How to Install Zimbra 8.6.0 on RHEL 7/CentOS 7

Zimbra 8.6.0 brings new features, improvements in Mail server and better web clients experience. Some that caught my attention was local lmtp client can communicate over ssl for mail server, better organization of shared folders for web client and the calendar now can run search on description for location or resources. You can get detailed information on this Release Notes. In this article, I will explain step by step how to install Zimbra 8.6.0 on RHEL 7 or CentOS 7.
