Hi, I have installed IMAP 4.7 on a Debian Potato kernel 2.2.17 Linux server and Netscape 4.76-1 on a Debian Potato kernel 2.4.1 Linux workstation. How can I configured the IMAP SERVER so that the following can be enabled: Support for folder which contains both messages and sub-folders, i.e. folder --> Messages --> Sub-Folder --> Messages --> Sub-Sub-Folder --> Messages --> Sub-Sub-Sub-Folder, and so on..... Many thanks for your help. Wilson
