sendmail setting in HP UX 11.23

[Peter Yu]

Hi Guru,
I have two servers: host1 and host2, both are HP UX 11.23, I am trying to setup the sendmail, from my point, two servers sendmail configuration are identical, but the result are different. For below test, I can receive the email sent from host1 to my hotmail, but the one sent from host2 remains in the queue, cannot connect to my relay sever. file /etc/rc.config.d/mailservs, /etc/mail/sendmial.cf, /etc/mail/aliases, /etc/mail/sendmail.cw are contain same setting.
root@host1:/etc/mail$ /usr/sbin/sendmail -v abc@hotmail.com
test mail from host1.

Looking at the mail transcripts, it seems like your host2 can not identify itself Look at the IP addresses introduced. host1 seems to advertise (tell) it IP address to the mail relay server whereas host2 advertise the 127.0.0.1 whih is the local host. Are you sure you can connect any other server from host2 ? Make sure on host2 you have valid /etc/rc.config.d/netconf and /etc/hosts files.

Shalom Peter,

Probably the sendmail.cf configuration is not consistent.

Also note that host2 is accepting the mail for local delivery to the local sendmail daemon, which is running.

If sendmail is not running on host1 that could be the problem.

Standard configuration for the corporate environment is to relay mail via a local smtp relay server.

DSrelayserverhostname

or
DS
[192.168.0.10]

Where 192.168.0.10 is the local relay server.

The second approach, in sendmail.cf avoids mail delivery problems if DNS is down.

Mel,
Thans for your reply, I checked the netconf and hosts file, it is OK. I can ping mail relay server from both host1 and host2.

Steven,
file sendmail.cf is identical, both has DSsmtp.test.com

and I can ping smtp.test.com form both server.

What confuse me is same setting, one connect to relay server, one connect to local daemon...

Best regards,
Peter

It remains same issue, anybody can help, thanks.

From server2 (not working server)

telnet 192.168.0.10 25

what do you get in response ? Is it timing out or are you getting something like

EHLO server2 .... etc..

[Peter Yu]

Mel,
from host1 and host2 do telnet 192.168.0.10 25, both will timeout.
But if I telnet smtp.test.com 25,both get in. I can they run HELO, MAIL FROM, ...


Best regards,

Issue fixed...
the issue comes from submit.cf file, host1 don't have this file, but host2 has. But unfortunat the value in host2 has wrong value for smtp realy. so change it to correct value works.

Best regards,
Peter
