Setup A Local Mail Server In CentOS 7

You are here

Introduction

This tutorial describes how to setup a local mail server using Postfix, Dovecot And Squirrelmail in CentOS 7. Please note that I said “local mail server”. This tutorial doesn’t help you if you want to send or receive mails to outside like Gmail or yahoo. However, if you want send/receive mails to outside, you should configure the mail server with a public IP, and request your ISP to configure the MX record of your mail server in their DNS server.

I tested this setup on CentOS 64 bit server. Although, the same steps should work on RHEL and Scientific Linux 7 distributions. My test box details are given below:

    OS: CentOS 7 64bit minimal server
    IP Address: 192.168.1.150/24
    Hostname: server1.unixmen.local

Let us get started now.
