[Evolution] suddenly junking good mail

[Carpet Nailz <carpetnailz researchintegration org>]

After years of working fine, Evolution (2.22.1.1 on openSUSE 11.0)
suddenly began putting email from my wife (coming from the same mail
server that I get email from) in junk. I haven't changed any of the
Evolution settings. Anyone have any idea what might cause this? And how
to fix it--marking the junked email as "Not junk" doesn't seem to
prevent its happening again with other mail from my wife.

Thanks.
