Hotmail has an "unofficial official" policy of accept-then-drop for anything
it doesn't like. "Doesn't like" can be as simple as a single host sending
more than 2-3 emails to its customers, or can be spam.

It still does this and is one of the biggest headaches for deliverability
people going. 

There are ways to avoid this, but it's a lot of paperwork and involves
registering your MXs with Hotmail themselves, along with all domains
expected to originate from those MXs.
