postfix邮件服务器(debian sarge)1、简要说明
简易安装postfix邮件服务器
2.1、mail:~#apt-get install postfix
安装，根据提示选"Internet Site"
Where should mail for root go填postfix
Mail name?填mail.wjjennluen.com
Other destinations to accept mail for?(blank for none)填mail.wjjennluen.com, localhost.wjjennleun.com, ,localhost

2.2、检查postfix服务是不是已经运行
mail:~# netstat -ln|grep 25

tcp6 0 0 :::25 :::* LISTEN
unix 2 [ ACC ] STREAM LISTENING 20256 /tmp/.ICE-unix/11772
2.3、测试postfix
mail:~# telnet 127.0.0.1 25
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

mail~:#more /var/spool/mail/wxt
没有
咱回事呢

mail:~#
收到了，此时postfix工作在127.0.0.1上的,也就是localhost
查看mydestination参数的设定
mail:~# postconf |grep mydestination
mydestination = mail.wjjennluen.com, localhost.wjjennluen.com, , localhost
没有wjjennleun.com，所以用wxt@wjjennluen.com发信，postfix不会接受,所以要添加wjjennluen.com给mydestination
mail:~# postconf |grep mydestination
mydestination = mail.wjjennluen.com wjjennluen.com localhost.wjjennluen.com localhost
现在就可以收到了

mail:~#
2.5、安装pop3,imap
mail:~#apt-get install courier-pop courier-imap
注意/etc/courier/pop3d配置文件
注意/etc/courier/imapd配置文件
用outlook测试pop3和imap成功
2.6、安装apache,php,squirrelmail
mail:~#apt-get apache php4 php4-common squirrelmail
修改/etc/apache/httpd.conf
加入PHP支持
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
新建文件/var/www/test.php
phpinfo();
?
在浏览器地址栏内输入http://192.168.0.15/test.php
可以确定PHP是否可以正常工作
2.7、从mailbox 更改为maildir
修改/etc/postfix/main.cf
增加参数设置
home_mailbox = Maildir/
更改mailbox_command 参数为
mailbox_command = /usr/bin/procmail -a "$EXTENSION" DEFAULT=$HOME/Maildir/
新增
MAILDIR=$HOME/Maildir
mail:~#cd /home/wxt/
mail:~#maildirmake Maildir
mail:~#chmod -R 750 Maildir
mail:~#ln -s /usr/share/squirrelmail /var/www/squirrelmail
修改/usr/share/squirrelmail/config/conf.pl内的变量$auto_create_special = ture;，让squirrelmail自动增加三个子目录
添加webmail虚拟主机(基于名子)
打开/etc/apache/httpd.conf
添加虚拟主机配置参数
NameVirtualHost 192.168.0.15
ServerAdmin root@localhost
DocumentRoot /var/www/squirrelmail
ServerName webmail.wjjennluen.com
ErrorLog /var/log/apache/webmail/error.log
mail:~#makdir /var/log/apache/webmail
mail:~#touch /var/log/apache/webmail/error.log
注意在named配置文件里面加入webmail.wjjennluen.com的记录
在浏览器的地址栏内输入webmail.wjjennluen.com就可以登陆webmail了
2.7、给postfix 加上smtp 认证
mail:~# apt-get install postfix-tls sasl2-bin libsasl2-modules
修改/etc/default/saslauthd文件,设定START = yes
修改/etc/postfix/sasl/smtpd.conf,设定saslauthd来认证smtp
mail:~#mkdir /etc/postfix/sasl
mail:~#echo "pwcheck_method: saslauthd" /etc/postfix/sasl/smtpd.con
添加帐户postfix到sasl组
mail:~#addgroup postfix sasl
修改/etc/postfix/main.cf, 使postfix使用sasl来实现smtp验证功能
#=====sasl======#
smtpd_sasl_auth_enable = yes
broken_sasl_auth_clients = yes
smtpd_sasl_security_options = noanonymous
smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, check_relay_domains, reject_unauth_destination
smtpd_client_restrictions = permit_sasl_authenticated
修改/etc/postfix/master.cf,让postfix不要以chroot启动,参数-v可以用来debug,正式上线为了不使大量的log，一定要拿掉
# ==============================================
# service type private unpriv chroot wakeup maxproc command + args
# (yes) (yes) (yes) (never) (100)
# ==============================================
smtp inet n - n - - smtpd -v
重新启动sasl 验证程序
mail:~# /etc/init.d/saslauthd restart
重新启动postfix
mail:~#/etc/init.d/postfix restart
mail:~# testsaslauthd -u wxt -p wxt
0: OK "Success."
测试sasl验证程序可以正常工作了
