send error messages to my company email

[Karl_]

Hi,

Could anybody show me how to configure the HP-UX 11 sendmail to email me in my company email if there are errors in the HP server. We have a separate server for our email.

Your help is highly appreciated.

Thank you very much.

Karl

If you have an exchange server to use.

Add the following to the /etc/mail/sendmail.cf file

# "Smart" relay host
DSmsexchange (msexchange is your exchange server name)

Save the file.

The domain name should be included in the /etc/resolv.conf file

domain mydomain.com
nameserver 192.168.1.2
nameserver 192.168.1.3

Sendmail daemon will forward the mail to the exchange server.

Then restart the sendmail daemon
# /sbin/init.d/sendmail stop
# /sbin/init.d/sendmail start

Now, you can edit /etc/mail/aliases
# System Admistration aliases
root : youremail@domain.com

Re-initialize the alias database,
# sendmail -bi
Now all alert to root should be sent to your email box.

Hi twang,

We are using Lotus Notes Release 5.

Thanks again

[twang]

I have not used Notes, but with Exchange this is perfectly possible. After sendmail is setup and configured properly, if you are lucky you should be able to send a message to one of the addresses on Notes. It will need of the SMTP type. You can do a test to send the host file to a user on notes after performing the above steps:

# sendmail -v yourname@domain.com < /etc/hosts

Hi twang,

I trued testing it using

sendmail -v yourname@domain.com < /etc/hosts

It worked. Now I'll just wait for an error to confirm if it would really send an error message to my company email.

Is there a way to simulate an error so that I will confirm if it really sends a report to my company email?

Thank you very much for your help.

Karl.

Hi All,

Thanks for your reply. I have noticed an error in our mail.log:

=======================================================================================
May 20 04:16:55 oradev sendmail[17642]: EAB17642: to=root, delay=00:00:06, xdelay=00:00:00, mailer=relay, relay=celen.pasar.net.p
h.pasar.net.ph, stat=Host unknown (Name server: celen.pasar.net.ph.pasar.net.ph: host not found)
May 20 04:17:09 oradev sendmail[17642]: EAA17642: Saved message in /var/tmp/dead.letter
May 20 10:10:46 oradev sendmail[27199]: gethostbyaddr(192.168.42.237) failed: 1
=======================================================================================

As you may notice, the hostname has 2 domain name attached to it.. The hostname should only be celen.pasar.net.ph and not celen.pasar.net.ph.pasar.net.ph. Where do you think the problem came from?

Thanks again.

Hi,
To do a test to send the host file to root:

# mail root < /etc/hosts

Does it work?

regards tommy

[Karl_]

No, there was no mail received by root after the sendmail command. I checked it the dead.letter. The email was saved there. I have also checked the mail.log, it shows the same error as I have reported earlier.

[twang]

sendmail -v yourname@domain.com < /etc/hosts

As you mentioned it works before, does it work now?

[Joseph Loo]

hi,

may i know what is in /etc/resolv.conf, /etc/hosts and /etc/nsswitch.conf for your server?

if it is not convenient, u may like to extract to this post only the line where the affected dns, i.e. celen.pasar.net.ph.pasar.net.ph is found.

regards.

[twang]

Issue the following commands:
# nslookup celen.pasar.net.ph.pasar.net.ph
# nslookup celen.pasar.net.ph

[Karl_]

Hi twang,

Yes it works. Here is the output of the comand.

Hi twang,

Here are the result of the commands

# nslookup celen.pasar.net.ph.pasar.net.ph
Trying DNS
Trying NIS
looking up FILES
*** No address information is available for "celen.pasar.net.ph.pasar.net.ph"

# nslookup celen.pasar.net.ph

thanks again,

Hi Joseph

Im sorry i cant show you the ip address. I just replaced it with xxx.

/etc/resolv.conf,
domain pasar.net.ph
nameserver <192.xxx.xxx.xxx>

/etc/hosts
127.0.0.1 localhost loopback
192.xxx.xxx.xxx celen celen.pasar.net.ph

/etc/nsswitch.conf
We do not have nsswitch.conf file

[twang]

Can you look up the domain:

# nslookup yourdomain.com
or
# nslookup
>set type=mx
>yourdomain.com

[Karl_]

Hi twang

# nslookup pasar.net.ph
Name Server: ns.pasar.net.ph
Address: 192.xxx.xxx.xxx

Trying DNS
Trying NIS
looking up FILES
*** No address information is available for "pasar.net.ph"

# nslookup
Default Name Server: ns.pasar.net.ph
Address: 192.xxx.xxx.xxx

> set type=mx
> pasar.net.ph
Name Server: ns.pasar.net.ph
Address: 192.xxx.xxx.xxx

Trying DNS
pasar.net.ph preference = 10, mail exchanger = mail.pasar.net.ph
pasar.net.ph nameserver = ns.pasar.net.ph
mail.pasar.net.ph internet address = 192.xxx.xxx.xxx
ns.pasar.net.ph internet address = 192.xxx.xxx.xxx (different from the ip address above).

Karl

[Joseph Loo]

with no /etc/nsswitch.conf file, the server resolves any input from nslookup to DNS and then /etc/hosts, so that is okay.

now, let us look at your /etc/mail/sendmail.cf file.

search for Dj$w.Foo.COM, it should be either be commented or replace by (in your case),

Dj$w.pasar.net.ph

and for DS, it should be

DScelen.pasar.net.ph

now for /etc/mail/sendmail.cw file. do you have the following:

localhost
oradev
oradev.pasar
oradev.pasar.net
oradev.pasar.net.ph

regards.

[Karl_]

Hi Joseph,

I have already updated the sendmail.cf file. Below is the content of the sendmail.cw file
==============================
localhost
loopback
localhost
oradev
oradev.pasar
oradev.pasar.net
oradev.pasar.net.ph
===============================

Karl

[Joseph Loo]

could you just leave one localhost in /etc/mail/sendmail.cw file, i saw 2 lines.

afterwhich, do this to restart:

# /sbin/init.d/sendmail stop
# /sbin/init.d/sendmail start

regards.
