First of all, let me point out that the title (and content of this article) does not read out “GMX is evil”. I like GMX, but imho they made a mistake in enabling @gmx.net as a possible domain part in their free email service.
GMX (short for Global Message eXchange) was founded as a German company and is now owned by United Internet. The most popular service back in the days (and maybe still today) was their freemail service.
