[ale] vm interface config

[Wolf Halton]

My first question was going to be - does the public address have the 
ports open..

Starting Nmap 5.21 ( http://nmap.org ) at 2011-07-23 01:31 EDT
Nmap scan report for 66.170.20.226
Host is up (0.040s latency).
Not shown: 989 closed ports
PORT    STATE    SERVICE
22/tcp  open     ssh
25/tcp  open     smtp
53/tcp  open     domain
80/tcp  open     http
110/tcp open     pop3
135/tcp filtered msrpc
139/tcp filtered netbios-ssn
143/tcp open     imap
445/tcp filtered microsoft-ds
993/tcp open     imaps
995/tcp open     pop3s

This may be old news, but the most likely issue was that and it appears 
your mail services ports (25, 110, 143, 993, 995) are all open.

Is this issue still persisting?  The systems I manage are all vms and 
NAT does not appear to affect them.
