I wrote a small script for installing mail server on centminmod. The script supports only Centos 7. Just download the script from https://github.com/Brijendrasial/CentMinMod_MailServer/blob/master/CMM_Email.sh
How to use it:
git clone https://github.com/Brijendrasial/CentMinMod_MailServer.git
cd CentMinMod_MailServer
chmod 0777 CMM_Email.sh
./CMM_Email.sh
#!/bin/bash
