[RCU] Zimbra server and roundcube INBOX messages list problems

Hi,

I have a problem with my zimbra server 7.2.3 with which, however, use rouncube as imap client , when a new message arrives, the number of unread messages in INBOX on the left box is updated while the list of messages to the center box (subject, date, sender, etc.. ) it does not appear, appears only changing folder.

I've tried various settings on zimbra, I also tried to enable and / or disable the proxy imap but it does not work.

I also tried various settings in IMAP section in CR especially with imap_force_caps but does not work.

Any ideas ?

Thank you Marco
