When Mailfilter runs with debug support enabled, it logs the SMTP dialogue with the client. If the client sends arbitrary binary data, smtp_server_hdle_one() will send it unmodified to the logs. Binary data is inappropriate for logs.
Non-printable characters should be replaced with their hexadecimal representation before they are sent to the logs.
