Hotmail Spam blocker going crazy against IP addresses

It seems that Hotmail spam filter is going mad, they decided to block email from IP addresses, it just happen for my company this week and we thought that we will have to invest to upgrade everything, as hotmail had block the IP of our server saying that Spam were going from this IP, this was a big chock for us!

Then this happen again with my voila.fr personal account, see message below.

After having created spam with their own system (hotmail) they are blocking server IPs which they think are copying them !!! (they want to keep their copyright... :)

I wouldn't like to be have an Hotmail account right now, receive no genuine email any more because the master called Ms decided to do so....

I just hope that they fix it soon before I loose my friends :)
