I have received mail many times and sometimes I do a "r" for reply while in mail, I get the mail back. It got to me, why can't I send the other way? On a simular note, I received a message in mail and saved it for later. When I read it, it had different names for that person. (I tried them all and only got back the message saying it can't be delivered. Can anyone tell me how to decifer these? Like "someplace!somehow! guy@uunet.uu.net" or "ad897963-dads3@somewhere.here"? -- Guy Dandrea, Network Systems Corp. // guy@nsco.network.com #129.191.1.1 \\ // 7600 Boone Ave No, Mpls.

It got to me, why can't I send the other way? This obviously isn't the correct newsgroup for your question since the amiga doesn't have a mail utility, but I'll give you a quicky answer that may get you started. One of the problems with large inter-connected networks is that it quite easy to get mail going out; you don't have to be properly registered in the various domains to make this happen, hence you can NOT trust the return address. The return may be bogus, may be valid, may be fraudulent, or may have gone some through some form of "poor man's" gateways. If both you and the are properly registered in the same network (eg Internet, Netnorth, etc), then you usually don't have a problem. > Can anyone tell me how to decifer these? > Like "someplace!somehow! guy@uunet.uu.net" or "ad897963-dads3@somewhere.here"? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This addressing method is likely to get you in trouble in many mailers... > -- > Guy Dandrea, Network Systems Corp. // > guy@nsco.network.com #129.191.1.1 \\ // > 7600 Boone Ave No, Mpls.

It got to me, why can't I send the other way? You are probably using Berkeley mail on an Unix system. Your problem is that the computer is not always smart enough to figure out the proper address of the person who sent you the mail. When someone sends you mail, he doesn't always send his complete address, so the mail system has to try to turn the address around. For various assorted reasons, it often screws up, especially if the message has to go through several "hops" before it gets to its destination. >On a simular note, I received a message in mail and saved it for later. When >I read it, it had different names for that person. (I tried them all and only >got back the message saying it can't be delivered. Very often, there is more than one way to get mail to some destination. >Can anyone tell me how to decifer these? >Like "someplace!somehow! guy@uunet.uu.net" or "ad897963-dads3@somewhere.here"? Well, I don't want to give you a complete tutorial on this. Go look in alt.sys.amiga.uucp for Matt Dillon's posting that explains lots of stuff about how to address mail. If you can't find it, ask someone to post it. Also, ask around your local area for people that send a lot of mail. They will know how to do it. someplace!somehow!guy@uunet.uu.net Send the mail through the Internet to a very popular machine named uunet.uu.net. Uunet will send it through some combination of machines to a machine named "someplace." Someplace will connect directly through uucp (probably a modem call) to a machine named "somehow," then somehow will deliver the mail to a user named guy. ad897963-dads@somewhere.here Send mail (probably through the internet) to some machine named "somewhere" which is in the "here" domain. That machine will deliver the mail to a user cursed with the username "ad897963-dads." If mail comes back to you, that is called a "bounce." It means there was some problem in delivering it, usually a reference to an unknown machine (host). In this case, look at the "Received:" lines in the original message to you to determine what path the incoming message took. Based on this, it is possible to reverse the path and send the mail the other way (usually). Ask someone at your site to demonstrate this to you. Of course, the mail networks are so large and complicated, there are regularly problems with them. Sometimes, it just plain isn't possible to send mail to someone, due to faults. Sometimes, it's just too complex to figure out, often when you see a Usenet post with a .UUCP in the mail address. This is why people should attatch signatures to their posts giving a good email address with the name of a fully domained (dots in the name) site in it.

I refer, of course, to Matt Dillon's UUCP system, complete with UUCP, Netnews, _AND_ mail. Works fine, lasts a long time. >> Can anyone tell me how to decifer these? >> Like "someplace!somehow! guy@uunet.uu.net" or "ad897963-dads3@somewhere.here"? > ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ > This addressing method is likely to get you in trouble in many mailers... Yes, it can. I'll explain. A path (address) containing "!" characters (we call them "bangs") describes a path from system to system that is used by the uucp (Unix-to-Unix-CoPy) program. The first path above says that the message, somehow must get to "someplace" then to "somehow" and from there it goes to uunet.uu.net and into the mailbox of some user named "guy". This path is called "mixed mode", since it uses the bang path and an Internet-style domain. Most mailing programs have major problems using mixed mode addresses. The second path above is merely an Internet-style domain address. It assumes that your software knows how to send a message to "somewhere.here" (it looks it up in a map database and builds a bang path to get it from point A to point B, but you never see that happen. It's "magic".) Once it gets to "somewhere.here", it goes into the mailbox of user "ad897963-dads3" on that system. If you look at my .signature below, you'll see two different addresses, one for the system here at the office (tmiuv0!rick) and one for the Unix box (and eventually my A3000, that is the xyclone!sysop address). The first line of the address is the uucp bang path, which assumes that you know how to get a message to the system "uunet". The second line has the equivalent Internet domain address. This really belongs in the comp.mail group. But, you knew that already. > >> -- >> Guy Dandrea, Network Systems Corp. // >> guy@nsco.network.com #129.191.1.1 \\ // >> 7600 Boone Ave No, Mpls.
