The Postfix configuration files are located in /etc/postfix. Edit /etc/postfix/main.cf and add check_policy_service inet:127.0.0.1:60000 to the smtpd_recipient_restrictions. It should look something like this :
smtpd_recipient_restrictions = permit_sasl_authenticated,
I don't see that this is configurable using ISPconfig ...
This can not be configurable in ISPConfig for clients and resellers because greylisting is activated once for the whole server (see your config snipped above) and can not be configured on a reseller / client basis because there is nothing to be configured. The greylisting daemon does not know what a client or reseller is, so we can not enable / disable greylisting on a reseller or client basis.
