如果需要配置DNS,可以参考： [url]http://panyongzheng.iteye.com/blog/1882011[/url]

[color=red][b]注意：重启，要检查resolv.conf问题[/b][/color]

[b][size=large][color=red]关闭/禁用SELinux[/color][/size][/b]
sudo gedit /etc/selinux/config
修改成 SELINUX=disable 禁用SeLinux；修改成 SELINUX=enforcing 使用SeLinux
[color=red]主意，这个会引起后面的第6个问题。[/color]

CentOS安装扩展:
[color=darkblue]sudo yum install gcc kernel-devel kernel-headers dkms make bzip2 perl[/color]

[b][color=red]配置iptables:[/color][/b]
[color=darkblue]sudo gedit /etc/sysconfig/iptables[/color]
-A INPUT -m state --state NEW -m tcp -p tcp --dport 25 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 53 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 110 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 1024 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 1025 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 4190 -j ACCEPT
[color=darkblue]sudo service iptables restart[/color]

[color=red][b]软件安装：[/b][/color]
[color=darkblue]sudo yum -y install telnet
sudo yum -y install postfix* dovecot*
sudo yum -y install httpd mysql mysql-server mysql-devel php php-mysql
sudo yum -y install php-mbstring php-imap php-xml
sudo yum install pam-devel
或者:
sudo yum -y install telnet postfix* dovecot* httpd mysql mysql-server mysql-devel php php-mysql php-mbstring php-imap php-xml pam-devel
sudo chkconfig postfix on
sudo chkconfig dovecot on
sudo chkconfig httpd on
sudo chkconfig mysqld on
sudo gedit /etc/httpd/conf/httpd.conf //找到#ServerName www.example.com:80 把#去掉
sudo service postfix restart
sudo service dovecot restart
sudo service httpd restart
sudo service mysqld restart [/color]
[color=red]注意:以上自动开机运行和启动服务很重要，否则可能会碰到乱七八糟的问题[/color]

[color=red][b]创建一个vmail用户[/b][/color]，用作管理虚拟邮箱的文件夹
[color=darkblue]sudo useradd -u 2000 -d /var/vmail -m -s /sbin/nologin vmail[/color]

[color=red][b]创建mail数据库和账户[/b][/color]：
mysqladmin -uroot password 'root'
mysql -h localhost -uroot -p
mysql> GRANT ALL PRIVILEGES ON mail.* TO root@localhost IDENTIFIED BY 'root';
mysql> create database mail;
mysql> GRANT ALL PRIVILEGES ON mail.* TO admin@"localhost" IDENTIFIED BY '123123' WITH GRANT OPTION;
mysql> flush privileges;

[color=red][b]下载postfixadmin:[/b][/color]
[url]http://sourceforge.net/projects/postfixadmin/files/postfixadmin/postfixadmin-2.3.6/postfixadmin-2.3.6.tar.gz/download[/url]
解压，并重命名：postfixadmin，复制到/var/www/html
[color=darkblue]sudo cp -rf /home/pandy/下载/postfixadmin /var/www/html[/color]

[color=red][b]修改postfixadmin配置文件:[/b][/color]
[color=darkblue]sudo gedit /var/www/html/postfixadmin/config.inc.php[/color]
------------
[color=darkblue]$CONF['configured'] = true;
$CONF['default_language'] = 'cn';
$CONF['database_type'] = 'mysql';
$CONF['database_host'] = 'localhost';
$CONF['database_user'] = 'admin';
$CONF['database_password'] = '123123';
$CONF['database_name'] = 'mail';
$CONF['admin_email'] = 'admin@pandy8.com';
$CONF['encrypt'] = 'dovecot:CRAM-MD5';
$CONF['dovecotpw'] = "/usr/bin/doveadm pw";
$CONF['domain_path'] = 'YES';
$CONF['domain_in_mailbox'] = 'NO';
$CONF['aliases'] = '1000';
$CONF['mailboxes'] = '1000';
$CONF['maxquota'] = '1000';
$CONF['fetchmail'] = 'NO';
$CONF['emailcheck_resolve_domain']='NO';
$CONF['quota'] = 'YES';
$CONF['used_quotas'] = 'YES';
$CONF['new_quota_table'] = 'YES';[/color]

