mail            IN A            192.168.18.152
a.com.        IN MX 10        mail.a.com.
修改本机名
2 先停sendmail
chkconfig --level 345 sendmail off
3 安装cyrus-sasl-2
 改/etc/sysconfig/saslauthd中

ps aux|grep saslauthd
/etc/init.d/saslauthd start
chkconfig --level 345 saslauthd on
4 安装postfix改配置

配置/etc/postfix/main.cf
==============================
#修改
myhostname = mail.gdvcp.net
mydomain = gdvcp.net
myorigin = $mydomain
inet_interfaces = all
mydestination = $mydomain,$myhostname
mynetworks = 192.168.18.0/24
relay_domain = gdvcp.net
#追加
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = ''
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
broken_sasl_auth_clients = yes
smtpd_client_restrictions = permit_sasl_authenticated
smtpd_sasl_security_options = noanonymous
==============================

/etc/init.d/postfix start
chkconfig --level 345 postfix
用telnet  mail.abc.com 25 测试
 ehlo abc.com
