Yes guys you sawd right.
MSN have a weakness .
What is that weakness ?
You can create what email you want , for example : owner@yoursite.com
All you have to do is enter here
Check the first one and click Continue. And at email put : owner@site.com
and complete that all things there.

I think thats a good feature, rather than a weakness.

That's how I'm able to use my Gmail address (shadab.chemistryonline@gmail.com)
for chatting via MSN Messenger.

This thing can be use for social engineering and hacking things !
I am good just to destroy .. but to remake no way
