I don't know what software you're using to handle mail on your
mail server (you didn't specify the machine in question, so I can't
check from here, either), but you may find that if you have simply
installed the software as shipped that it allows relaying. How to
fix that depends on what software you're using, what functions you
actually need it to serve, and so on.
I'd advise subscribing to spam-l (via mail to [EMAIL PROTECTED])
and visiting http://spam.abuse.net to get more information and to get
help locking up your server. Based on previous experience, once spammers
discover open servers, they tend to swarm to them, so you can expect
further abuse unless you take steps to prevent it.
