I can send mail from killer to uunet!epimass.epi.com!jbuck and Joe will get it. killer doesn't know uunet, but the mailer will find a route there. This is an address, not a route. To further illustrate the point, classify the following as route or address. jbuck%epimass.epi.com@uunet.uu.net @uunet.uu.net:jbuck@epimass.epi.com ..b

] Killer has no link to uunet, and uunet!epimass.epi.com!jbuck works so ] u!e!j must be an address. Nope. The agent that created that address is telling killer give this to uunet, with info so uunet will give it to jbuck. Your machine is smart enough to know how to get there, but there is no requirement that all machine be so smart. Is cca!pineapple!rsalz a route or an address? It's an address, because it all depends on where you're coming from. To most folks "cca" will be cca.cca.com; however we have a bbn.cca.com ... If there is more than one ! in a path, it's a route. If it were an address, then people would not be getting upset at Rutgers for modifying them, right? >classify the following as route or address. >jbuck%epimass.epi.com@uunet.uu.net This is an address of the form "local-part@uunet.uu.net" the "%" hack is nowhere defined. Also, you're confusing things because epimass has a direct uunet link. Is "rs%mirror.uucp@harvard.harvard.edu" a route or an address? There never was a mirror<->harvard UUCP link. (The question's rhetorical: it's an address.) >@uunet.uu.net:jbuck@epimass.epi.com This is an RFC822 route. /r$ -- Please send comp.sources.unix-related mail to rsalz@uunet.uu.net.

Such mail will actually go from uunet to wrl.epi.com and then to us, or take a completely different route depending on what's in the map data. epimass does not talk directly to uunet. I give that address so people with obsolete Internet mailers that don't understand MX records (and there are a hell of a lot of them) can mail to me. Since MX records for .epi.com point to uunet.uu.net, it's really equivalent to jbuck@epimass.epi.com for those purposes. -- - Joe Buck {uunet,ucbvax,sun,<smart-site>}!epimass.epi.com!jbuck Old Internet mailers: jbuck%epimass.epi.com@uunet.uu.net

Joe:
classify the following as route or address.
jbuck%epimass.epi.com@uunet.uu.net
Me:
This is an address of the form "local-part@uunet.uu.net" the "%" hack is
nowhere defined. Also, you're confusing things because epimass has
a direct uunet link.
Joe:
Nope. Such mail will actually go from uunet to wrl.epi.com and then
to us, or take a completely different route depending on what's in
the map data. epimass does not talk directly to uunet.
Okay, so I had the right answer for the wrong reason: it's an address
because it does *not* specify any routing information...
