Message-ID: <1990Oct13.171252.16410@elroy.jpl.nasa.gov> Date: 13 Oct 90 17:12:52 GMT Sender: news@elroy.jpl.nasa.gov (Usenet) Organization: Jet Propulsion Laboratory, Pasadena, CA Lines: 61 Originator: gwalsh@kilroy Nntp-Posting-Host: kilroy.jpl.nasa.gov We recently purchased 3 NeXT computer systems and have been having trouble getting the mail system to receive mail properly. I'm the System Administrator for our Sun SparcStation 1+ machines so the people that got the NeXT machines asked me for help. I started by configuring their 'sendmail.cf' file to basically match the same configuration as that on the Suns. First of all, I noticed that the sendmail.cf file is in the /etc/sendmail directory and not in the /etc directory like the Sun. To be safe, I put a copy of sendmail.cf in both directories. Our machines are configured to use the nameserver as a mail relay too. We started out by sending mail from the NeXT to one of the Sun machines. This worked out fine, but it appears that the NeXT sent it directly, rather than going through the mail relay, since there was no extra header from the mail relay in the received message. For the next test, we sent mail from the sun to the NeXT using the '-v' (verbose) mode option in mail. This allowed us to watch the connection for problems. We saw none.. the mail went off just fine! Within a minute or two, I got a message from the Mailer Daemon on the Sun telling me that the message did not make it. Here is an excerpt from that message: ----- Transcript of session follows ----- Connected to talia.jpl.nasa.gov: >>> HELO talia.Jpl.Nasa.Gov <<< 553 talia.Jpl.Nasa.Gov host name configuration error 554 ... Service unavailable The next thing I tried was to telnet to port 25 on the NeXT and go through the process of sending mail manually. I did the HELO and told it I was kilroy.jpl.nasa.gov and I all the other things involved in sending mail (MAIL, RCPT, DATA, QUIT). All of these worked fine, so it appears that the NeXT is doing something with the mail after that and then generating the returned mail. The next thing I did was telnet to port 25 again, but this time, rather than telling it I was kilroy with mail (ie): $ telnet talia 25 HELO kilroy.jpl.nasa.gov I did this: $ telnet talia 25 HELO talia.jpl.nasa.gov In this way, I was telling the mail program on talia that I WAS the machine talia with mail. At this point, the machine gave me the same output as it did when it bounced the mail back: <<< 553 talia.Jpl.Nasa.Gov host name configuration error My only conclusion at this point is that once the NeXT accepts the incoming email that it telnet's to its own port 25 to send it to itself again and then it croaks! Anyone got any ideas what I'm doing wrong?? Gerald J.
