 Just reread the first one to this list, it was by me and it included the URL
to the story.

 The significance is simply that software, like SA, might look for certain
headers in certain locations in e-mails; but although not commonly used these
headers can contain a kind of comments... and adding such a comment will break
a lot of software which wasn't written to follow the specs... meaning that some
spam- and anti-virii software might miss these e-mails.

Instead of
        header: information
these headers might look like:
        h(f)e(u)a(c)d(k)e(u)r: information

 So when the "simple" software searches for "header: " it can't be found, so it
just assumes that there are no such headers in the e-mail; then the more to
specs mailreader finds "header: " resulting in maybe a virus being activated or
spam decoded and shown etc.
