Seth,

If you'll read the notice, you'll see that it's because the mail is 
coming from your machine, which is in a block of dynamically allocated 
addresses.  The solution is to configure the server to forward all 
non-local mail to your network provider's e-mail server. In sendmail 
speak this was called a smart host, but your server may have a different 
name for it.

The solution I have used is to configure my applications that send mail 
(including user mail clients) to send via my network provider's smtp 
server. If you need applications to send mail, I have C++ source code 
that will do the trick.
