1.安裝mysql 4.1.11
# groupadd mysql
# useradd -g mysql mysql
# wget http://dev.mysql.com/get/Downloads/MySQL-4.1/mysql-4.1.11.tar.gz/from/http://mysql.new21.com/
# tar -zxvf mysql-4.1.11.tar.gz
# cd mysql-4.1.11
# ./configure --prefix=/usr/local/mysql --with-charset=gbk
# make
# make install
# cp support-files/my-medium.cnf /etc/my.cnf

設(shè)置自啟動
# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
# chmod 700 /etc/rc.d/init.d/mysqld
# chkconfig --add mysqld

安裝完以后要初始化數(shù)據(jù)庫，要是升級安裝的請?zhí)^
# cd /usr/local/mysql
# /usr/local/mysql/bin/mysql_install_db --user=mysql
# chown -R root .
# chown -R mysql var
# chgrp -R mysql .
# /usr/local/mysql/bin/mysqld_safe --user=mysql &

好了，至此mysql安裝完畢，你可以這樣起動你的mysql服務(wù)
# /etc/rc.d/init.d/mysqld start

# ln -s /usr/local/mysql/bin/mysql /sbin/mysql
# ln -s /usr/local/mysql/bin/mysqladmin /sbin/mysqladmin

為了能讓系統(tǒng)找到mysql，請運行如下命令
# PATH=$PATH:/usr/local/mysql/bin
# export PATH
# echo "/usr/local/mysql/lib/mysql" >;>; /etc/ld.so.conf
# ldconfig

日志管理
開啟錯誤日志（在[safe_mysqld]項下添加）
# vi /etc/my.cnf
[safe_mysqld]
err-log=/var/log/mysqld/err.log

開啟常規(guī)日志和更新日志 (在[mysqld]項下添加）
# vi /etc/my.cnf
[mysqld]
log=/var/log/mysqld/log.log
log-update=/var/log/mysqld/update.log

創(chuàng)建日志文件并設(shè)置權(quán)限
# mkdir /var/log/mysqld
# touch /var/log/mysqld/err.log /var/log/mysqld/log.log /var/log/mysqld/update.log
# chown -R mysql.mysql /var/log/mysqld

# service mysqld restart

說明：
錯誤日志包含了服務(wù)器寫入標(biāo)準(zhǔn)錯誤輸出設(shè)備的所有消息，同時還包括了mysql服務(wù)的啟動和關(guān)閉事件
常規(guī)日志用來記錄有關(guān)mysql服務(wù)器運行的常規(guī)信息，包括用戶的連接、查詢及其他各種時間
更新日志用來記錄修改數(shù)據(jù)庫的查詢信息，包括所有涉及數(shù)據(jù)庫修改的SQl語句的查詢記錄
建議調(diào)試結(jié)束后關(guān)閉日志

Go to top.

2.安裝apache 2.0.54
# wget http://apache.freelamp.com/httpd/httpd-2.0.54.tar.bz2
# tar jxvf httpd-2.0.54.tar.bz2
# cd httpd-2.0.54
# ./configure --prefix=/usr/local/apache
# make
# make install

設(shè)置自啟動
# cp support/apachectl /etc/init.d/httpd

修改/etc/init.d/httpd
# vi /etc/init.d/httpd(在第兩行之后添加如下內(nèi)容)
#!/bin/sh
#
# Startup script for the Apache Web Server
# chkconfig: - 85 15
# description: Apache is a World Wide Web server. It is used to serve \
# HTML files and CGI.
# processname: httpd
# pidfile: /usr/local/apache/log/httpd.pid
# config: /usr/local/apache/conf/httpd.conf

# chkconfig --add httpd
# chmod 755 /etc/init.d/httpd
# chkconfig httpd on

創(chuàng)建網(wǎng)頁根目錄
# mkdir /var/www

# vi /usr/local/apache/conf/httpd.conf
//存放網(wǎng)頁的目錄,原來為DocumentRoot ""，改成：
DocumentRoot "/var/www"
//這句應(yīng)該和DocumentRoot 的目錄保持一致，原來為<Directory "">;，改成：
<Directory "/var/www">;
//Indexes：當(dāng)在目錄中找不到DirectoryIndex列表中指定的文件就生成當(dāng)前目錄的文件列表
//FollowSymlinks：允許符號鏈接跟隨，訪問不在本目錄下的文件
Options Indexes FollowSymLinks
//禁止讀取.htaccess配置文件的內(nèi)容
AllowOverride None
//指定先執(zhí)行Allow（允許）訪問規(guī)則，再執(zhí)行Deny（拒絕）訪問規(guī)則
Order allow,deny
//設(shè)置Allow（允許）訪問規(guī)則，允許所有連接
Allow from all
</Directory>;

啟動服務(wù)：
# /usr/local/apache/bin/apachectl start
或
# service httpd start

Go to top.

