There seem to be some differences in the installation and configuration procedure as described in the Wiki at Improving Anti-spam system - Zimbra :: Wiki, the postfix-policyd wiki, Postfix Policyd - Zimbra :: Wiki, and the INSTALL instructions that came with the policyd v2 tarball.

v2 looks like it is now called "cluebringer" (cbpolicyd).

I just want to be sure that I install the software properly, create the database, and configure it without disrupting the existing Zimbra implementation.

This looks like it might also complicate future upgrades.

Has anyone done this and can assist me?
