Port 25 on "mail" or "smtp" is a valid smtp relay not requiring any authentication for more than half of ISPs. The Windows resolver will fill in the domain part of the relay host name. I have seen no claims that any spamware *at the moment* goes any further than this, although of course as time goes by it will do whatever is necessary.
