we have been testing a multi server setup with one gateway/ldap host and two mailbox servers. All are running under OS X (and Zimbra Network Edition 5.0.19).
As we are not sure about sticking with OS X, we set up a third mailbox server under Scientific Linux (an RHEL clone). The server works and seems to be successfully integrated into our existing setup. However, there are two problems:
- In the Administration Console, on the Server Status page, only our two OS X mailbox servers are listed. The RHEL mailbox server is missing. It shows up on other pages (Domains, Servers, Server stats) of the Administration Console, but not on the Server Status page. This is a minor problem, of course.
- Moving mailboxes between OS X and RHEL is not working correctly. It seems, as if only the Inbox is being moved. Everything else (Email Folders, Tasks, Calendars, Documents, and even custom Tags) is missing. This happens in both directions. When moving the mailbox back to the originating server, everything is available again. All data is available again, even if one has purged the old mailbox on the originating server. So it looks, as if no data is lost when moving, it just seems inaccessible on the new server.
I did not find anything suspicious in the logs, the mailbox-move is logged from start to finish without any errors or warnings.
Should it - in theory - be possible to mix mailbox servers with different OSes or are there any definite reasons, why this can not work? Has any one tried that before?
Are there any suggestions, where I could start debugging this?
