Somebody could (did) register ac.uk with the owner of the uk zone. Somebody (else) registered cam.ac.uk with the owner of the ac.uk zone. I think you may need to understand the concept of DNS zones. That's about the nearest concept that seems to be what you are trying to do. But even that won't help. As has been said, for cus.cam.ac.uk do you want cam.ac.uk or ac.uk? Both exist as separate DNS zones. If we make it abstract, when you see x.y.z.example do you want z.example or y.z.example? You can't tell just by looking at it. -- Philip Hazel University of Cambridge Computing Service Get the Exim 4 book: http://www.uit.co.uk/exim-book -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
