This means that you have a DNS problem for tmp_site.com, because the
remote server is complaining that the DNS for the _sender_ does not
exist.

So the problem isn't with your Apache or Exim set-up, but with the DNS
provisioning. You probably can't band-aid this in your Exim set-up,
since it's remote sites complaining about the DNS published data,
insisting that any mail-domain used in a sender address actually exists
and can be used for sending mail back to.
