I understand how SPF affects @postgresql.org addresses but I was under
the impression that it was no help for mailing list traffic since it's
being relayed so the ip address isn't going to match the records for
the sending domain anyways. For relayed traffic you need the verify
the DKIM signature (which is why it's important that the list not
modify the content).
