It didn't say anything. There was no record of any failure.

One issue was a domain. I am not sure why it has worked before and one
day it stopped, but to continue on; i still have a problem.

http://mail.python.org/pipermail/mailman-users/2005-May/044742.html
I did following test which showed me that when i use my
SMTPHOST='example.com' i would not connect, which explains the time
out.

I have added my webpage address to /etc/hosts (example.com was not there before)

fixed hosts file looks like:
mycomputer:/home/lucas# cat /etc/hosts
127.0.0.1 localhost example.com mycomputer

I have tested it by(would be nice to have this test included with
mailman as testmailman.py or something like that):
>su list
>python
>>> import smtplib
>>> SMTPHOST = 'localhost'
>>> SMTPPORT = 0
>>> x = smtplib.SMTP()
>>> x.connect(SMTPHOST, SMTPPORT)
(220, 'mycomp.example.com ESMTP Postfix (Debian/GNU)')
>>> x.close
<bound method SMTP.close of <smtplib.SMTP instance at 0x4021a5ec>>
>>> x.close()
>>> SMTPHOST = 'example.com'
>>> x.connect(SMTPHOST, SMTPPORT)
(220, 'mycomp.example.com ESMTP Postfix (Debian/GNU)')
>>> x.close()
>>> SMTPHOST = 'mycomp'
>>> x.connect(SMTPHOST, SMTPPORT)
(220, 'mycomp.example.com ESMTP Postfix (Debian/GNU)')
>>> x.close()

now it seemd to work for a second, it sent few mails but now:
 cat /var/log/mail.log
 says:

I changed the Mailman/Handlers/SMTPDirect.py as follows.
    def __connect(self):
        self.__conn = smtplib.SMTP()
        self.__conn.connect(mm_cfg.SMTPHOST, mm_cfg.SMTPPORT)
        self.__numsessions = mm_cfg.SMTP_MAX_SESSIONS_PER_CONNECTION
and add a line so it becomes
    def __connect(self):
        self.__conn = smtplib.SMTP()
        self.__conn.set_debuglevel(1)
        self.__conn.connect(mm_cfg.SMTPHOST, mm_cfg.SMTPPORT)
        self.__numsessions = mm_cfg.SMTP_MAX_SESSIONS_PER_CONNECTION

cat /var/log/mailman/smtp-fail says:

What could be causing the problem?

is file permission like this normal?
/var/lib/mailman/bin
py files are in group list
but pyo or pyc are in group root
