linux中postfix配置安装

 　　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,yum install postfix system-switch-mail,　　设定postfix,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 = $mydestination,　　开机启动,vi /etc/rc.d/rc.local,/usr/sbin/postfix start,　　安装与设定dovecot (Centos6.4),　　安装软体,yum -y install dovecot cp /etc/dovecot.conf /etc/dovecot.conf.bak vi /etc/dovecot.conf,protocols = pop3 ssl_disable = yes,　　修改dovecot收信预设位置,vi /etc/dovecot/conf.d/10-mail.conf,mail_location = mbox:~/mail:INBOX=/var/mail/%u,vi /etc/dovecot/conf.d/10-auth.conf,disable_plaintext_auth = no auth_mechanisms = plain login,　　重新启动,　　设定postfix SMTP 验证,vi /etc/postfix/main.cf,smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination,chkconfig saslauthd on  service saslauthd restart   ,　　病毒过滤软体 Amavisd + Clamav 防毒与垃圾信,　　安装clamav amavisd-new软体,yum -y install clamav amavisd-new,service clamd start,chkconfig --level 3,5 freshclam on,service amavisd start,chkconfig --level 3,5 amavisd on,　　指定邮件伺服器网域,vi /etc/amavisd/amavisd.conf,$mydomain = www.111cn.net  ,　　在 master.cf 中先定义一个病毒过滤服务,vi /etc/postfix/master.cf,amavis unix - - - - 2 smtp -o smtp_data_done_timeout=1200,　　再加入底下几行设定,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,
