I take that to mean simply installing all the spam-fighting services, extensions, daemons, etc.. that already exist. Or, perhaps, creating a monster bundle with an integrated assortment of spam-fighting tools. I think it's OK to brainstorm new approaches.

Extend what exists already before you go writing something from scratch.
