I have a number of undelivered messages in the mailqueue. The mailqueue
reports: Deferred: Name server: yahoo.com.: host name lookup failure. I
attempted to send these emails from a remote client (Outlook Express) and
cannot understand why the domain name can't be discovered.
nslookup yahoo.com.
Server: 210.55.12.1
Address: 210.55.12.1#53
Non-authoritative answer:
Name: yahoo.com
Address: 66.94.234.13
echo test | sendmail -v user at yahoo.com
<snip>
250 2.0.0 <.ID.> Message accepted for delivery
</snip>
/etc/resolv.conf:
nameserver 210.55.12.1
/etc/hosts
127.0.0.1 servername localhost.localdomain localhost
Don't know if the following is relevant
service nscd status
nscd is stopped
Any help would be appreciated.
Regards
Cameron
