I do not understand why a bounce should be generated (and not the
incoming mail to B would be tagged as spam and/or null-routed).
There is also a p=quarantine policy. Yahoo! and AOL, as well as
PayPal, LinkedIn, Facebook, etcetera use p=reject, though.
That said, the result of the above is that B is unsubscribed from
the mailing list due to large number of bounces, but that is
because B is recognizing the policy A is publishing.
B's domain need to do so in order to reject scams claiming to be
from banks or social networks.
Do I get this right?
More or less. Many people set up forwarding to an address at a
domain different from theirs, typically large providers, so there
are multiple places where the bounce may occur.
