I thought I'd post to this long dead thread, as I spent a good hour trying to (unsuccessfully) find a solution online. In exim4.conf.template there is a line ignore_target_hosts which contains the list of private network ranges. If your MX record points to an address on this list then delivery fails with the above error, even if the DNS is otherwise fine (which it is, if this is an internal DNS setup.) I removed our subnet from that list, restarted Exim and it all worked fine. Not sure if there is a better way to do this. Hope this helps someone, -- George Borisov DXSolutions Ltd
