Sendmail problem.

[Gulam Mohiuddin]

We have four HP-UX servers with HP-UX 11 OS.
On two Servers if I issue the following command it works properly and I get E-mail message on my Outlook throgh our Exchange server.

$cat gulam.txt | sendmail gulam.mohiuddin@region.peel.on.ca

But on two other servers this commnad is not working. I have no idea what is the poeblem on those servers.

I need to figure out and resolve this problem so I can also send E-mails from them.

Please let me know what to check and what extra configuration is required.

Thanks.

Gulam.

Hi there,

Any error messages (also from /var/adm/syslog/mail.log )

[Gulam Mohiuddin]

Here is the mail.log file from the Server where this command is not working.

Thanks,

Gulam.

Have you set up the Smart Host on the servers not working? If not, make the entry in the /etc/mail/sendmail.cf file:

DSmyexchange.mydomain.com

Search through the sendmail.cf file looking for Smart. The DS will be there. Just make your additions and then stop/restart sendmail.

What is your output from 'mailq' ?

The output of $ps -ef|grep sendmail is as follows

sendmail: accepting connections on port 25

Here is the output of $sendmail -v ...

[/etc]$> sendmail -v gulam.mohiuddin@region.peel.on.ca

you can test the mail server to see if it delivers any mail for example do the following :-

telnet 25
Trying...
Connected to Escape character is '^]'.
(Microsoft Exchange Internet Mail Service ) ready
(Then type in :- )
HELO dev
250 OK
MAIL from:< your machine e.g. hpserver
250 OK - mail from
RCPT TO:250 OK - Recipient
DATA
354 Send data. End with CRLF.CRLF
test message
.
250 OK

If you don't get the mail then it is most likely a problem on the mail server. If the above does not work try it on the server that works that is what you should get .

Ah, you have not got you DNS configured properly. I am not sure, but I think the default sendmail.cf configuration needs DNS in order to function. DNS is not vital in order to get sendmail working - but it makes life *a lot* easyer.

Check your /etc/resolv.conf file.

If you are not using DNS cp nsswitch.conf from /usr/newconfig/etc/mail/nsswitch.conf to /etc/nsswitch.conf . Update the lines to read e.g hosts: files
services: files
networks: files
aliases: files
protocols: files

Update your /etc/mail/sendmail.cf (DS(MX netservername)) and DW too.
Inculde in /etc/mail/aliases (root :your email address)
stop and start sendmail
/sbin/init.d/sendmail stop/start

yes, your DNS is either not cofigured or configured incorrectly. In you /etc/nsswitch.conf file, look for the host line and make sure the arguments are..
hosts files dns nis

then make sure the hosts are in your /etc/hosts file..fully qualified too.

[Berlene Herren]

I agree with Chris, Allen and Kevin. Transient parse error is consistent with DNS problems.

Way to jump on this, guys!

[Gulam Mohiuddin]

Thanks everybody, this problem is over.

There was no /etc/nsswitch.conf file so when I created it, everything worked fine.

Thanks again.
