is your sendmail act as relay server or forwarding?

check in /etc/resolv.conf file.

Have you looked at those files in mailq?
vi /var/spool/mqueue/?fKAA02045

Re: Sendmail Issue

Omprakash_2 — Tue, 03 Feb 2009 04:52:01 GMT

Hi,

The mqueue directory is empty. I have removed all the files before.

Dear All,

Its displaying the below mentioned. Then i tried to send mail but no response.

# newaliases
/etc/mail/aliases: 8 aliases, longest 15 bytes, 109 bytes total

Hello,

OK, you fixed one problem.

Now the next.

a) Test if local mail deliver works.

# mailx -s test root

If the mail gets delivered to root,
than local delivery is fine.

b) Judging by the document you sent,
remote email delivery doe snot work.

Two options:

1. Your server must be configured to reach
internet freely (that is quite suicidal
and insecure),

or

2. Your sendmail setup must be configured
to use Smart Host (look for DS line
in /etc/mail/sendmail.cf).

Most probably that line currently loosk like:

DS

.. And what is should look like is:

DSsmtprelay

whene smtprelay is a hostname for the
machine that acts as email gateway in
your company.

Hi,

>Where I should the local inbox in server???

(should what?)

There are no inboxes with sendmail. There is /var/mail/ for each user. There is /var/spool/mqueue/ for outgoing mail.

Hi,

I have checked the local inbox, mails is there. But my problem is mail is not going outside in the same domain. Can you pls suggest me for the same

>But my problem is mail is not going outside in the same domain.

Have you done what VK2COT said?
Have you checked /var/adm/syslog/mail.log?

Re: Sendmail Issue

Omprakash_2 — Tue, 03 Feb 2009 09:34:05 GMT

Yes, i have checked

Re: Sendmail Issue

VK2COT — Tue, 03 Feb 2009 09:45:45 GMT

Hello Omprakash,

I had to smile at your last response.

Dennis asked you: Have you checked /var/adm/syslog/mail.log?

You responded: Yes, i have checked.

This short answer reminds me of a funny scene
in one of Pink Panther films where
the Inspector Cluso (sp?) asked a Swiss
person if he knew the current time. The guy
responded "Yes" and walked away :)

What Dennis meant by his question was:

What does the log file say?

Most probably, the message is deferred because the server cannot contact remote
mail server or it cannot resolve domain name
for the recipient.

Hence, as we said before, you need to
set up sendmail with Smarthost support.

Cheers,

VK2COT

Smarthost support.

Can you provide me how to make this smarthost support setup. Hey I am new to HP UX servers, so required a huge support to solve a small issue.

Re: Sendmail Issue

VK2COT — Tue, 03 Feb 2009 10:30:17 GMT

Hello,

Sendmail setup is not specific to HP-UX.
It is common to many Unices and Linux.

Simplest method. Let's assume your smarthost
is hostname myhost.mydom.dom, or just
myhost, or its IP address is
192.168.5.20.

Edit /etc/mail/sendmail.cf and
look for line "DS" (CAPITALS ARE IMPORTANT!).

Replace:

DS

with

DSmyhost.mydom.dom

or

DSmyhost

or

DS192.168.5.20

Then, restart sendmail:

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

Note that myhost or myhost.mydom.dom MUST
be resolvable on your HP-UX server.
Hint: check /etc/nsswitch.conf
and probably /etc/resolv.conf (unless
you, for some reason use LDAP or NIS/NIS+).

If you have multiple smarthosts in your company, you can even do this:

DShostA:hostB:hostC

Or even

DS[hostA]:[hostB]:[hostC]

The entries with square brackets
mean "do not use DNS to resolve hostnames"...

Cheers,

VK2COT

Hi,

As you said i have added the DS entries in sendmail.cf file, Still my problem is not resoloved.

I have compared the same file in another HP UX server, but i dont find any entery in DS.

One thing i like to share with you is, now i am getting msg like "you have a mail".

Have you read this mail? It may be a bounce message?
