Steps for installing ExtMail in Centos 6.4

Original intention: During the nagios test, QQ Enterprise Post Office rejected the request directly (only the records can be viewed), and 163 mailbox received the message in time (I thought my nagios configuration was wrong ), to solve the above two problems, I decided to configure a post office system by myself.
