Hello,

I'm getting the following error (Server configuration problem) in /var/log/mail.log and the mailserver stopped working. I have restarted the entire server and the problem was solved for a while, but it started coming again.

I tried the following but no use:

 $ apt-get install python-setuptools
 $ easy_install DBUtils
 $ python -c "import DBUtils; print DBUtils.__version__"

Could you please suggest a solution ?
Thanks.

Port 10031 is Policyd or Cluebringer service, and it's NOT running, please try to start it.
Or, temporarily disable Policyd/Cluebringer integration in Postfix config file /etc/postfix/main.cf, by removing "check_policy_service inet:127.0.0.1:10031", then try to make Policyd/Cluebringer working, and re-enable the integration in main.cf.

Port 10031 is cluebringer.
I have restarted the cluebringer: # /etc/init.d/postfix-cluebringer restart

I didn't find anything called policyd. But I have found a package named policyd-weight and it was not installed. So I installed that. Is it fine ?

Re: Server configuration problem

policyd-weight is not policyd, they're different softwares.

On your server, it's postfix-cluebringer service. Please make sure it's running.

Re: Server configuration problem

If cluebringer is running, Postfix should be fine. Any new error in Postfix log file? What's the issue now?

There are no errors in /var/log/mail.log right now. But the error "Server configuration problem", which I have reported in my first message came when cluebringer was working fine. I think that will start coming when there are too many connections.

Re: Server configuration problem

Any error in Cluebringer log file? /var/log/cbpolicyd.log.

If no related log, please turn on debug mode in Cluebringer, and extract related log if it happened again.
