

All mail to my mailbox is automatically deleted, there is no point trying
to privately email me, I will only read messages posted to the public lists.
George Orwell's '1984' was supposed to be a warning against tyranny, not
a set of instructions for supposedly democratic governments.
