Re: Becoming Better

John Holder's blog post from 11 years ago about backups should cement for everyone that John fully understands what it is like to be a Zimbra customer (and that having good backups is not sufficient to claim you have a good disaster recovery plan...). It's still a fresh post: https://blog.zimbra.com...

Re: Can't install Zimbra 8.8.8 GA

8.8.8 is long past end of life.

Suggest you install 8.8.12.

Hope that helps,

Re: Web Admin and SMTP submission problems after server move+upgrade

Hey all, I did what seems to be a sloppy job migrating and upgrading Zimbra FOSS. I was running on Ubuntu 14.04LTS and rsynced it to a different Ubuntu 16.04LTS server, then "upgraded" from 8.8.8 to 8.8.8 using the Ubuntu 16 package. There were some errors but skipped checks on installati...

Re: Zimbra License file

our license is perpectual..we have no support from zimbra Are you have any idea about ?? Jordack’s post is totally correct. With a Perpetual License if you want to upgrade versions or get help from Zimbra you must also purchase a Support subscription. If you let Support lapse for a year or two and ...

Thank you


Nothing for you to do; the operating system manages swap usage, as well as allocations of RAM to buffers/cache etc.

Re: High consumption of memory in Zimbra + Centos 7

I’m not seeing anything there that gives me pause.

The two biggest consumers of RAM are MariaDB and the Java mailbox app. Neither “release” memory as users log off.

Make sure you have a swap file and some memory alerting configured and you should rest easy.

Re: High consumption of memory in Zimbra + Centos 7

I'm worried that I'll be neglected and that peak will reach the 24 GB installed and the server will collapse ... or will it run out of memory Always good to have a swap file for exactly that reason, but I think you’ll find the Zimbra installer sets things to use all the RAM you have, so a little sw...

Re: High consumption of memory in Zimbra + Centos 7

Java and MariaDB are allocated pools of memory based on how much RAM was present during the installation. Other components like Lucene will also use RAM irrespective of the number of users logged in. What you report seems neither unusual nor worrisome. Perhaps I missed something; why are you concern...

Re: How Disable Antivirus and only use spamassassin?

The reason I like to keep Zimbra's AS/AV in place even when you have inbound and outbound AS/AV protection (from IronPort, Mimecast, Barracuda or similar) is that Zimbra routes email for any domain it hosts entirely internally. So, if one mailbox starts emailing malware to every other mailbox on the...

If you cleaned it but didn't patch it, you will just get reinfected.
