Every now and then my zimbra server crashes and it is just an absolute mess to try and get it running again (usually coz the server crashed and results in a corrupted file system).

So I restore it from a nightly backup, but local clients running IMAP lose any locally synchronised emails. Clients are using thunderbird and iPhone.

I was just wondering if anyone knows of a way around it? (without changing to pop3). It would be great if the local email could sync back onto the server rather than just vanishing off the client without a trace. Or is this just by design when using IMAP?.

Perhaps I need to disconnect the account on the client and register a new account, then copy any missing emails into the new one? That doesn't sound fun :/

What have other people done when restoring from a backup?

Thanks! Ryan
