    Hello Matei,

    First of all thank you for your tutorial, i tried to install this setup on CentOS 7 several times, but every-time i can not open the admin portal on 7071? all services are running, but i can not see that zimbra is listening on the port, any expirience on such problems?

    Best regards,

      What’s the output of netstat -tlpn command? Can you see Zimbra ports listening on your network interfaces IP addresses? To open firewall port use the following command:
      firewall-cmd –add-port=7071/tcp –permanent
      firewall-cmd –reload

      Or try to disable the firewall for a while and check if you can connect to zimbra port from brwoser:
      systemctl stop firewalld

    I am looking for a help to install zimbra mail server configurations on centos 6.5 32 bit

    Excellent article. Everything went smooth during install. However when I tried to access on the browser I get nothing, just a browser message that the site cannot be reached. I have pinged by ip and hostname and both ping ok. I have tried to browse by both too and no luck. Obviously I am missing something.

    how to setup mx records for my domain with examples thank you

    • Matei Cezar says:

      Setting up an A record, a MX or SPF record highly depends on your domain name registrar or ISP who provides the DNS service. Pay a great deal of attention to these types of DNS records on a public domain name because your mail servers can be abused by spammers or you”ll end-up in a spam blacklist.

  9. Matei Cezar says:

    Run ss command to get a list of all network sockets and verify if zimbra is listening on the following ports: 443 and 7071 . Any errors on logs? Supply more info!
