I would like to allow only localhost, but I don’t know if I should remove all these mta information.

It's quite possible you don't have a problem. My apologies for that info I posted about postfix, I can't really understand where I got it - it must be my advancing years and your output is what the command should show. Can you explain in a bit more detail what the my networks entry is showing, are ...

Ops, so I think I have a huge problem: root@mecmail:/var/log# ps aux | grep postfix postfix 9115 0.0 0.0 142636 8432 ?

Have you had a look in the Zimbra log to see if any of these addresses appear there? Is it possible you have any compromised accounts? Does your ZimbraMtaMyNetworks contain the correct settings for your installation and nothing extraneous in there? Hello, In my zimbra.log I don't have anything abou...

Let's go back a step, you should always give the version of ZCS that's in use by posting the full output of the following command: zmcontrol -v Ok, my version is: Release 8.8.12.GA.3794.UBUNTU14.64 UBUNTU14_64 FOSS edition, Patch 8.8.12_P1 proxy. I had that problem with the exploit´s one or two mon...

I don't really understand what you're describing, it sounds like you're allowing another server to relay through your server - is that correct? If it is then it sounds like you have an open relay, you can check that via one of the (many) sites on the internet that provide this service - I'd suggest...

Hello, First of all, thanks for the help. Currently, I installed a relay system to get better management from my sent emails. One thing I notice is that my zimbra is sending from hosts that are not registered, is there any solution to avoid it? For example, Host test.com is sending email but is not ...

I was facing the exact same problem, solved with it: https://sebastian.marsching.com/blog/archives/124-OpenDKIM-bug-in-Zimbra-Collaboration-Server.html Recently I stumbled across a bug in the OpenDKIM configuration of the Zimbra Collaboration Server. In ZCS 8.0.3 (Community Edition, but I guess the ...

My currently situation is that everything seems to be back to normal. - Applied the pacth 14; - Searched for the files, found one file called Docs.js with some injection code on it, cleanned; - A problem with DKIM and ipv6 after the patch; - Renew all the keys and passwords. The opendkim issue I sol...

Two days ago I was attacked by this bitcoin stuff. Did every step necessary, patched the software, followed a lot of instructions... Currently, my zmopendkimctl is not running and the zmconfigd always seems to fail on start but later it's working. First-time I'm facing something like this. Best rega...
