I think we'll see the following stages occur over time:
1) receivers use SPF for whitelisting
2) receivers start honouring "-all" and rejecting
nonconformant mail. (requires forwarders to upgrade to
SRS/SUBMITTER.)
3) if a domain doesn't publish, apply a default of "a/24
mx/24 ptr -all". (requires vast majority of legitimate
domains to publish records.)
