Hi Randall,
Yes, this box is in production. It's a vanilla build of Ubuntu 8.04 and Zimbra 5.0.11 OSE. It handles e-mail for 7 domains. I've been using IPv6 for about a year now. It is dual-stacked and still uses IPv4 for internal stuff like ClamAV.
Replace the 'x' with your IP addresses. It's just the Postfix MyNetworks variable to set who's allowed to relay.
So it might look something like '127.0.0.0/8 192.168.0.0/24 [::1]/128 [3ffe:ffff::]/48'
Don't forget the [ ] to determine the address is IPv6. |
