Postfix uses temporary IPv6 address for outbound connections
Status in Ubuntu Server Guide:
Status in “postfix” package in Ubuntu:
Refer to https://help.ubuntu.com/13.04/serverguide/postfix.html
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_SRC_PUBLIC IPv6 socket option (or possibly
provide a configuration option to enforce that requirement).
