[Dipl.-Ing. Edith Kemeny]

Dear All

I use mailman 2.0.7 (and RedHat Linux 6.2)
I can create a list and user can also subscribe to the list via web

The problem is:  THE MAILS; WHICH I SEND TO THE LIST, WILL NOT BE POSTED

/home/mailman/logs
"error" - is emty
"smtp" and "grunner" - not exist, it it wrong with something?
"post" and "subscribe" - seem to be all rigth:

Is there some other file to find the problem?
Why does not exist the file grunner in /home/mailman/logs?

Thank you for help
