Get variable limit exceeded

[pineapple]

Hello

I am having a few problems after building a new server following the ISPConfig3 tutorial with Debian Squeeze, Bind and Dovecot.

The Bind service is not running and when I restart it I get

/etc/init.d/bind9 restart
Stopping domain name service...: bind9rndc: connect failed: 127.0.0.1#953: connection refused

Checking the syslog I see nothing about Bind but find some worrying errors about ISPConfig:

Oct 10 08:01:35 sydney suhosin[7410]: ALERT - configured GET variable limit exceeded - dropped variable 'refresh' (attacker 'My 'IP Address', file '/usr/local/ispconfig/interface/web/monitor/show_sys_state.php')

Lastly, and possible unrelated, if I restart the server, Postfix reports that Port 25 is already in use and gives the warning:

warning: Mail system is down -- accessing queue directly

I discovered that sendmail was operating and by stopping sendmail I was able to start Postfix. But when I try to remove sendmail the system reports that it is not installed.

Any advice on any of these goings on would be much appreciated.

Thanks.
