Hi everyone. I have a mail server and as almost all people I don't want spam messages - it works - I don't receive them, but when my server receive spam message and it is spam message, the server reject it and send report to sender. In report is an attachment - received message with spam. So, if my server receive a spam message from Outlook server, then send the same message in report to sender. In result Outlook server add my server to banlist because my server is sending spam to them... very funny, but it's real. How can I prevent to send message in attachment in this case? I'm thinking about: 1. Drop message and do nothing. 2. Drop message and answer about spam and attach only headers.
