Due to the potential for namespace clashes, you *must* have a single central organisation to manage the localpart namespace. MX records can also only route mail on a domain basis, and not by localpart. Again, this tends to drive centralisation. [...]
Has anyone got any other ideas on how to skin this cat with a technological solution not mentioned?
I would probably be tempted to just contract the whole lot out to a third party that is not involved in your internal politics, including maintaining a localpart registry. The third party can then make a commercial decision as to the best way to design the network is an complicated geographically load-balanced cluster, or just to waste bandwidth and take a simpler system. Unless they've got somebody CV-polishing, KISS will probably prevail as bandwidth is cheap. -- PGP key ID E85DC776 - finger abuse@mooli.org.uk for full key Please contribute to the beer fund and a tidier house: http://search.ebay.co.uk/_W0QQfgtpZ1QQfrppZ25QQsassZpndc
