Remarks

The policy is the whole of what an account is willing to have written into the collected origin, and it answers two questions rather than one. A message may say of itself that no person wrote it, in which case none of its addresses is considered at all; and an address may name something other than a person to correspond with, in which case it is not considered whatever message carried it. Both are refusals rather than scores, so an address the policy declines is never recorded by any later reading.

Three rules refuse an address, and they are deliberately of different kinds. AutomatedMailboxName is structural and every deployment gets it, because it names what nobody corresponds with. The Exclusions are the owner's, because only they know which of their real correspondents they would rather not have written down. And the deployment's own mailbox addresses are refused because a contact book holding its owner is a book that answers "who is this from" with the person asking.

Everything the policy holds is personal data: an exclusion names somebody, and an own address names the owner. Nothing here may be logged, and the policy carries no identity of its own for a log line to name instead.
