Linux distro: SuSE 8.0
Sendmail: version 8.12.2

I've been unsuccessful connecting to sendmail on any interface other than
127.0.0.1 If I try to send a mail to the sendmail process running on this
host with sendmail(for testing purposes) with the following command:

/usr/sbin/sendmail -Cclient.cf -v -d user1
(this is an exercise in a book I've beem following: "sendmail" by
Costales/Allman)

user1... Connecting to host1.domain via hub...
makeconnection (host1.domain.net. [192.168.1.2].25 (2))
makeconnection:fd=6
Connect failed (Connection refused by host1.domain.)
openmailer: makeconnection => stat=75, errno=111

However it works just fine if I send a mail this way:

/usr/sbin/sendmail -v -d user1

user1... Connecting to localhost.domain. via relay...
makeconnection (localhost.domain). [127.0.0.1].25 (2))
makeconnection: fd=6
smtpinit ....

Furthermore, if I try to telnet:

$> telnet 192.168.1.2 25
Trying 192.168.1.2...
telnet: connect to address 192.168.1.2: Connection refused

But

$> telnet 127.0.0.1 25
Trying 127.0.0.1...
Connected to 127.0.0.1..
220 host1.domain ESMTP Sendmail 8.12.3/8.12.3/SuSE Linux 0.6; ...

Works

Also netstat -a gives :

tcp 0 0 localhost:smtp *:* LISTEN

as the only entry for smtp

I tried everything I could imagine to get sendmail to listen to interface
other than 127.0.0.1
In sendmail.cf I changed daemon port options to:

O DaemonPortOptions=Name=MTA,Addr=192.168.1.2

This has no effect! I even tried to change the port just to see if it would
change anything:

O DaemonPortOptions=Name=MTA,Port=26

The port didn't change at all!
(I did restart the server)

Furthermore I'm not running any firewalls and ifconfig confirms eth1
interface up configured with ip 192.168.1.2

Now I am quite confused. Am I missing something here?

I have googled extensively, read over the faq, and gone over the operating
maunal. Nothing seems to address my particular problem.

Thanks,
Happy New Year,

George
