I did an experiment by posting a temporary account in the From header
in a bunch of different fairly high-traffic, high-spam groups as well
as the ones I regular. Six months later when I remembered I had
started that little experiment, the box was still empty.
This doesn't surprise me at all, though: how many times have you
gotten a spam that starts off "This is a text-only section for people
with older[1] mail readers incapable of viewing HTML" and then leads
right into the HTML spam...

current version of mutt...
