Email addresses in Belgium?

Here are the best sites that offer free email addresses. If you have an address like name@isp.fr - good for you, but what happens if you change your internet provider? Yes, everyone you gave that address to will no longer be able to write to you. Plus, it’s always handy to have an extra email address - one that you use for work and/or friends and another that you give on websites that require registration before use - sometimes these sites are not very reliable when it comes to "selling email addresses"... you quickly find yourself with an inbox full of spam. That's the advantage of a free email address... if you receive too much spam on it, you just delete it and create a new one. Below are our best offers.

First of all, thanks to bloodyangel for her reply, but actually the Belgian contact is my sister and she does have her address on Skynet, but she tells me that her emails go through Outlook. However, for some time she hasn't been able to send me photos and she doesn't want to use Hotmail, so I was wondering if there is a way to send her emails through another server? Thank you for the information.
