nagios 3.0.5 email notifications fail

[alex alex]

Hi all,
I have nagios 3.0.5 installed and it seems that it is working ok but no
notifications are sent. Instead, in /home/nagios/dead.letter the messages
keep arriving. The problem seems to be due to mail headers :

"From nagios Fri Jan  9 09:38:31 2009
Return-Path: <nagios>
Received: (from nagios at localhost)
        by localhost.localdomain (8.14.1/8.14.1/Submit) id n097cVWc011912
        for $; Fri, 9 Jan 2009 09:38:31 +0200
Date: Fri, 9 Jan 2009 09:38:31 +0200
From: nagios
Message-Id: <200901090738.n097cVWc011912 at localhost.localdomain>
To: $
Subject: **  Service Alert: ITM_M._Ciuc/is_alive is OK **"

Somehow it seems that no user address is found (or the address $ is used ).
Also, the mail log says the same thing:

Jan  9 12:33:14 localhost sendmail[11185]: n09AXEi5011185: from=nagios,
size=276, class=0, nrcpts=1,

relay=nagios at localhost
Jan  9 12:33:14 localhost sendmail[11186]: n09AXE29011186:

pri=30276, relay=[127.0.0.1] [127.0.0.1], dsn=5.1.1, stat=User unknown
Jan  9 12:33:14 localhost sendmail[11186]: n09AXE29011186:
from=<nagios at localhost.localdomain>, size=276, class=0, nrcpts=0,
proto=ESMTP, daemon=Daemon0, relay=localhost.localdomain [127.0.0.1]

Do you encounter such behaviour?

Some relevant config files are as below:


define host {
        host_name                       host1
        alias                           host1
        address                         172.30.129.67
        use                             generic_business_hour
}

        members                         nagios,user
}


define contact {
