It shouldn't make any difference whether the split configuration is used or not for what we are doing. A defaults-accepting installation would use "local delivery only; not on a network". Obviously this would not suit testing mail delivery to other machines on the LAN. It was at this first page I made my mistake! I chose "Internet site......" because that is the way I always send mail. No wonder I got "Unrouteable address". Was it clear that I should have used "mail sent by smarthost......" (Liam?)?. Mystery solved. I've not tested extensively but I can get mail to go to a user on another machine. I'm not enamoured of this technique because it does not suit my mail setup. So I will stick with the more versatile hubbed_hosts. Thanks for all the clues. -- Brian.
