Sorry for the extremely late reply, but you can test using http://its-netzwerk.com/bscatter/ http://its-netzwerk.com/bscatter/
Alternatively attempt to send a message to a nonexistent address on your MTA using telnet which should throw an error after "RCPT TO" if the server is configured correctly

- cx42net 7y agoThank you for your reply. From my understanding, what you suggest is that a backscatter uses a return path email that does not exists? My understanding was that a backscatter uses an email that is not his, in order to deliver a message without sending it directly (and making the bounce server act like a spammer). Am I missing something?
- willbrowning 7y agoHere is a good blog post [1] that explains backscatter and some ways to help prevent it. [1] https://willem.com/blog/2019-09-10_fighting-backscatter-spam-at-server-level/ https://willem.com/blog/2019-09-10_fighting-backscatter-spam...
