since we updated from Snow Leopard to Lion, we've a serious Problem with Zimbra and Apple Mail.
Apple Mail doesn't recognize any folder of our Zimbra Accounts, it _ONLY_ displays the inbox.
We conntect our Apple Mail clients with IMAP to Zimbra.
I've tested the Apple Mail Client, with some of my other Email Accounts (yahoo, gmail, qmail) and there everything is working.
I hope you can help me.
