Actually this is a valid case we haven't mentioned. There is no forward DNS either. That means we should also create that. The alternative is to disable IPv6 for the time being. Since smtp_address_preference[1] is 2.8+ and we run 2.6.6, we can only use inet_protocols[2]. Currently we don't listen on the outgoing IPv6 anyway so I don't think this has any negative impact. If there's no objections, I'm proposing we change inet_protocols from all to ipv4 this evening. [1]: http://www.postfix.org/postconf.5.html#smtp_address_preference [2]: http://www.postfix.org/postconf.5.html#inet_protocols When we've added the forward and reverse DNS, we can enable it again and properly support IPv6. > > Also, I'd much prefer that we finish the task of moving off the > > Linode host.

That means when we move away from linode, the reverse DNS management of that IP becomes irrelevant. _______________________________________________ Infra mailing list [email protected] http://lists.ovirt.org/mailman/listinfo/infra
