You can't, the mta has no way of knowing what is being used to send the email ie telnet .in this case.

Reject mails on Postfix via telnet session

I think you can develop a cleanup filter (header_checks for example) that checks if the message-id contains @myhostname.mydomain .
This hasn't been tested and also it will reject some of the NDRs.
