I have an exim server configured to send non-local mail through a remote smarthost and it is working fine in that capacity. Now, I am setting up a dev mail server for testing an advanced groupware application. I need to send mail to this server, but it does not have a valid DNS name on the internet, nor is it accessible from the internet. Now I've created a hostname for it on our local LAN DNS, but since exim just sees this as any other non-local domain name, it tries to route it through the smarthost, which rejects it. So, is there a way I can configure Exim to route mail to one specific domain through a specific host?

Running Exim4 on Debian Etch.
