1、安装系统包

使用yum安装postfix，dovecot包，启用系统服务。

yum install postfix dovecot
chkconfig postfix on
chkconfig dovecot on

2、配置main.cf文件

vi /etc/postfix/main.cf

# 修改或增加如下行
myhostname = mail.fileregion.com
mydomain = fileregion.com
myorigin = $mydomain
inet_interfaces = all
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mynetworks = 127.0.0.0/8
home_mailbox = Maildir/
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_auth_enable = yes
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, permit
broken_sasl_auth_clients = yes

重启postfix:

/etc/init.d/postfix restart
