If you have an email ending in @hotmail.com, @live.com or @outlook.com (or any other Microsoft-related domain), please consider changing it to another email provider; Microsoft decided to instantly block the server's IP, so emails can't be sent to these addresses.
If you use an @yahoo.com email or any related Yahoo services, they have blocked us also due to "user complaints"
