  I did check all the Windows machines for viruses and worms and found 
none...I will block outgoing port 25 however as soon as I learn more about 
iptables, looking into it today.  Thinking about getting a gui firewall 
configuration tool to get it done today but I would prefer to learn how to 
do things first before I get used to guis.

   So far I have only had one complaint about SPAM from my ISP so it is 
isolated but worrysome.
