====== How can i disable Postgrey? ======
By default postgrey is enabled in the ispCP postfix configuration.
If you don´t want to use postgrey you can disable it this way:

Open your **/etc/postfix/main.cf** and comment the following line
<code>
check_policy_service inet:127.0.0.1:60000,
</code>
like this
<code>
#check_policy_service inet:127.0.0.1:60000,
</code>
Do not forget to restart postfix after this change.
<cli>
# /etc/init.d/postfix restart
</cli>
Then you can stop postgrey.
<cli>
# /etc/init.d/postgrey stop
</cli>
You should also remove it from the startup scripts.
