there are ways around this. Depends on your MTA - I can only speak for 
sendmail. If you use sendmail you can try milter-null, I found it works 
great, you'll need to install it on your outbound as well as your 
inbound and share the "secret" between them.

I believe postfix can also use sendmail milters but postfix may have its 
own solution too.

If you're using Exchange outbound then you're probably out of luck!
