[rhn-users] sendmail problem, can't send to external email account

[winai.p at cpf.co.th]

Dear all,

Please help me,

I have problem about sendmail. I can't send to external email account when 
i used command following

[oracle] $cat logbackup.log | /usr/sbin/sendmail -v winai.p at cpf.co.th

result is : WARNING: local host name (dbora-swt01) is not qualified; fix 
$j in config file
         winai.p at cpf.co.th... Deferred: Name server: cpmail01: host name 
lookup failure

I'm using cpmail01 as smtp server. 
I'm already add "cpmail01" to my hosts file and i don't set DNS server

I can ping cpmail01 and I can sendmail to this account by telnet with port 
25 to cpmail01 .

I don't sure to config sendmail.mc.

Thanks in advance.

Winai.
