Edit your sendmail configuration file

vi /etc/mail/sendmail.cf

find the line starting with letters

DS

get the name of your organization's email relay server. Lets say it is exchange.tamco.com.my. Then change this line as follows:

DSexchange.tamco.com.my

if there is no such line, create one like this one above

save the file and exit

talk to the email server administrators and tell them to allow your machine (give them the server name and ip address) to relay mail to outside.

That should do it

You must see mail.log file to determine what what do happen when you send mail.

/var/adm/syslog/mail.log

mail.log give you some information.
For example, you can see:

Jul 9 12:06:16...from=...
Jul 9 12:06:16...to=...relay=...stat=Sent...Queued mail for delivery

mail.log have error messages as well.

Follow Mel's steps

then stop and start the sendmail
/sbin/init.d/sendmail stop
/sbin/init.d/sendmail start

[Andrey Chipalyuk]

Check your DNS and network settings, available of your mail exchanger server.
For example, you can get address of your mail exchanger server for the next way:

nslookup -type=MX your.domain.name

P.S. Don't forget to set points for reply of your questions.

I still not able to send mail from my unix box after add my mail relay server to the DS.

DS

but still not able to send.

thanks

[Mel Burslan]

please post the output from this command

echo test | sendmail -v alson.ng@tamco.com.my

[Steven E. Protter]

Shalom,

Your server is not being permitted to relay mail to the server specified with the DS parameter.

You can test this:

telnet servername 25

If you denied access the relay server must be configured to permit relay.

I have tried the below commnand in Unix

1. nslookup -type=MX your.domain.name

Using /etc/hosts on: tamcoapp

looking up FILES
*** No address information is available for "mail.tamco.com.my"

then I add in mail.tamco.com.my into /etc/hosts. it give the server and ip result


2. echo test | sendmail -v alson.ng@tamco.com.my
alson.ng@tamco.com.my... tamco.com.my: Name server timeout
alson.ng@tamco.com.my... Transient parse error -- message queued for future delivery
alson.ng@tamco.com.my... queued


3. telnet 25

I am able to telnet
