I didn't see the email that your message is referring to.

When I send mail to non-existentsupralog.com, the mail is handed
over to their MX host mail.atsat.com[195.10.32.19] which then sends
me a separate bounce mail that the recipient does not exist.

When I send mail to non-existentnovadata.de, the mail is handed
over to their MX host mail.novadata.de[193.99.189.1] which then sends
me a separate bounce mail that the recipient does not exist.

Both systems appear to be running "Internet Mail Service".
