Sendmail by default does not relay, unless you enable PROMICUOUS_RELAY. To test if you have an open relay, go to: http://www.abuse.net/relay.html and run a test against your server. It may be a "rumplestinkin attack", the spammers are trying to guess account names in your server, postmaster gets a copy of the bounce. Look at the logs for the full info.
