[CentOS] Sendmail problem - baffled

Some more info. Below is a more complete telnet session from backup mail 
server (mx2.greenspot.fi) to primary mail server (mail.greenspot.fi).

It only proves that sending mail works fine from command-line. But my 
sendmail setup cannot do the same.

I wrote that MAILER-DAEMON can get mail through. I am not actually sure 
about that. (One warning message did come through, but maybe it was 
because something I changed in the config - not sure anymore.)

Here's the successful telnet session:

[root at mx2 ~]# telnet mail.greenspot.fi 25
Connected to mail.greenspot.fi (
Escape character is '^]'.
220 mail.greenspot.fi ESMTP Sendmail; Tue, 15 May 2012 23:17:59 +0300
