Could anybody point me in the direction of information reguarding converting an Internet address such as: noreiga@jail.usa.gov into a UUCP address like: uunet!jail!noreiga I've read the mailaddr man page but have found little in books/tutorials. Is there a "definitive reference" that discusses how to do the conversion. Sorry if this has been addressed before, I'm new to talking over the net. Thanks in advance.

I don't have time for a long reply (dinner calls!) but the short
answer is, if you can send mail to uunet, mail to
uunet!jail.usa.gov!noreiga should do the trick.

No problem. That's what this newsgroup is for.

Dan is both right and wrong. the "jail.usa.gov" is a domain address.
And, yes, mail routing can be very complex. But depending on the
mailer you use, the example he gives may not work.
I suggest using "<site>!jail.usa.gov!noreiga", where site can be uunet,
but can also be most any other machine that communicates via the internet.
There are two RFC's on mail routing; unfortunately I can't remember the
numbers, but I'd only recommend looking these up if you're *really*
interested in the mechanics of routing algebra's (!'s before .'s and equal
to @'s, etc).
Hope this helps.

Is it saying noriega at |jail.usu.gov, which is a system that uunet.uu.net knows about? The rules say that there can be only one "@" in an address, since it is supposed to be a name and not a route. The "%" was invented as a kluge to add some routing like "!" in UUCP, and is mostly equivalent to "@" in syntax. The problem is that once "%" gets into the UUCP domain, many mailers don't recognize it as a special character - 'smail' is a typical example. An address "you%there@becker.UUCP" is presumably intended to go to UUCP site "becker" who will then figure out "you%there" and send to user "you" at site "there", as if "you@there" had been specified from there. Until quite recently, when I put in a patch to 'smail', such mail would be delivered to local user "you%there" on "becker" - 'smail', finding no such user, would bounce the message. The other problem is that there is no established precedence in operators between "@" and "!". "uunet!bdb@becker" is subject to interpretation as "becker!uunet!bdb" or "uunet!becker!bdb", when moved into the UUCP domain. So in order to address this site you might need to try "becker!bdb@uunet" to get there instead, depending on local or intermediate mailer implementations. For 'smail', the second form turns out to be the correct one. When "%" is interpreted as "@", the same problems arise. They are slightly simpler due to the fact that "%" is not official, so the default behavior of 'smail' above is technically correct, if unforgiving. If "%" is interpreted, it is done last, after all other mistakes are made (if any), so it does have an implied precedence of a sort. This is lotsa fun, but not necessarily productive when you want to get mail from one network to another - "%" can help, but like "!", you end up needing to know local and intermediate conditions in order to use it effectively. I've probably said things which others will have differing opinions on - if so, the ensuing brouhaha will likely be educational, if things are working as they should...

An address of the form <@host1,@host2:person@host3> (where host1/2/3 are in domain form) is legal, although I've found that a lot of mailers will kindly re-write that for you, sometimes into a form that the receiving system won't accept...(i.e. the above might be translated into person%host3%host2@host1, but any of the hosts in the route may not like that format. -- Steve Peltz (almost) CFI-G "Monticello traffic, Glider 949 landing 18, full stop"

While it's now officially frowned upon, the IPP will *not* do you grievous bodily harm if you do it responsibly. Let's suppose you have an address that doesn't resolve--like HAYES.FAI.ALASKA.EDU for example. (nslookup says the only valid *.fai.alaska.edu are acad3, barney, fred, sxclm, sxjlh, sxtjh, systems, systems1, ua-gw, and ua-gw2.) I might try @acad3.fai.alaska.edu:wisner@hayes.fai.alaska.edu in the hope that acad3 runs a hacked mail system that intercepts what appears to be a bogus address. And yes, there's more than one @ in there. (Bill, why do your articles look like NNTP forgeries?) -=EPS=-

Yeah, but they *should* do you harm. How can you be sure that the sites
that will route your mail will be hacked appropriately.
To get mail to Bill without attracting the attention of the IPP, mail to:
acad3.fai.alaska.edu!hayes.fai.alaska.edu!wisner
(sending directly to hayes would probably work, as nslookup may not be
completely up to date. it would get to fai, and locally get sent to
the proper place.)
Both RFC's (at least the latest one) say that you can use full domain names
as intermediate routers. You need never use an @ sign again, actually.
This is probably the preferred method for people who live on UUCP nodes,
and don't have nslookup.

Sorry, that's not how it works. If nslookup can't find it, nothing else has a prayer. Messages do not get sent to fai first (though fai.alaska.edu happens to be valid, there's no no "requirement" for a host to "be its domain"). In any case, I received mail from Bill saying that (1) the DNS information for his machine is screwed up, and he's been trying to get the appropriate administrators to fix this and (2) please not to use acad3 as a relay because it is screwed up even more. What he didn't send me was a domain literal, which could work around the lack of name service. I trust that the problems are being attended to. -=EPS=-
