We don't seem to need " :host => Setting[:foreman_url] " on the link_to_host line further up in the file (https://github.com/GregSutcliffe/foreman/blob/639ad9ce4e4bb8da5e9aa0cfab8ac50f267b5b1b/app/views/host_mailer/_active_hosts.html.erb#L19). Why do I need to specify it here? If I just use ":host => host" in the same way, it creates the wrong links....
