1.如果CentOS下已经安装sendmail，先将sendmail卸载

/etc/init.d/sendmail stop

rpm -qa | grep sendmail

rpm -e sendmail

2.安装postfix

yum -y install postfix//yum会自动将cyrus-sasl2安装上

vim /etc/postfix/main.cf

修改内容如下：

myhostname = mail.test.com

mydomain = test.com

myorigin = $mydomain

inet_interfaces = all

mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain,

mail.$mydomain, www.$mydomain, ftp.$mydomain

mynetworks_style = subnet

mynetworks = 127.0.0.0/8, localhost, 10.0.0.0/8

relay_domains = $mydestination

home_mailbox = Maildir/ //如果采用系统帐号作为邮件用户名，该目录为帐号下的目录

最后面添加（sasl加密算法支持）

smtpd_sasl_auth_enable = yes

smtpd_sasl_security_options = noanonymous

broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_sasl_authenticated,reject_unauth_destination,permit_mynetworks

smtpd_client_restrictions = permit_sasl_authenticated

3.配置sasl

vi /usr/lib/sasl2/smtpd.conf

内容如下：

pwcheck_method: saslauthd
mech_list: PLAIN LOGIN
log_level:3
saslauthd_path: /var/run/saslauthd/mux

vi /etc/sysconfig/saslauthd

修改：

MECH=shadow //使用系统用户进行认证

4.设置开机启动postfix和sasl

chkconfig postfix on

chkconfig saslauthd on

5.启动postfix和sasl

service postfix start

service saslauthd start

6.验证postfix的认证

1. /usr/sbin/testsaslauthd -u root -p 123456 -s smtp
