Hi All,

Nice to be a part of a good mail server. I have successfully moved from exchange 2003 to iredmail and i have only one hurdle in completing this.  I want to share public folders that should reside in my server and i want to control the access of the users in a centralized location. Kindly guide me through this! thank you.
