Your ssh isn't exiting because a child process, in this case zimbra, remains. As some others have suggested, this is due to ssh waiting on both stdin and stdout of the child process to close.
For example, if you do the following, you'll experience a hang: pc1$ ssh pc2 pc2$ xterm & pc2$ logout ...hang without exit.. until you close the xterm. Something like the following should behave more like you expect: pc1$ ssh pc2 pc2$ xterm < /dev/null >& /dev/null & pc2$ logout ...ssh session terminates pc1$ Hope this helps.
