  Baseline written by 0-working/probe-domain-security.py, then extended by hand with the
  additional Blueground hosts probed during contract discovery. The script reported
  `spf: false` because theblueground.com publishes its SPF policy as a MULTI-STRING TXT
  record; `dig +short TXT theblueground.com` confirms `v=spf1 include:eu.transmail.net
  include:mail.zendesk.com include:_spf.google.com include:_spf.salesforce.com
  include:aspmx.pardot.com ... ~all`, so spf is recorded true here.
