Tips & Tricks : Zimbra Collaboration 8.8.6 è disponibile

Zimbra Collaboration 8.8.6 è uscita! Questa versione ha introdotto miglioramenti per i moduli NG e per gli nginx zimbraVirtualHostname.


A dicembre Zimbra ha lanciato Zimbra Collaboration 8.8, introducendo i moduli NG, una nuova serie di funzionalità all’avanguardia per backup e ripristino in tempo reale, la possibilità di spostare i blob utilizzati meno frequentemente in Amazon S3, un modulo per amministratori delegati più semplice, ma più potente e la tanto attesa capacità di sincronizzare le risorse condivise con tutti i tuoi dispositivi .

Nella release 8.8.6 sono state effettuate 30 correzioni per i moduli NG, correzioni importanti per EWS e per chi utilizza IMAP. Dopo i feedback ricevuti sia dai clienti sia dalla community sulla gestione della sicurezza nginx della versione 8.8.5, Zimbra ha introdotto un nuovo attrobuto ldap per coloro che desiderano perfezionare ulteriormente questa funzionalità:


Name zimbraReverseProxyStrictServerNameEnabled
Description Configure the default server block in ‘nginx.conf.web.https?.default.template’ to return a default HTTP response for all unconfigured host names. See also related attributes ‘zimbraVirtualHostname’ and ‘zimbraVirtualIPAddress’.
Type boolean
Optional in globalConfig,server
Requires restart nginxproxy
