IV. CONFIGURING LOCAL DNS SERVER

Estimated time : 3 minutes

Zimbra need an A & MX records that pointing to it’s IP Address. We could use/modify existing DNS records to meet with our requirement but I would prefer to installing local DNS server for it’s flexibility. If you’re currently using an existing & running mail server and need to replace it with Zimbra, you should not change any MX entry before completing and testing the configuration. Incomplete configuration on production mail server may impact to bounce mail, so, we need a local DNS server to prevent the impact and to do a full test before activating mail server for production use.

Setting up a DNS server on openSUSE for Zimbra requirement should be easy by using YAST. Below is a step by step, please change the IP and host name to meet with your environment on previous tutorial.

  1. Type : yast dns-server on the console/terminal
  2. Click Next on first configuration wizard : Forwarder Listzimbra-opensuse112-17

    DNS Server wizard : Initial Windows

  3. Add a new Zone. Typing your domain name on Zone name, choose Masteron type of zone and then click Add (ALT+A)zimbra-opensuse112-18

Fill in mail as Zimbra host name (see your configuration on first tutorial) on Address option, Give it a priority number (lower means highest priority) and then Press ALT+A to add MX records. Again, YAST will be smart enough to autocompleting the entry and give a fully qualified domain name to the MX records

Still on the final tab (Records), create the second Address Records for Zimbra hostname. Type mail on Record key, choose A (Address Records) as records type and write Zimbra IP on records value and then press ALT+A to add the mail Address Records
