Is there something that changed recently in the way postfix refuses mails when they are considered as spam ? It looks like it tries to answer to the sender address, which is most of the time false.
554 5.7.0 Reject, id=23712-05 - spam (in reply to end of DATA command))
This makes my ISP smtp (smarthost) consider me as a spammer. And I found a lot of non deliverable mails in the mail queue.
Any idea how to make postfix simply throw spams away instead of answering ?
