No IPv6 subnets are in mynetworks, thus IP6 clients are not permitted to relay. Thus "Relay access denied." To fix this, choose one of these solutions: 1. Disable IPv6 in CentOS 2. Add the appropriate IPv6 subnet to mynetworks 3. Set inet_protocols=ipv4 You seem to have no need for IPv6 since you ignored it in your Postfix config. So #1 above is your best bet. It will likely prevent other headaches not related to Postfix as well. -- Stan
