I'm not sure I follow. If the SMTP server required authentication, your PL/SQL procedure would get an error indicating that your message was rejected because you didn't log in. If the message was delivered, that indicates that this server doesn't require authentication. If you have some other application sending mail that does send a password, I would be very suspicious that the two applications are not using the same mail server.
If you do change to use a mail server that requires authentication, you should be able to add
utl_smtp.command(conn, 'AUTH LOGIN');
utl_smtp.command(conn, utl_encode.base64_encode(utl_raw.cast_to_raw(<username>)));
utl_smtp.command(conn, utl_encode.base64_encode(utl_raw.cast_to_raw(<password>))); to your procedure after the utl_smtp.helo call.
