Hi,

your DNS seems to return "tesofe.gob.mx" as the MX (=mail exchanger) for your station!
Modify the "MX" record in the DNS server's data files.

HTH,

Hi
in your /etc/hosts
on lucus / patito.com
put an entry in for the server that you are trying to send email from.
try to send email in this command syntax.

echo test | sendmail -v ssarmiento@patito.com

and post what you see.

Thanks

I`m here again

I did:

echo test | sendmail -v
ssarmiento@patito.com

ssarmiento@patito.com... patito.com: Name server timeout
ssarmiento@patito.com... Transient parse error -- message queued for future delivery
ssarmiento@patito.com... queued

I think that the problem is DNS but I put the name in hosts.

Thanks

hi ssarmiento
Lets see here

are you trying to send to the server its self?

or are you trying to send from another server to
patito.com?

are you trying to send all local or going through the internet?

what are your results from
nslookup patito.com

is patito.com is the same as lucus? what if you do
sendmail -v ssarmiento@lucus

Let me know

Bill Hassell — Tue, 28 May 2002 21:50:44 GMT

nslookup must be able to resolve the name for the mail relay. If nslookup fails to find an IP address, and the name is in /etc/hosts, then your nameserver switch file is incorrect. Change it to look in /etc/hosts first by editing /etc/nsswitch.conf:

hosts: files[NOTFOUND=continue UNAVAIL=continue] dns [NOTFOUND=return UNAVAIL=continue TRYAGAIN=return]

The above is all 1 line in the file.

hi,

R..are you trying to send to the server its self?

SS..yes, the server will be local and internet

R..or are you trying to send from another server to
patito.com?

SS.. The server is loner

R..are you trying to send all local or going through the internet?

SS.. Will be both, but now is local only, this server will replace the currenty

R..what are your results from
nslookup patito.com

SS.. I don`t have DNS, the resolve is for file (/etc/hosts)

R.. is patito.com is the same as lucus?

SS.. Lucas is the server name and patito.com is alias in the /etc/hosts

R..what if you do
sendmail -v ssarmiento@lucus

SS..sendmail -v ssarmiento@lucas
ssarmiento@lucas... lucas: Name server timeout
ssarmiento@lucas... Transient parse error -- message queued for future delivery

I hope you understand me

Re: Sendmail

ssarmiento — Tue, 28 May 2002 22:12:04 GMT

Ok.

I did:

[root@lucas #] nslookup
Using /etc/hosts on: lucas

> patito.com
Using /etc/hosts on: lucas

looking up FILES
Name: lucas
Address: 10.10.10.10
Aliases: patito.com

Hey friends,

The problem was in /etc/nsswitch.conf as said Bill Hassell.

but I know that Richard will reach the solution.

Thanks

Great I am glad you found the problem. But I am still troubled to what fixed your issues.

Mr. Bill Hasselss : I agree that in /etc/nsswitch.conf you have to specify where you are going to resolv from.

But ss specified that he was not using dns. And was only using /etc/hosts to resolv hostnames.

his /etc/nsswitch.conf was

hosts: files dns

If he doesnt have dns set up at all it shouldnt matter what is in nsswitch.conf since it will fail if it looks at dns anyways.

I had to tried this for my self. I took draco and lupus.
on lupus in nsswitch.conf I had:

hosts: files [NOTFOUND=continue UNAVAIL=continue TRYAGAIN=continue] dns

and I was able to send to hercules.

I changed to

files dns

and it still worked.
and even

hosts: files

worked to send mail to the other host.There is no Dns going so i am doing this all though hosts.

my nslookup always gave me:

Using /etc/hosts on: lupus

looking up FILES
Name: draco
Address: 192.168.10.16

So I dont understand why the nsswitch.conf would fix the issue by adding the line to look at dns. Unless I totaly missed something =(

SS:
Did you change anything else?
