Sendmail error

uadm26 — Tue, 21 Jun 2005 09:05:53 GMT

Hi,

That's the first time that I try to send a mail in this machine whith hp-ux 11i, and reports that error:

serverrp:/tmp/joel# cat joel | sendmail -v 89874@fidelidade.pt
fidelidade.pt: Name server timeout
89874@fidelidade.pt... Transient parse error -- message queued for future delivery
89874@fidelidade.pt... queued

I have the entry in /etc/hosts

172.xx.xx.xx fidelidade.pt

telnet fidelidade by port 25, it's fine

There's something wrong, any ideias?

Hi Joel,

Sounds like a DNS problem. Run nslookup with no argument and set the server for your DNS server (get it from /etc/resolv.conf)

#nslookup
> server 111.222.111.222
>set type=MX
>fidelidade.pt

fidelidade.pt preference = 10, mail exchanger = mail.fidelidade.pt
Authoritative answers can be found from:
fidelidade.pt nameserver = ns2.ip.pt
fidelidade.pt nameserver = ns.ip.pt
mail.fidelidade.pt internet address = 194.79.65.149
ns.ip.pt internet address = 194.79.69.129
ns2.ip.pt internet address = 194.79.69.131

So either your internal DNS is not retrieving the MX record for fidelidade.pt or you're not getting to your internal smart relay system which should look that up. Sendmail will *not* send mail unless it can resolve the DNS MX record for the destination.

HTH,
Jeff

Hi,

But i don't have a DNS server configured.
nslookup uses the /etc/hosts.

Check the /etc/nsswitch.conf file to make sure you are looking at /etc/hosts file for lookups.

please check router configuration, it can also be caused by invalid/non-existing router information.

also check /etc/resolv.conf (i am not sure of the path) which lists the name servers, ensure you do not have any non-working name servers listed there.

Hope this helps,
Gopi
