01-17

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 restart
chkconfig 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
