The score on these messages is reflected as the following from the
header.
SpamAssassin (score=1.573, required 10,
        autolearn=disabled, HTML_20_30 0.50, HTML_FONT_INVISIBLE 0.07,
        HTML_IMAGE_ONLY_24 1.00, HTML_MESSAGE 0.00)

I'm using the latest 2.6.x spamassassin variant, I don't believe I'm
using the Mail::SpamCopURI module (although I use spamcop in my
