Zimbra mail server installation and configuration RHEL7 / Centos 7

Zimbra mail server is an free email server for open source users, which will provide calender and collaboration solution. Zimbra mail server has GUI interface to manage administrator console.
The Zimbra Collaboration includes the Zimbra MTA, the Zimbra LDAP server, and the Zimbra mailbox server. In a single-server installation, all components are installed on one server and require no additional manual configuration. This installation guide is a quick start guide that describes the basic steps needed to install and configure Zimbra Collaboration in a direct network connect environment.

In this environment, the Zimbra server is assigned a domain for which it receives mail, and a direct network connection to the Internet. When Zimbra Collaboration is installed, you will be able to log on to the Zimbra administration console to manage the domain and provision accounts.
In this tutorial / article we will explain how to install and configure zimbra mail server in RHEL 7.x / Centos 7.x. Before going to install we have to complete prerequisites as mentioned below.
  1. Stop sendmail and postfix
  2. Add MX record in DNS
  3. Add A (Authoritative Record) in Forward and reverse lookup zones
  4. Add entry in /etc/hosts
  5. Enable ports in zimbra mail server

Stop sendmail and postfix services to stop port conflict with zimbra

Stop postfix and sendmail services to avoid port conflicts. Mask the service so that if anybody unfortunately  try to start also service will not start.
[root@mail ~]# systemctl stop postfix.service
[root@mail ~]# systemctl stop sendmail
[root@mail ~]# systemctl mask postfix.service
[root@mail ~]# systemctl mask sendmail

Adding MX Record in IPA Server DNS

[root@ipaserver ~]# kinit admin
[root@ipaserver ~]# ipa dnsrecord-add arkit.co.in @ --mx-rec="9 mail.arkit.co.in."
[root@ipaserver ~]# dig mail.arkit.co.in MX

Adding A and PTR records in DNS

Edit your DNS zone configuration files and add entry like mentioned below
1w MX 9 mail.arkit.co.in.

Adding /etc/hosts entry

[root@mail ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
192.168.4.29 mail.arkit.co.in mail
#::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
