postfix是Wietse Venema在IBM的GPL协议之下开发的MTA(邮件传输代理)软件。postfix是Wietse Venema想要为使用最广泛的sendmail提供替代品的一个尝试,下面我们来看看postfix配置安装方法。
安装Postfix
代码如下yum install postfix system-switch-mail
设定postfix
代码如下vi /etc/postfix/main.cf
myhostname = ha.xxx.kh.edu.tw
myorigin = $myhostname
myorigin= xxx.kh.edu.tw
inet_interfaces = all
#inet_interfaces = local
mydestination = $myhostname, localhost.$mydomain, localhost
mynetworks = 163.32.X.0/24, 127.0.0.0/8
relay_domains = $mydestination
开机启动
代码如下vi /etc/rc.d/rc.local
/usr/sbin/postfix start
安装与设定dovecot (Centos6.4)
安装软体
代码如下yum -y install dovecot
cp /etc/dovecot.conf /etc/dovecot.conf.bak
vi /etc/dovecot.conf
protocols = pop3
ssl_disable = yes
修改dovecot收信预设位置
代码如下vi /etc/dovecot/conf.d/10-mail.conf
mail_location = mbox:~/mail:INBOX=/var/mail/%u
vi /etc/dovecot/conf.d/10-auth.conf
disable_plaintext_auth = no
auth_mechanisms = plain login
重新启动
代码如下 service dovecot restartchkconfig dovecot on
设定postfix SMTP 验证
代码如下vi /etc/postfix/main.cf
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination
chkconfig saslauthd on
service saslauthd restart
病毒过滤软体 Amavisd + Clamav 防毒与垃圾信
安装clamav amavisd-new软体
代码如下yum -y install clamav amavisd-new
service clamd start
chkconfig --level 3,5 freshclam on
service amavisd start
chkconfig --level 3,5 amavisd on
指定邮件伺服器网域
代码如下vi /etc/amavisd/amavisd.conf
$mydomain =www.111cn.net
在 master.cf 中先定义一个病毒过滤服务
代码如下vi /etc/postfix/master.cf
amavis unix - - - - 2 smtp -o smtp_data_done_timeout=1200
再加入底下几行设定
代码如下127.0.0.1:10025 inet n - - - - smtpd
-o content_filter=
-o local_recipient_maps=
-o relay_recipient_maps=
-o smtpd_restriction_classes=
-o smtpd_client_restrictions=
-o smtpd_helo_restrictions=
-o smtpd_sender_restrictions=
-o smtpd_recipient_restrictions=permit_mynetworks,reject
-o mynetworks=127.0.0.0/8
-o strict_rfc821_envelopes=yes
-o smtpd_error_sleep_time=0
-o smtpd_soft_error_limit=1001
-o smtpd_hard_error_limit=1000
content_filter 参数设定
vi /etc/postfix/main.cf
content_filter = amavis:[127.0.0.1]:10024
smtp inet ............中间栏位不用修改............. smtpd
