That's from your web host? Who are they? It's very badly written, as if the writer is trying to present himself as an authority but doesn't know all the right words. It doesn't sound professional at all. Are you sure it's legitimate?
Edit: Actually, is it translated from another language? That would explain the grammar and word choice, but not the content of the message. See below.
Even if it is legitimate, you should ask them for more specific information. No decent host would accuse you of doing something wrong but make you figure out exactly what yourself.
