How do you figure that? You deliver the message if it passes your border checks. If you think it’s spam after that, you can deliver it to the recipient’s spam folders where they are free to ignore it. You do NOT throw it away. >> You can reject who you want in Germany too, you just can___t delete a >> message that you___ve already accepted. > > What does "accepted" mean?
