The address is IPv4 localhost, while ::1 is IPv6 localhost. 
So, technically both forms are correct, and which one is preferred 
will depend on which version of the IP stack is loaded on your 
machine, and which IP addresses are assigned to your machine.

You need to check with your network administrator before you make a 
change like this.

Trend Micro has announced that they will cancel the stop.mail-abuse.org
mail forwarding service as of 15 November 2006.  If you have an old
e-mail account for me at this domain, please make sure you correct that
with the current address.
