postfix是Wietse Venema在IBM的GPL協議之下開發的MTA(郵件傳輸代理)軟件。postfix是Wietse Venema想要為使用最廣泛的sendmail提供替代品的一個嘗試,下面我們來看看postfix配置安裝方法。
安裝Postfix
代碼如下yum install postfix system-switch-mail
設定postfix
代碼如下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
開機啟動
代碼如下vi /etc/rc.d/rc.local
/usr/sbin/postfix start
安裝與設定dovecot (Centos6.4)
安裝軟體
代碼如下yum -y install dovecot
cp /etc/dovecot.conf /etc/dovecot.conf.bak
vi /etc/dovecot.conf
protocols = pop3
ssl_disable = yes
修改dovecot收信預設位置
代碼如下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
重新啟動
代碼如下 service dovecot restart設定postfix SMTP 驗證
代碼如下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
病毒過濾軟體 Amavisd + Clamav 防毒與垃圾信
安裝clamav amavisd-new軟體
代碼如下yum -y install clamav amavisd-new
service clamd start
chkconfig --level 3,5 freshclam on
service amavisd start
chkconfig --level 3,5 amavisd on
指定郵件伺服器網域
代碼如下vi /etc/amavisd/amavisd.conf
$mydomain = www.111cn.net
在 master.cf 中先定義一個病毒過濾服務
代碼如下vi /etc/postfix/master.cf
amavis unix - - - - 2 smtp -o smtp_data_done_timeout=1200
再加入底下幾行設定
代碼如下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
