New msn contact list protocol?

Question

I was wondering if somebody knows how the msn contact list protocol has changed. More specifically: in the old Messenger, if I deleted a contact, I couldn't "completely" delete it using the list that was found under options -> privacy, unless that contact had deleted me as well. As a result, even if I deleted a contact, I could still get a lot of unwanted e-mail from him (i.e., massive forwards).

I have very few contacts under a new address now, and I've noticed that I haven't got that kind of spam from a couple of contacts I've deleted. So my questions are:

1) In the new protocol, if I delete a contact, is it really deleted (I guess this means deleted from the server too), unlike in the old protocol?

2) If I delete a contact but he doesn't delete me, can I still receive e-mail from him, or does hotmail finally understands now that that's unwanted email?

Thank you very much.

You may find this Wiki about the MSN Protocol of interest. Do note that some parts are incomplete

You can always receive e-mail from everyone unless you specifically block them, and Hotmail's block list (if there is any) is not related to Messenger.
