The first route would send to siteA, then |siteB, then siteC and siteC would route to user@domain.dom which they |would know how to do since they know how to resolve domain addresses |(you hope:-). The second would attempt to send to domain.dom, then to |siteA, then to siteB, then to site C, then to user. This is because the |"@" syntax takes precedence over the "!" syntax. Who says? I don't think any of the RFC's mention ! syntax at all. If your site is a smart site, running sendmail or smail, then @ will usually have precedence over !. but UUCP-only sites only understand !'s, and only look for !'s. To answer Leslie's question in the first place - inews will change siteA!siteB!siteC!user@domain.dom to ..siteC!domain.dom!user, to get around this exact problem... it changes the address to all !'s, if it needs to. | |> SiteA is your uucp neighbor which |> you would obviously know about.

I'm not sure what you mean by |"uucp style forwarding", do you mean versus being directly on the internet? |If so, I would assume that they would also be able to handle that syntax. What (I think) Leslie means is, are all the sites on the way going to handle this address the same way I expect them to (I.E. will they all send to the next host on the bangpath, or will one of them see the @ and send to domain.dom??) -- Bitnet: wcf@psuhcx.bitnet Bill Fenner | "Ain't got no cash, Internet: wcf@hcx.psu.edu | Ain't got no style UUCP: {gatech,rutgers}!psuvax1!psuhcx!wcf | Ain't got no girls Fido: Sysop at 263/42 (814/238 9633) \hogbbs!wcf| To make me smile"
