Installing Blackberry Enterprise Server (ZCB/BES) in a Zimbra Proxy Environment
Currently the Zimbra Proxy server does not proxies requests on Port 7071. The Zimbra Proxy documentations suggests to turn off HTTP SSL on the mailbox servers and offloads it to the Zimbra Proxies, but the proxy servers do not handle 7071 like the mailbox servers do.
ZCB/BES needs Ports 443/8443 and 7071 to work. Until Bug 31053 is resolved to proxy port 7071 you will need to apply the below steps for ZCB/BES to function properly.
When creating both BlackberryServer and BlackberryManager profiles, you need to point these to one of the Zimbra Mailstores.
All Zimbra mailstores need to be have HTTPS enabled. To enable https please follow below wiki. We recommend setting the mailstore to use 'BOTH' for mail mode.
The BES server must be able to access *all mailstores* directly on ports 7071 and 443/8443. This is because ZCB uses the Zimbra "waitset()" command, and must be able to directly connect to the mailstore on which each user resides. After retrieving the user location on port 7071, BES/ZCB will connect to port 443 or 8443 on the proper mailstore for each user it syncs.
