tlug: sendmail.cf

[Yong-Ming Hua <yhua@example.com>]

Hello,
     I am setting up sendmail right now. I can make sendmail.cf but when
I try
sendmai doing such as
sendmail -bt -d0 < /dev/null
I get this message,

short domain name....
.
.
.
.
============================
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter <ruleset> <address>

and then i try
# sendmail -v user(in our host) < /dev/null
user ... connecting to pmlocal ...
user ....Sent

of course it should be sent cause I use procmail IN the host.

but! whenever I try to do
#sendmail -v user@example.com machine from any OUTSIDE machine,
connection is not to be made. No connection.

network is working with LAN.
telnet, ftp all those work.
I run sendmail -bd but it gets killed right away.
Is writing sendmail.cf that complicated? Where am I wrong?
I am using CF-3.7Wp12 on turbolinux.
any ?

Yong-Ming
