[Beowulf] Apologies for the spam/virus yesterday

I would just have the end-user take care of the rare event of spam
getting through. They have to protect themselves already because beowulf
is not the only source of email for anybody.

I would vote for leaving it as it is.

I would hate to see this resource change into another form. It truly is
an *incredibly valuable resource* with a high signal to noise ratio and
virtually spam free - thanks Don.

I would also be willing to bet that the collective minds of this list
can figure out a way to keep it intact. Whether it be more automated
control or the assistance of some trusted members to do the "Turing
Test" work.
