I'm just pointing out that you can't assume that J. Random System out there in the net will be able to accept a path starting with an unqualified host name and route it appropriately. Now if someone at *mysite* is routing like this and gets a bounce from apple.mysite, they can presumably get better routing info from their system admins. But third parties can't assume that. > One way that people get into trouble is with the assumption that host!user > is the same as user@host. This assumption is built into too much software to change. > You already objected to adding ".uucp" on the end of the hostname. user@apple.uucp is as good a way of doing it as anything. The basic problem is that there really is no good way. How do folks out on the internet get mail to uucp sites? Most of the ones I know just punt it to a site that they know does pathalias. How about formalising this behaviour and making uucp a real domain with all these known smart sites as MX? -- Peter da Silva. `-_-' peter@ferranti.com +1 713 274 5180.
