do a google search for mail relay test. it is on abuse.net

it will do a ton of tests for a given host to find out if it is a open
relay.

tim,

this could be someone outside your network trying to use your mail server as
a
relay. be sure that your FreeBSD server isn't an open sendmail relay as
someone
could effectively clog up your server with relay jink mail and/or spam

Hope this helps
