The ones that I'm getting are all about 31-33K, and contains multiple lines
with garbage text (even the from-names and subjects seem to be random), and a
single image.
Training helps somewhat, but my main concern is that this is a long-term
(months, up to a year) project with the goal to poison peoples ham/spam-
databases.
Whatever it is it'll probably change the way that many view/use
statistical(ish) spamfilters today.
