Broken /etc/hosts

[mevets]

When I tried to install Zimbra Open Source edition from the binaries it told me that my /etc/hosts was missing things

ERROR: Installation can not proceeed.  Please fix your /etc/hosts file
  to contain:

    

  Where  is the ip address of the host, 
   is the FULLY QUALIFIED host name, and
   is the (optional) hostname-only portion

This is the contents of my /etc/hosts file

127.0.0.1	localhost
127.0.1.1	steve-laptop

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

I can't understand what I should add. Does anyone know what is necessary for me to add in order for the install to succeed?

Welcome to the forums.

You should have a look at the Quick Start Guide, installation requirements are documented there and lots of threads in the forum cover this.

You need to have DNS A & MX records pointing to your server and your hosts file needs to be:

127.0.0.1	localhost.localdomain localhost
x.x.x.x       mail.yourdomain.com mail

Where x.x.x.x is your LAN IP & mail.yourdomain.com is the FQDN of your Zimbra server.
