  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
