第二步：（实现web端的收发，以及支持mysql端虚拟用户的收发，密码的修改等）
1.环境配置
yum install httpd mysql mysql-devel mysql-server php php-pecl-Fileinfo php-mcrypt php-devel php-mysql php-common php-mbstring php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc pcre pcre-devel
# vi /etc/httpd/conf/httpd.conf
#增加下面两行
AddType application/x-httpd-php .php
PHPIniDir "/etc/php.ini"
#修改下面四行
DirectoryIndex index.php index.html index.html.var
User vmail
Group vmail
Listen 9999（为了测试方便，端口号未修改）
# vi /var/www/html/index.php
<?php phpinfo();?>
# systemctl start httpd.service
浏览器输入
http://110.110.110.110:9999/即可测试成功
2.配置postfixadmin
# tar -zxvf postfixadmin-2.93.tar.gz -C /var/www/html
# cd /var/www/html
# mv postfixadmin-2.93 postfixadmin
# vi postfixadmin/config.inc.php
$CONF['configured'] = true;
$CONF['setup_password'] = 'afe0c247277cb58f7ccf798da29b0976:8744abeb23a481eb0fc14a8f9286da0827352d02';
$CONF['database_type'] = 'mysql';
$CONF['database_host'] = 'localhost';
$CONF['database_user'] = 'postfix';
$CONF['database_password'] = 'postfix';
$CONF['database_name'] = 'postfix';
$CONF['admin_email'] = 'wc@free.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['quota'] = 'YES';
$CONF['used_quotas'] = 'YES';
$CONF['new_quota_table'] = 'YES';
3.配置mysql
systemctl start mariadb.service
mysql
mysql> create database postfix;
mysql> grant all on postfix.* to postfix@'localhost' identified by 'postfix';
mysql> flush privileges;
# mysql -u postfix -p postfix
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| postfix |
| test |
+--------------------+
3 rows in set (0.00 sec)
mysql>
4.浏览器验证
# chown -R vmail.vmail postfixadmin/
http://110.110.110.110/postfixadmin/setup.php
如果报错说没有dovecot安装即可
yum install dovecot dovecot-devel dovecot-mysql
http://110.110.110.110/postfixadmin/login.php能登录即可
5.postfxiadmin不能自动创建目录，所以我们得增加自动建立目录的功能
5.1建立创建虚拟邮箱脚本
# vim /usr/local/bin/maildir-creation.sh
#!/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
5.2建立删除虚拟邮箱脚本
# vim /usr/local/bin/maildir-deletion.sh
#!/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
5.3手动建立目录及赋予权限
# mkdir /var/vmail/deleted-maildirs
# chown -R vmail.vmail /var/vmail/deleted-maildirs/
# chmod 750 /usr/local/bin/maildir-*
# chown vmail.vmail /usr/local/bin/maildir-*
#vim /etc/sudoers
#文本最后增加两行
vmail ALL = NOPASSWD: /usr/local/bin/maildir-creation.sh
vmail ALL = NOPASSWD: /usr/local/bin/maildir-deletion.sh
#修改下面一行
#Defaults requiretty
：wq! #由于这个文件是只读的，所以得强制保存并退出
5.4未找到的内容，参考文献上有，本人并未配置（任然需要测试）
# cd /var/www/html/postfixadmin/
# vim create-mailbox.php
修改create-mailbox.php 文件，229行内容应该是：
db_log ($SESSID_USERNAME, $fDomain, 'create_mailbox', "$fUsername");
在该行前面增加下面一行,
system("sudo /usr/local/bin/maildir-creation.sh $fDomain ".$_POST['fUsername']);
# vim delete.php
修改delete.php 文件，146行内容应该是,
db_log ($SESSID_USERNAME, $fDomain, 'delete_mailbox', $fDelete);
在该行下面增加下面4行,
$userarray=explode("@",$fDelete);
$user=$userarray[0];
$domain=$userarray[1];
system("sudo /usr/local/bin/maildir-deletion.sh $domain $user");

报错1：浏览器输入http://110.110.110.110/postfixadmin/setup.php报错如下
Error: Smarty template compile directory templates_c is not writable
解决1：目录权限问题，chown -R vmail.vmail postfixadmin执行即可
报错2：Setup password not specified correctly
解决2：
报错3：Your password must contain at least 2 digit(s).
解决3：
报错4：浏览器执行http://110.110.110.110:110/postfixadmin/login.php输入管理员账号密码无用
tail -f /var/log/httpd/error_log
[Thu Dec 31 15:40:43.373654 2015] [:error] [pid 2916] [client 175.175.175.175:52509] PHP Warning: session_start(): open(/var/lib/php/session/sess_1pg175mspao175iebqcfmhu0b6, O_RDWR) failed: Permission denied (13) in /var/www/html/postfixadmin/common.php on line 30, referer: http://110.110.110.110:110/postfixadmin/login.php
解决4：cd /var/lib/php之后执行chown -R vmail.vmail session即可
错误4：和网上说的vi /etc/php.ini中去掉session.save_path ='/tmp'前的;无关