[color=red][b]进入postfixadmin:[/b][/color]
[url]http://127.0.0.1/postfixadmin/setup.php[/url]
输入:admin / admin, generate password hash, 跳转到第二部，得到一个hash code,
复制这个code,并修改：sudo gedit /var/www/html/postfixadmin/config.inc.php
$CONF['setup_password'] = 'ae3e1cb27c62fae6c43dc1fd84853207:03bf21e651640880b910317a27fdb205fe8949fa'; //这个值是根据你的输入变化的
然后继续其他设定，[color=red][b]注意，先不创建管理员账户，以后再创建。[/b][/color]

[color=red][b]postfixadmin[/b][/color]
=================================
[color=red][b]postfxiadmin不能自动创建目录，增加自动建立目录的功能[/b][/color]
建立创建虚拟邮箱脚本，脚本名称 /usr/local/bin/maildir-creation.sh ，脚本内容如下：
[color=darkblue]sudo gedit /usr/local/bin/maildir-creation.sh[/color]
--------------------------------------------
[color=darkblue]#!/bin/bash
HOME_DIR="/var/vmail"
USER_NAME="vmail"
GROUP_NAME="vmail"
if [ ! -d ${HOME_DIR}/$1 ] ; then
mkdir ${HOME_DIR}/$1
chown -R ${USER_NAME}.${GROUP_NAME} ${HOME_DIR}/$1
fi
mkdir ${HOME_DIR}/$1/$2
chown -R ${USER_NAME}.${GROUP_NAME} ${HOME_DIR}/$1/$2[/color]

建立删除虚拟邮箱脚本，脚本名称 /usr/local/bin/maildir-deletion.sh ,脚本内容如下：
[color=darkblue]sudo gedit /usr/local/bin/maildir-deletion.sh[/color]
----------------------------------------------
[color=darkblue]#!/bin/bash
#
# vmta ALL = NOPASSWD: /usr/local/bin/maildir-deletion.sh
#
if [ $# -ne 2 ] ; then
exit 127
fi
DOMAIN="$1"
USER="$2"
HOME_DIR="/var/vmail"
USER_DIR="${HOME_DIR}/${DOMAIN}/${USER}"
TRASH_DIR="${HOME_DIR}/deleted-maildirs"
DATE=`date "+%Y%m%d_%H%M%S"`
if [ ! -d "${TRASH_DIR}/${DOMAIN}" ] ; then
mkdir -p "${TRASH_DIR}/${DOMAIN}"
fi
if [ -d "${USER_DIR}" ] ; then
mv ${USER_DIR} ${TRASH_DIR}/${DOMAIN}/${USER}-${DATE}
fi[/color]

建立删除目录
[color=darkblue]sudo mkdir /var/vmail/deleted-maildirs
sudo chown -R vmail.vmail /var/vmail/deleted-maildirs/[/color]

赋予脚本可执行权限
[color=darkblue]sudo chmod 750 /usr/local/bin/maildir-*
sudo chown vmail.vmail /usr/local/bin/maildir-*[/color]

配置sudo
在 /etc/sudoers 增加一行
[color=darkblue]sudo vim /etc/sudoers[/color]
----------------------------
vmail ALL = NOPASSWD: /usr/local/bin/maildir-creation.sh
vmail ALL = NOPASSWD: /usr/local/bin/maildir-deletion.sh
注释掉下面内容
#Defaults requiretty
esc , :wq!, 强制保存

[color=darkblue][b]修改postfixadmin的相关文件[/b][/color]
修改[color=red]create-mailbox.php[/color] 文件，229行内容应该是：
[color=darkblue]sudo gedit /var/www/html/postfixadmin/create-mailbox.php[/color]
db_log ($SESSID_USERNAME, $fDomain, 'create_mailbox', "$fUsername");
在该行前面增加下面一行：
[color=darkblue]system("sudo /usr/local/bin/maildir-creation.sh $fDomain ".$_POST['fUsername']);[/color]

修改[color=red]delete.php[/color] 文件，146行内容应该是：
[color=darkblue]sudo gedit /var/www/html/postfixadmin/delete.php[/color]
db_log ($SESSID_USERNAME, $fDomain, 'delete_mailbox', $fDelete);
在该行下面增加下面4行：
[color=darkblue]$userarray=explode("@",$fDelete);
$user=$userarray[0];
$domain=$userarray[1];
system("sudo /usr/local/bin/maildir-deletion.sh $domain $user");[/color]

