dijichi2 I certainly respect your efforts for the zimbra community with Solaris etc, however I think you are way off base with your RHEL argument.
RH do not develope their product entirely, in reality they do not have the staff numbers to actually develop all the packages which they package for release. (Yes I know that employ a lot of people that develop and put back into the community, however RHEL is still a derived work from the community efforts and of other vendors)
RH's business model is to offer customers paid subscriptions to support, training and professional services for a product thats beens fine tuned but is still based on community development.
No one has the right to call CentOS users Pirates, after all if you get to the nitty gritty RH are profitting off alot of peoples work without paying them.
Anyone that thinks that way has obviously doesn't understand the idea of communtiy development and open source.
Back on topic, it is obvious that we have the interest of the CentOS team in this thread and Zimbra would be well advised to release the information about this so called CentOS bug thats not in RHEL to them so it can be either fixed or have CentOS name cleared of all charges :-)
