    2. For machines ethernet / public IP it should contain FQDN, followed by hostname, followed by other aliases. For example zimbratest lab320-pc9 mfsmaster
  5. Ensure that DNS entry for FQDN resolves to machine's IP. Further MX record for email domain should resolve to Zimbra server FQDN directly or through CNAME.
  6. Create folder /opt/zimbra. Mount partitons/folder in which you want to install zimbra to /opt/zimbra. This step is required only if you want all Zimbra files to go to separate partition and not to / or /opt.
  7. Use 'yum -y install nc libaio sysstat' to install required packages
  8. Go to extracted folder and use './' from root user
  9. Enter 'Y' for agreeing with terms of service

  15. Enter new correct domain name such as
  16. This would bring setup to Zimbra configuration menu. Only admin password needs to be configured rest all can be left as it is for basic setup. To configure admin password use menu option '3' followed by '4'. Set appropriate admin password.
  17. Press 'r' to return to previous menu and then 'a' for applying configuration

  24. Now zimbra admin interface can be accessed at https://<FQDN>:7071/ and mail can be checked using web interface at https://<FQDN>/

Relaying mails through other MTA

If test system does not has access to internet then mails can be relayed through other MTA which has access to Internet (Similar to SMART_HOST for sendmail). To configure relay MTA

  1. Login in to zimbra administrative console at https://<IP>:7071/ with user admin
  2. Go to Configuration -> Global Settings -> MTA
  3. Set relay MTA for external delivery appropriately.

Stopping and starting zimbra

  1. Login as root
  2. Use 'su - zimbra'
  3. Use 'zmcontrol' command to check zimbra status, start or stop it.

Firewall configuration

Zimbra firewall configuration can be learned from

Changing Zimbra http port

We can change zimbra http port using:

  1. su - zimbra
  2. zmprov ms server.domain.tld zimbraMailPort <http_port> zimbraMailSSLPort <SSL_port>
  3. zmmailboxctld restart


  • This does not seems to work for HTTPS port


If you want to store zimbra on mooseFS then storing entire /opt/zimbra on mooseFS will not work. Specially keeping /opt/zimbra/data on moosefs does not works. Hence directories /opt/zimbra/db, /opt/zimbra/index and /opt/zimbra/store can be shifted to other filesystems to preserve space / improve filesystem performance.