[b][color=red]4、配置Postfix[/color][/b]

=========================================
[color=darkblue]修改/etc/postfix/main.cf文件[/color]：
[color=darkblue]sudo gedit /etc/postfix/main.cf[/color]
[color=red]基本配置[/color]
---------------------------------------以下修改
[color=darkblue]myhostname = bogon //这个是hostname命令得到的
mydomain = pandy8.com
myorigin = $mydomain
inet_interfaces = all
mydestination = localhost //是否需要修改成其他？无法收外网的信，即使有MX记录
#mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain //这个要注释掉?，否则出现unknown user错误。
mynetworks_style = host[/color]

[color=red]虚拟域名配置[/color]
---------------------------------------以下增加
[color=darkblue]#=======================================================================
# ADDRESS REDIRECTION (VIRTUAL DOMAIN)
#
# The VIRTUAL_README document gives information about the many forms
# of domain hosting that Postfix supports.
# See: http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu8.04-p2
# The follwing lines connect Postfix with the MySQL database that contains information about
# the virtual users/accounts hosted. See proxymap(8) virtual(5) and mysql_table(5)
#
virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql_virtual_domains_maps.cf
#
virtual_alias_maps = proxy:mysql:/etc/postfix/mysql_virtual_alias_maps.cf
#
virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf

[color=red]SMTP加密设定[/color]
---------------------------------------
[color=darkblue]#=======================================================================
#SASL SUPPORT FOR CLIENTS
#
# The following options set parameters needed by Postfix to enable
# SMTP AUTH support using Dovecot's SASL component for authentication of mail clients.
# See: /usr/share/doc/postfix-2.3.3/README_FILES/SASL_README - http://www.postfix.org/SASL_README.html
# And /usr/share/doc/dovecot-1.0.7/wiki/HowTo.PostfixAndDovecotSASL.txt - http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL
#
# Turns on sasl authorization
smtpd_sasl_auth_enable = yes
#
#Use dovecot for authentication
smtpd_sasl_type = dovecot
#
# Path to UNIX socket for SASL
smtpd_sasl_path = /var/run/dovecot/auth-client
#
#Disable anonymous login. We don't want to run an open relay for spammers.
smtpd_sasl_security_options = noanonymous
#
#Adds support for email software that doesn't follow RFC 4954.
#This includes most versions of Microsoft Outlook before 2007.
broken_sasl_auth_clients = yes
#
smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination[/color]

[color=red]使用Dovecot做为投递[/color]
---------------------------------------
[color=darkblue]#=======================================================================
# TRANSPORT MAP
#
virtual_transport = dovecot
dovecot_destination_recipient_limit = 1[/color]

[b][color=darkblue]修改master.cf文件[/color][/b]
[color=darkblue]sudo gedit /etc/postfix/master.cf[/color]
在底部增加
---------------------------------------
dovecot unix - n n - - pipe
flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient}

[color=red][b]创建Mysql脚本[/b][/color]
==================================
[color=darkblue]sudo gedit /etc/postfix/mysql_virtual_domains_maps.cf[/color]
---------------------------------------
user = admin
password = 123123
hosts = localhost
dbname = mail
query = SELECT domain FROM domain WHERE domain='%s' AND active = '1'
#optional query to use when relaying for backup MX

hosts = localhost
dbname = mail
query = SELECT quota FROM mailbox WHERE username='%s' AND active = '1'

[b][color=red]5、配置Dovecot[/color][/b]

[color=red][b]安装roundcubemail[/b][/color]
===================================
下载位置，可能要跳墙才能下载
[url]http://superb-dca2.dl.sourceforge.net/project/roundcubemail/roundcubemail/0.9.1/roundcubemail-0.9.1.tar.gz[/url]
解压，重新命名:roundcubemail,并复制到html文件夹

[color=darkblue]重新启动httpd服务:[/color]
sudo service httpd restart;

