Bug Description
Refer to https:/
By default IPv6 privacy extensions is installed on Ubuntu server and temporary addresses are preferred.
This means that outgoing connections from Postfix will use the temporary IPv6 addresses, which will likely fail reverse DNS checks and cause mail to bounce.
Postfix should implement the requirements of RFC5014 and ensure that it sets the IPV6_PREFER_

Postfix gets used in many different situations in Ubuntu since it is the default MTA. In many of these cases, using the privacy extensions is perfectly appropriate, so I don't think that making this change by default is appropriate. For traditional MTA applications, I agree it should be set and it might be nice to provide this as a configuration option (I did get burned by this too the first time I set up postfix on an IPv6 connected host).
