An interesting article. I also did some reading on the DSPAM site. It
looks retty good, although I would imagine it's a little comlex to set
up for the owner of the Mac in question. There are also some links on
the DSPAM site to other filter software that I plan to follow up on when
I have a few spare moments.

Thanks for the response.
