[Bug 1089342] Re: Postfix uses temporary IPv6 address for outbound connections

[John Kim]

Updated the description with link to the possible page of concern.

The serverguide for saucy doesn't have postfix.page.  Has it been
dropped deliberately?

  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).
