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.

Re: CVE-2019-9670 being actively exploited

Folks, Can anyone who has been hacked say definitively that, after patching and performing eradication, that they have suffered no further exploits? And if so, could you post your specific eradication steps please? I've read through the post history several times now; lots of great info here but fin...

Re: Thoughts regarding X-Originating-IP headers

I think it could be good to reduce the RCVD_IN_PBL yes.

Interesting old discussion on this here:

Re: Thoughts regarding X-Originating-IP headers

Years ago I would turn off X-Originating-IP, but now I keep it turned on because It is necessary for the IP blocking capability of DoSFilter, which I find very useful. The false positives in my experience are all from ZCO users on dynamic and other IP addresses that SpamAssassin wants to block/score...
