Install zimbra mail server on ubuntu 20.04

1. It is strongly recommended that you use Ubuntu LTS. Installing a complex server software like Zimbra on a non-LTS Ubuntu is discouraged, as you will likely run into problems if you upgrade your OS every nine months. Keeping your mail server stable for 2 or 5 years is much better.

2. Zimbra must be installed on a clean, new server.

if your not local, please edit your webhosting dns settings and create the MX Records.
