Are you really using spam.example.com? As far as I can see by telnetting to it, it does nothing - the address does not resolve. example.com is a valid domain that you can use for example or testing, but I don't know that using spam.example.com will do anything except add a non-existent mail server to the mix.
Note to self: Google before posting. I've found out why you've done it...
