-
- This error is not being produced by PMDF. It is being produced by the remote
- machine after PMDF successfully transfers mail to it. The Received: header
-
- Received: from chemna.dichi.unina.it by risc55.dichi.unina.it (AIX 3.1/UCB 5.61/4.03)
- id AA03814; Wed, 2 Sep 92 15:09:13 -0500
-
- clearly indicates that the message has been transferred. Once the message is
- transferred PMDF no longer has responsibility for it. This is therefore
- definitely NOT a PMDF problem.
-
- The error messages
-
- >>> HELO risc55.dichi.unina.it
- <<< 553 Local configuration error, hostname not recognized as local
- 554 <avitab@[192.135.165.26]>... Service unavailable: Bad file number
-
- indicate that sendmail on risc55.dichi.unina.it is misconfigured. It
- apparently does not know its own IP address.
-
- I am not sure why you are trying to send to the machine's IP address anyway.
- sendmail is notorious for not supporting this sort of thing correctly.
- You might want to change the rules:
-
- risc55.dichi.unina.it $U%$D@mtcp-daemon
- [192.135.165.26] $U%$D@mtcp-daemon
-
- to read:
-
- risc55.dichi.unina.it $U%risc55.dichi.unina.it@mtcp-daemon
- [192.135.165.26] $U%risc55.dichi.unina.it@mtcp-daemon
-
- This will avoid the use of the IP address that sendmail cannot handle.
-
- I note, however, that the DNS is incorrectly configured for this machine. There
- is no A record pointing risc55.dichi.unina.it to [192.135.165.26] and there is
- no PTR record pointing [192.135.165.26] to risc55.dichi.unina.it. The machine
- is in fact on the Internet and reachable at its IP address. The lack of this
- information may actually be what's confusing sendmail.
-
- > My machine is chemna.dichi.unina.it running VMS 5.5, PMDF 4.0
- > and Multinet 3.1.
-
- Your machine is also not registered in the DNS. You do have an MX record, but
- MX records are no substitute for correct DNS information. Correct DNS
- information should be provided for all systems that are directly connected
- to the Internet.

- > An example of delivery failure follows. I mailed a message to

- > mail, stating the failure.
-
- I beg to differ. The mail was sent to avitab@[192.135.165.26], not
- avitab@risc55.dichi.unina.it. Use of avitab@[192.135.165.26] is in fact
- working insofar as reaching the remote host goes, but the remote host is then
- failing to deliver the mail properly. This is not a PMDF problem.
-
- > 1) Failures like this one happen with any destination
-
- I quite frankly don't believe this is true either. In any event the example you
- provide does not demonstrate that such problems exist.
-
- > 2) The RISC6000 machine is able to receive mail by SMTP at the
- > same address I used, coming from other hosts
-
- This is also incorrect. I sent mail not using PMDF to this system using its IP
- address and had similar problems with it. This simply confirms that the IBM
- system is not properly configured.
-
- > I enclose my PMDF.CNF file. Any help will be appreciated.
-
- There is nothing wrong with your configuration that I can see. You can
- make the change indicated above and it may serve to work around the
- problems with domain literals. However, the fact that the DNS doesn't know
- about risc55.dichi.unina.it may then prevent delivery. (You may have host
- tables that work around this problem -- I would not know about that.) But this
- is a DNS issue and not a PMDF issue.
