The MX servers for Hotmail UK changed in DNS overnight. For those who are caching DNS or have hard coded DNS entries, you're going to run into problems with false positive "user unknown" bounces. Time to flush the cache and make sure you're relying on what's currently in DNS.
I'd include the specific domains here, and their new MX records, but I don't want to lead people down the wrong path of hard coding MX record entries, when they really should be relying on DNS.
