[bogofilter - Open Discussion] RE: Sneaky 'invisible' obscuration text

[Dan Singletary]

Well, when I meant translating the colors, I meant translating "white"
or "red" to their hex equivalents.  The color names have defined color
values that they are associated with-- I think this is defined in the
HTML standards documentation.

a "font: color" type of tag would somewhat affect the classification,
but it still doesn't correct the fact that the majority of the tokens
from this email are contained within the white font area and therefor
not seen by the reader... just put in to throw off the spam filter.
Would bogofilter (at some point) be able to process the html in some way
as to recognize wether certain blocks of text would be visible or not
(either displayed with a micro small font, or with a forground color
equal to that of the background color).
