Right now, we do the fairly safe thing of choosing the maximum number of
domains randomly from the list.  Eliminating invisible ones would be a
potential disaster since spammers might be able to figure out a way to
make domains appear to be invisible to our renderer, but be VISIBLE in
some mail programs.

I'd favor an approach that would give slightly better odds (like 2-to-1)
for more visible URLs over less visible URLs, but I think a larger shift
would be too juicy a reward and possibly lead to a lesser disaster.
