Editing Zimbra Archive Server (section)

==Script== 
The following script to add users automatically on the archive server, and also to the 'archivelist' file. Run this on the main server, and all users will be automatically added. You can place it in the crontab for every half an hour, so that when a new user is created on the main server, he/she will be automatically added to the archive server. SSH using keys (password-less ssh) between the main and archive server is necessary for the script to function. 

 #!/bin/bash
 # ENSURE ALL THE SERVERS HAVE PASSWORDLESS SSH AUTHENTICATON (Login using keys),
 # OR THE SCRIPT WILL FAIL

 #
 #  This script will add users that are present on the main Zimbra server, but not
 #  on the archival server. It will also make the appropriate changes in postfix.
