How can you fight that, besides dumping the client (recipient)
address?
You can't really - they are genuine rejects of forged emails. Depending
on how much of the rejected email is attached, sometime the reject will
be recognised as spam, sometimes it won't.

Doesn't that make them easy to detect? Recognize them as reject messages
by the subject line or other means, then check the body for something
(message id or subject?) that corresponds to a message in the Sent
folder for the claimed address? If there's a match, it's a real reject.
If not, bin it!

There are problems on more than one layer. Postfix doesn't neccessarily has access to the storage where the emails from the "Sent" folder are stored.

There is currently no design in Postfix to keep track of messages beyond delivery.

The easiest way would probably be to store the message id in a database and then check if the message id of the bounce is a hit or not. Even for that you would need a custom filter because Postfix has no internal mechanism to grap the message id.

It's probably a job for a policy daemon.
