Yeah. I am aware of that. It would take an island hopping attack. One of 
my outward facing servers would have to go and it in turn go after this 
server. I am just a little guy. I am behind on some updates but working 
to get current. Plus move to DNSEC for my domain...

I do have one Amahi server partially open, it runs my mail service and 
SquirrelMail. So 25, 587, 110 and 443 are open. So I do run SELinux on 
this one.
