the procmail example in linux-sxs

[M.W.Chang]

I've got my procmail sort of working.

1. if I want all users to use one prcomailrc, does it mean that I only 
need to put a procmail file in /etc? Right now, I have a .forward and 
.procmailrc in /home/user.

2. is it silly using procmail to catch spam by actually reading and 
hence understanding the message body?

3. So I only need to download the filter from the supplied URL and it 
would be working without additional changes needed?
