Re: Mail server sending spam from zimbra@mydomain.com

I did clean and I did patch.
I just wondered if this 100% cpu would be related to this particular issue.
In any case, I killed it and restarted Zimbra yesterday. Everything seems normal so far.

Thank you for your help.

Re: Mail server sending spam from zimbra@mydomain.com

It's already been mentioned that you may have a compromised (i.e. hacked) server, read the thread that's been posted in the link earlier to confirm if it has or not. Yes. I already clean it following this link . My question now is about the cpuset thing. ps aux | grep cpuset: zimbra 9277 100 0.0 13...

Re: Mail server sending spam from zimbra@mydomain.com

Okay, I updated to 8.7.11_GA_3800.NETWORKING.

One question: I'm seeing a process that just says "[cpuset]" and it's consuming 100% of one of my cores. It's running for 71 min+ and I just restarted zimbra in order to update. Could this be related?

Re: How to properly backup Zimbra?

Here's a little script I use. Nothing fancy but gets the job done. Modify for your environment and test before using. In the event of disaster, just restore /opt/zimbra and copy data.mdb back to /opt/zimbra/data/ldap/mdb/db and set permissions. #!/bin/bash #Rsync Zimbra while still online...reduces...

How to properly backup Zimbra?

Currently I'm copying via rdiff-backup the Zimbra directory (/opt/zimbra) to another server. But is this a good way to back it up? I'm thinking on using Bacula instead, but I'm not sure.
