There is a semantic difference:
* With "none" no verification of the destination is expected and
no reports are generated on verification "failure"
* With "report", verification is expected, and failure reports
may be generated, but delivery proceeds despite failure.
The request to "report" failures is subject to the usual downgrade
protection (except on cold-start, loss of state at the sending MTA,
or too little traffic to keep the cache "warm").
