Well, it's very common for ratware to do that, but you would have to try hard
to make Exim do it (OK, it's not that hard, but it's nothing you do by
mistake). And nothing in Exim's configuration stops other programs from
sending mail directly with SMTP - to stop that you need a firewall setup. It
seems possible that your server has been cracked, especially since it's a web
server.
