- sendmail help needed
- ---------------------
-
- Can some kind soul out there please help with a sendmail query?
- Please forgive if this is a FAQ, but I have no access to anonymous
- ftp here, and so can't access FAQ lists or any of the useful tools
- which float around.
-
- We have a NeXT network which uses a mail server (server) and a
- machine connected to a modem (techw1). It is not geographically
- convenient to make techw1 the mail server, or to connect the modem
- to server (which would solve a lot of our problems).
-
- We have recently acquired a feed to the Internet Mail, which in
- theory, should allow us to send and receive mail from and to any
- machine on the network.
-
- The system at present is set up so that a TCP uucp link is set up
- between techw1 and server so that server polls techw1 every 5
- minutes or so (hardly elegant, but it works). techw1 has a modem
- uucp link set up to a VAXlet which is set up as a gateway to the
- Internet. I have hacked techw1's sendmail.cf (which I copied
- from sendmail.cf.mailhost) so that
-
- DM uucp
-
- DR twics
- CR twics
-
- (twics being the name of the VAXlet which is acting as the
- gateway). I have also followed the Ruleset 0 decomment and
- comment instructions.
-
- On server, I have set
-
- DM uucp
-
- DR techw1
- DR techw1
-
- and hacked Ruleset 0.
- When sending a message from techw1 to foo@bar.com, this goes
- straight into the uucp queue and on a uucico call to twics, it gets
- delivered to twics (what happens after that, I don't know - I
- suspect a black hole in the immediate vicinity, but that's not
- *my* immediate problem!).
-
- When sending a message from server to foo@bar.com, the message
- gets placed in the uucp spool queue. On the next
- crontab-generated poll it gets passed to techw1, which sticks it
- in the twics uucp spool queue, and it goes out into the big wide
- world.
-
- However, if I send from a client of server, the mail bounces with:
-
- > ----- Transcript of session follows ----- 421 Host
- > crestec.twics.co.jp not found for mailer ddn. 550
- > <hashton@crestec.twics.co.jp>... Host unknown
- >
- > ----- Unsent message follows ----- Return-Path: <hashton>
- > Received: from techw3 (techw3) by server (NeXT-1.0 (From
- > Sendmail 5.52)/NeXT-2.0) id AA06068; Thu, 20 Aug 92 08:56:47
- > JST Message-Id: <9208192356.AA06068@ server >
- >
-
- Examining /usr/spool/mqueue/syslog on server, I discover that
- if I send a message from server or techw1, the syslog contains:
-
- Aug 20 08:55:22 server sendmail[6060]: AA06060:
- to=hashton@crestec.twics.co.jp, delay=00:00:01, stat=Sent
-
- and if I send from a client, I get the following in the syslog:
-
- Aug 20 08:56:48 server sendmail[6070]: AA06068:
- to=<hashton@crestec.twics.co.jp>, delay=00:00:01,
- stat=Host unknown
-
- Somehow, somewhere, the address is being parsed as
- <foo@bar.com> from a client and is not parsed this way from server
- or techw1. I thought (in my innocence) that setting a relay to uucp
- on server would parse any unknown domains correctly. No way. btw,
- when an address goes out from techw1, it's parsed as:
-
- hashton twics (8/20-13:03-2657) XQT QUE'D (rmail bar.com!foo)
-
- This comes from /usr/spool/uucp/LOGFILE. Seems OK to me (but
- then, I'm stupid).
-
- I have also clobbered techw1's local mail in the process. I used to
- be able to send to fred (all users are networkwide), but I now have
- to send to fred@server (I lose user pictures, aliases, etc.,
- because I now appear to live in a different domain). If I try
- sending to fred, I get:
- > techw1:38# mail -v fred
- > Subject: Test
- > Clobbered
- > .
- > EOT
- > fred... Connecting to (local)...
- > mail: /usr/spool/mail/fred: cannot append
- > mail: cannot open dead.letter
- > fred... 554 unknown mailer error 1
- > Saving message in //dead.letter
- > //dead.letter... Sent
- >
- >
- This is a minor hassle by comparison with the problem of clients
- being unable to deliver outside their domain.
-
- I have tried to RTFM and the O'Reilly/Todino book. I don't claim to
- understand it all, but pointers to the relevant places in
- documentation would be valuable.
-
- My e-mail address is now officially:
- hashton@crestec.twics.co.jp
-
- Mail addressed to my old address:
- hashton@twics.co.jp
-
- _should_ be forwarded. If it bounces:
-
