[lug] Email spam

[Justin]

I have been getting spam email in my www mailbox on my server for quite 
a while now. I have the from header being rejected by the mail server 
but I'm still getting messages in the www box. I don't know if 
something is configured wrong with my mail server or what is allowing 
someone to still do something like this. The emails come daily and are 
always exactly the same thing. Below is the actuall text for the email 
box from /var/spool/mail/www:

Whatup, foo.  Somebody said something about your site.

I'm not sure why the bounce message comes first? 

And here is what was in my /var/log/maillog for the same time frame:

I have a feeling something is not right with my mail server. I'm 
running Postfix and other than this everything is fine. Can anyone shed 
some light on this? TIA.
