Sendmail issue - missing logs, can't receive mails

Hi,

I'm having some problems with sendmail in Linux. The thing is when I type the following command to send an e-mail:

sendmail bartoszk@companydomain.pl< test.txt

it looks like it executed but I don't receive the mail. The file test.txt looks like that:

To: serwis@ubuntu-server.linux.companydomain.pl
Subject: Tests
From: serwis@linux.companydomain.pl

TestTestTestTestTest

Logs show something like that:

$.1.119], dsn=4.1.8, stat=Deferred: 450 4.1.8 <root@ubuntu-server.linux.companydomain.pl>: Sender address rejected: Domain not found</root@ubuntu-server.linux.companydomain.pl>

In the /etc/hosts there are following lines:

127.0.0.1  localhost  localhost.linux.companydomain.pl
127.0.1.1  rtnagios  rtnagios.companydomain.pl
127.0.1.1  ubuntu-server  ubuntu-server.linux.companydomain.pl
192.168.1.119  linux  linux.companydomain.pl
127.0.0.1  companydomain companydomain.pl

# The following lines are desirable for IPv6 capable hosts
#::1  ip6-localhost ip6-loopback
#fe00::0 ip6-localnet
#ff00::0 ip6-mcastprefix
#ff02::1 ip6-allnodes
#ff02::2 ip6-allrouters

The sendmail.mc file is:

Sending mails via

sendmail -fserwis@linux.companydomain.pl bartoszk@companydomain.pl < test.txt

doesn't work either.

linux.companydomain.pl digged:

root@ubuntu-server:/home/companydomain# dig linux.companydomain.pl

The command:

grep -iw from /var/log/mail*

output:

wklej.to/Bbe0T (it's a link because the log file is far too long to paste it here)

What's interesting is the fact that there are no logs from 20th November. The question is: why? There should also be logs from 19th November, since I started struggling with sendmail on Wednesday. But there are not, which is strange. System date/time is set correctly, so the problem isn't there.

Another command:

ps -aux|egrep '(sendmail|syslog)'

gave that output:

How can I fix it?
