How to install DNScache after general installation?

Re: Zimbra Collaboration 8.7.x and Ubuntu OS update corrupts/removes Zimbra installation

I have a side question. We have a few Ubuntu 14.04.5 LTS servers with Zimbra 8.6 (Release 8.6.0.GA.1153.UBUNTU14.64 UBUNTU14_64 FOSS edition, Patch 8.6.0_P6.) I'm wondering if it is recommended to upgrade Ubuntu first and then Zimbra to 8.7, or if it is recommended to upgrade zimbra to 8.7 and stay ...

Re: error in network service after one wrong login

I am also getting this for users that are on our internal network while using Zimbra through the web GUI. It's only occasionally and for random users. Here is the error: external LDAP auth failed, LDAP error: - unable to ldap authenticate: 80090308: LdapErr: DSID-0C0903A8, comment: AcceptSecurityCon...

Re: No ACL tab in Distribution Lists

Any idea why my ACL tab is not showing up in the distribution lists pages in the web admin GUI? I see here in this WIKI link that the "ACL" tab is there, but I don't have it on my installation. https://wiki.zimbra.com/wiki/Ajcody-How-To-Setup-sendAsDistList-Right-And-Persona-For-A-Distribu...

How to copy a class of service to the default COS

Hi, A few weeks ago, we upgraded from Zimbra 7.x to 8.6.0. We used the zextras export and import method to export all data and then import it to a completely new server. One of the issues that we have is that all of our settings are now in a COS called "default_restored_zimbra.<ourdomain.com>&q...

Re: Q: Configuration Change - "Client host rejected: cannot find your hostname"

There are many poorly configured mail servers and clients, you may want to consider whether it's worth using the protocol and DNS checks (I don't bother using them).
