I have an open support ticket for 7 days now for a simple issue with my cbpolicyd config.
I have been using Zimbra for years, and this is the worst support I have ever had, so in desperation I am turning to the forums.

What I want.
Proper greylisting.
Either proper config for cdpolicyd or a way to get postgrey working with Release 8.0.5.GA.5839.UBUNTU10.64 UBUNTU10_64 NETWORK edition

What I have.
A vast amount of spam messages, users bitching and complaining about the increase in spam after the upgrade.
Three replies from Zimbra support in seven days asking for logs, completely disregarding my original request and generally pissing me off.
No time to mess around with a mail server that should be working like it did before the upgrade.
