It is off topic, but worth reminding everybody once in a while.

OS 9 it is turned on automatically, just the way the OS is designed. OS 
X leaves a couple ports open that could be hacked and have to be closed 
manually. A hacker who trys to locate my machine checking for ports 
won't even get a reply. It will be as if there is no machine there. My 
machine responds only to querys that it's expecting.

In OS X, if you have windows file sharing turned on you have a port 
open. Probably if you are using the personal web serving too.

It's fun to run a mac on one of the online security checkers designed 
for windows. Nearly always gets very high marks. Except those that test 
your browser. I have java, active X and cookies all enabled. Not a big 
problem with a mac running netscape, but a security risk if it's a 
windows machine running IE. My understanding is that it's a way that a 
outsider can access all the spy files microsoft is keeping on you. As 
well as mess with the contents of your HD or install a virus.

It's probably which emailer we use. I use Netscape 7. Spam catching is a 
case of looking for certain key things. It could also be that Evert used 
some word that set off your spam catcher.

My unwanted mail is split between windows viruses mailing everybody and 
spam (which is mostly porn or get rich quick). My ISP provides a spam 
catcher at their level and that catches some of the spam. On a slow day 
I may see only a few virus emails come in, on some days it can be dozens.