进入：[url]http://127.0.0.1/roundcubemail/[/url]
使用上面创建的:test@pandy8.com/test进入

查看收件箱，就能看到创建帐号自动发送的邮件，如果没有，那么到postfixadmin里面去尝试发送一个，就看见了。

[color=blue][b]Roundcube邮件系统的插件[/b][/color]：[url]http://trac.roundcube.net/wiki/Plugin_Repository
[b][color=red]配置managesieve插件[/color][/b]，提供过滤器，假期回复
[color=darkblue]sudo yum -y install dovecot-pigeonhole[/color]

修改/etc/dovecot/dovecot.conf文件，做如下修改：
[color=darkblue]sudo gedit /etc/dovecot/dovecot.conf[/color]
protocols = pop3 imap sieve

修改/etc/dovecot/conf.d/15-lda.conf文件，做如下修改：
[color=darkblue]sudo gedit /etc/dovecot/conf.d/15-lda.conf[/color]
mail_plugins = quota sieve

[b]重新启动dovecot[/b]
[color=darkblue]sudo service dovecot restart[/color]

[b]Dovecot监听4190端口[/b]：
[color=darkblue]netstat -tunlp | grep 4190[/color]

[img]http://img1.51cto.com/attachment/201204/140158252.png[/img]
[color=darkblue]更多插件的配置见[/color]：
Roundcube Webmail 多域及插件配置篇:[url]http://blog.dvxj.com/pandola/roundcube-webmail-plugins.html[/url]
$rcmail_config['plugins'] = array('managesieve','password','filesystem_attachments', 'emoticons', 'example_addressbook', 'message_highlight','jqueryui','globaladdressbook','userinfo','markasjunk','enigma','vcard_attachments','help');
加了6个插件，为啥是6个，因为那个jqueryui是其他插件要用的脚本，所以具体插件数目是6个，array圆括号内的参数，单引号引起来的，比如'password'，引号内的内容，一定是和plugins目录中插件目录名一致，这样Roundcube才会根据配置，加载相应的插件。
globaladdressbook:全局地址簿，这个功能其实不错，可以让域管理员统一提前配置好公司所有人的邮件地址，这样大家发邮件的时候就可以使用现成的了。当然，这个不影响每个用户自己私人的地址簿，是分开的。
[color=darkblue]sudo cp -rf /home/pandy/下载/global-address-book /var/www/html/roundcubemail/plugins/[/color]
compose_addressbook:是写邮件时，可以通过点击一个按钮，弹出窗口调出地址簿，让你选择收件人，抄送、密送等邮件地址；

[color=red][b]问题:[/b][/color]
[b]1. dovecot测试 -ERR Authentication failed[/b]

[b]2. Connection closed by foreign host[/b]
确保运行dovecot服务，sudo chkconfig postfix on ， service dovecot restart;
[url]http://www.pooy.net/connection-closed-foreign-host.html[/url]
造成这个原因是因为原来连接到SSHD服务器进程的22端口，当你的客户端突然断开时，服务器端的TCP连接就处于一个半打开状态。当下一次同一客户机再次建立 TCP连接时，服务器检测到这个半打开的TCP连接，并向客户机回传一个置位RST的TCP报文，客户机就会显示connection closed by foreign host。
这是TCP协议本身的一个保护措施，并不是什么错误，你只要再重新连接服务器就能连上。
我用的是wifi，然后登录路由之后，断网，自动的重新链接即可了！

CentOS6.4邮件配置一: postfix + dovecot + mysql + postfixadmin + Roundcubemail_网络

Roundcube Webmail 多域及插件配置篇:[url]http://blog.dvxj.com/pandola/roundcube-webmail-plugins.html
$rcmail_config['plugins'] = array('managesieve','password','filesystem_attachments', 'emoticons', 'example_addressbook', 'message_highlight','jqueryui','globaladdressbook','userinfo','markasjunk','enigma','vcard_attachments','help');
加了6个插件，为啥是6个，因为那个jqueryui是其他插件要用的脚本，所以具体插件数目是6个，array圆括号内的参数，单引号引起来的，比如'password'，引号内的内容，一定是和plugins目录中插件目录名一致，这样Roundcube才会根据配置，加载相应的插件。
globaladdressbook:全局地址簿，这个功能其实不错，可以让域管理员统一提前配置好公司所有人的邮件地址，这样大家发邮件的时候就可以使用现成的了。当然，这个不影响每个用户自己私人的地址簿，是分开的。
