i found out how to do it manually eventually
step 1. ( joe.doe.com = your server ) telnet your server on the smtp port ( 25 ) to open a connection
telnet joe.doe.com 25
step 2. identify your self ( my.addr is your boxes ip address )
helo my.addr
step 3. tell the server who the message if from
mail from:spammer@badhost.com
step4. tell your server who the message is going to ( final destination )
rcpt to:tobespammed@targetuser.com
at this point it will either say:
ok... will forward ( or something to that effect ) - this is bad your mail server is an open relay, you need to fix it ASAP
relaying not allowed ( or something to that effect ) - this is good your attempted message has been blocked and your server is not an open relay
it may be best to test this from outside your network because some mail servers are setup to relay everything from inside its local network
