Hi Zhang,

I have to install a new email server. I will choose Nginx as webserver with LDAP backend. The question is:

When you are at the optional components screen, I will not choose Awstat to be installed. Does it cause Policy-d (Cluebringer) is not installed too? What is the consequence of that configuration?

Thank you so much,
