I don't think I need the user to be rejected. I need sendmail to not 
even try to deliver locally.  It feels like this is what is happening:

A web form on www.mydomain.com generates an email for someone at mydomain.com
PHP calls sendmail on the local box
sendmail looks in its config to see if it is supposed to handle mail for 
mydomain.com
if it is it delivers the mail locally
if it is not it does a dns call to find the mx record for mydomain.com 
and sends the mail to that ipaddress

It is the latter that I need to have happen. 
I want mail to be sent to mydomain.com users just not on this box.  It 
sounds like I can get close by removing the entries in local-host-names 
and restarting sendmail.

Where are the records stored for the email aliases for the sites so I 
can at least remove them programatically.
Does anyone know?

Thanks for the response,

Bret
