Hotmail does account verification.
so if you are sending out from an address that doesn't exist it will not even deliver it.
Also.... If you are claiming to be a hotmail address...
(Ie your "from" is email@example.com)
....but you are sending it from your server... Then Hotmail will not deliver it as it knows what servers send out Hotmail emails and if an email "appears" to be from Hotmail but isn't coming from that server then it won't deliver it.
