Could it be an issue specifically with Hotmail Italy? Or is it generic to all Hotmail addresses?
I don't know and frankly speaking I don't give enough of a !@#$ anymore. I'm done with hotmail once and for all. From this day onward, bounces from hotmail will be considered a feature and not a bug. I strongly recommend putting the hotmail block back into the registration code and extending it to live.com and outlook.com
