[AusNOG] IPv6: Who's dual stacked? Why don't I look stacked?

[Don Gould]

Ok let's see what answer that gives us.

thinkdesignprint.co.nz>_ ~# postconf inet_protocols
inet_protocols = ipv4
You have new mail in /var/mail/root
TDP:thinkdesignprint.co.nz>_ ~# nano /etc/postfix/main.cf
You have new mail in /var/mail/root
TDP:thinkdesignprint.co.nz>_ ~# /etc/init.d/postfix restart
Stopping Postfix Mail Transport Agent: postfix.
Starting Postfix Mail Transport Agent: postfix.
TDP:thinkdesignprint.co.nz>_ ~# postconf inet_protocols
inet_protocols = all
TDP:thinkdesignprint.co.nz>_ ~#

Sorry for the list noise, I'm not sure where else I can email that I can 
prove this.
