Comment 5 for bug 387321

This is in progress, though the SPF policy still falls back to softfail for now:

  $ dig +short -t txt launchpad.net
  "v=spf1 ip4:185.125.188.250 ip4:185.125.188.251 ip4:91.189.90.7 ip4:91.189.95.10 ~all"

Email from Launchpad is now DKIM-signed provided that its From: address is @launchpad.net or a subdomain (needed to comply with DMARC). The bulk of Launchpad's outgoing email is bugs, code review, and answers, and that now meets those requirements, but there's a long tail of other types of email we send that will need to be audited.
