not able to receive mail in hp-ux

[Gerard Powell]

I have configured sendmail on hp-ux. I am able to send mails but not receive. Can somebody help in this. Is there any entry that I have missed?

This is how I have configured it:

1. /etc/nsswitch.conf

hosts: files
aliases: files

2. /etc/resolv.conf

nameserver
domain

3. /etc/rc.config.d/mailservs

export SENDMAIL_SERVER=1
export SENDMAIL_SERVER_NAME=
export SENDMAIL_RECVONLY=0
export SENDMAIL_SENDONLY=0

4. /etc/mail/sendmail.cf

DS

5. stopped and started the sendmail service.

Not a very complete description.

"I am not able" is not a useful problem
description. What, exactly, did you do to
test it? What, exactly, happened when you
did that?

How, exactly?

As usual, showing actual commands with their
actual output can be more helpful than vague
descriptions and interpretations.

Can you hide any more potentially important

That's what's in /etc/mail/sendmail.cf, or
that's what you changed, or that's what you
added, or what?

1. Uname -a

HP-UX hptst B.11.00 U 9000/800 579706537 unlimited-user license


using elm I am able to send mails from gmp@hptst.cmcltd.com to say gmp@cmcltd.com.
but not able to send from gmp@cmcltd.com to gmp@hptst.cmcltd.com


the error I get
Host hptst.cmcltd.com not found.

The following recipients did not receive this message:



edited /etc/resolv.conf and put these entries

domain cmcltd.com
nameserver download.cmcltd.com


/etc/mail/sendmail.cf and put this entry

# "Smart" relay host (may be null)
DS172.16.11.11



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

Looks to me more like a name resolution
problem than a sendmail problem.

What's in /etc/hosts? Are you using DNS?

nslookup hptst.cmcltd.com

[Gerard Powell]

Dear Steven Schweda,

1. c:\>nslookup hptst.cmcltd.com

Server: download.cmcltd.com
Address: 172.16.2.2

Name: hptst.cmcltd.com
Address: 172.16.25.5

2. Yes. I am using DNS
/etc/hosts has the entries

#SMTP
172.16.11.1 cmcdak.cmcltd.com cmcdak
#DNS
172.16.2.2 cmcltd.com cmcltd
172.16.25.5 hptst.cmcltd.com hptst

[Steven Schweda]

> 1. c:\>nslookup hptst.cmcltd.com

Why does that look as if it were run on a
Windows system?

I'm now officially confused.

[Gerard Powell]

I connect remotely from a windows m/c on these systems, so I had given nslookup from windows system.

This output is from hptst system.
# nslookup hptst.cmcltd.com
Using /etc/hosts on: hptst

>but not able to send from gmp@cmcltd.com to gmp@hptst.cmcltd.com

You should be checking nslookup on the machine that is sending mail.

[Gerard Powell]

You are right not able to send from gmp@cmcltd.com to gmp@hptst.cmcltd.com

output from gmp@cmcltd.com m/c

$ nslookup hptst.cmcltd.com
Server: 172.16.2.2
Address: 172.16.2.2#53
