sendmail: host name lookup failure

sendmail: host name lookup failure

Post by h.. » Tue, 25 Mar 1997 04:00:00



I am trying to configure sendmail on "abc" to send all mail
except local mail to be forwarded to "def" which will forward
it to the rest of the world.  I keep getting a
"host name lookup failure" message although local mail on "abc"
works fine.  Mail from "ghi" and "jkl" using "zmail" also gets
out nicely.  Any help would be greatly appreciated.

The configuration:

----------------------ethernet 10baseT----------------
    |             |             |             |
    |             |             |             |
    |             |             |             |
---------     ---------     ---------     ---------
|  abc  |     |  def  |     |  ghi  |     |  jkl  |
---------     ---------     ---------     ---------
                  |
                  |----> to the outside world and to other local networks

"abc" is an SCO box, rel 5.0.2
"def" is a router
"ghi" and "jkl" are WIN 95 boxes

"mailq" returns the following:

                Mail Queue (1 request)
--Q-ID-- --Size-- -----Q-Time----- ------------Sender/Recipient------------

1. sendmail - host name lookup failure

Hi,

i use OpenServer5.0.5 with sendmail 8.8.8 without DNS!
I've read the SCO TA 107682 and TA 107669, then
i've configured in my sendmail.cf the line

DDbundy.de
O ServiceSwitchFile=/etc/service.switch
OI-DNSRCH

/etc/service.switch
hosts files

/etc/hosts
xx.xx.xx.xx    mail mail.bundy.de

but i get the error message:
Name server: mail.bundy.de.: host name lookup failure

Why? Then i've used the version 8.8.5 and i got the same.

/var/adm/syslog

ctladdr=root (0/3), delay=00:00:00, xdelay=00:00:00, mailer=smtp,
relay=mail.bundy.de. [200.0.0.98],
stat=Deferred: Name server: mail.bundy.de.: host name lookup failure

Thank a lot for the help and best regards
