[Evolution] Suddenly lots of good stuff in the junk folder

[Jonathan Ryshpan <jonrysh pacbell net>]

I use spamassasin to check for junk (local tests only).  Suddenly I'm
getting lots of good messages in the Junk folder, usually about 40 per
day (I'm on a lot of mailing lists (8-)).  There have always been some
misfiled good messages, but usually only 3 or 4, along with a fair
amount of spam.  Now lots of good stuff, very little spam.  The
situation changed some time after Christmas, maybe just after New
Year's.

Does anyone have a clue what's happening?

System details:
        Fedora-11 with all upgrades
in particular:
        evolution-2.26.3-1.fc11.x86_64
        evolution-data-server-2.26.3-2.fc11.x86_64
        evolution-spamassassin-2.26.3-1.fc11.x86_64
        spamassassin-3.2.5-5.fc11.x86_64

Thanks - jon