3.安裝php 4.3.11
# wget http://cn2.php.net/get/php-4.3.11.tar.bz2/from/cn.php.net/mirror
# tar -jxvf php-4.3.11.tar.bz2
# cd php-4.3.11
# ./configure \
--prefix=/usr/local/php \
--with-mysql=/usr/local/mysql \
--with-apxs2=/usr/local/apache/bin/apxs
# make
# make install
# cp php.ini-dist /usr/local/php/lib/php.ini

# vi /usr/local/php/lib/php.ini
;default_charset = "iso-8859-1"
在這行下面加一行
default_charset = "gbk"

# vi /usr/local/apache/conf/httpd.conf
找到#AddType application/x-tar .tgz 這行，在下面加兩行。
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
找到下面一行在后面加上index.php，這表示網(wǎng)站的默認(rèn)頁也能夠為index.php
DirectoryIndex index.html index.html.var index.php
注意：改變了http.conf后，要重啟apache服務(wù)器，否則不會生效！

php常用配置
max_execution_time = 30 ; // 改為600 (增加處理腳本的時間限制)
max_input_time = 600 ; //最大輸出時間600秒
memory_limit = 8M ; //改為40M (這樣才能發(fā)10M的附件)
register_global =On
post_max_size = 2M ; //php可接受的 post 方法大小 2M
file_uploads = On ; //允許上載文件
upload_max_filesize = 2M ; //最大上載文件2M
session.auto_start = 1 ; //session自動啟動

Go to top.

4.安裝cyrus-sasl 2.1.20
如果系統(tǒng)安裝已經(jīng)，先卸載它，或使用下面方法關(guān)閉它
# mv /usr/lib/sasl /usr/lib/sasl.OFF
# mv /usr/lib/sasl2 /usr/lib/sasl2.OFF

編譯安裝cyrus-sasl2.1.20
# wget ftp://ftp.andrew.cmu.edu/pub/cyrus-mail/cyrus-sasl-2.1.20.tar.gz
# tar zxvf cyrus-sasl-2.1.20.tar.gz
# cd cyrus-sasl-2.1.20
# ./configure \
--disable-anon -enable-plain --enable-login \
--enable-sql --with-mysql=/usr/local/mysql \
--with-mysql-includes=/usr/local/mysql/include/mysql \
--with-mysql-libs=/usr/local/mysql/lib/mysql
# make
# make install

為了讓postfix能找到sasl，請運行如下命令：
# echo "/usr/local/lib" >;>; /etc/ld.so.conf
# ldconfig

# ln -s /usr/local/lib/sasl2 /usr/lib/sasl2

cyrus-sasl的密碼是不加密的，可以下載加密認(rèn)證補丁
# http://www.viperstrike.com/~lopaka/sysadmin/cyrus-sasl-mysql-encrypt/software-sources/patch-linux
# patch lib/checkpw.c patch-linux
重新編譯安裝
# LDFLAGS="-lcrypt" ./configure --disable-anon -enable-plain --enable-login --enable-sql --with-mysql=/usr/local/mysql --with-mysql-includes=/usr/local/mysql/include/mysql --with-mysql-libs=/usr/local/mysql/lib/mysql
# make
# make install

Go to top.

5.安裝postfix 2.2.3
如果你的系統(tǒng)上原來有sendmail，先將其停止并將其文件改名：
# /etc/init.d/sendmail stop
# chkconfig --level 0123456 sendmail off
# mv /usr/bin/newaliases /usr/bin/newaliases.orig
# mv /usr/bin/mailq /usr/bin/mailq.orig
# mv /usr/sbin/sendmail /usr/sbin/sendmail.orig

開始安裝
# groupadd -g 12345 postfix
# useradd -u 12345 -g 12345 -c postfix -d/dev/null -s/bin/false postfix
# groupadd -g 54321 postdrop
# wget ftp://postfix.cn99.com/postfix/official/postfix-2.2.3.tar.gz
# tar -zxvf postfix-2.2.3.tar.gz
# cd postfix-2.2.3
(Building Postfix with SASL authentication and mysql support)
# make -f Makefile.init makefiles \
'CCARGS=-DHAS_MYSQL -I/usr/local/mysql/include/mysql -DUSE_SASL_AUTH -I/usr/local/include/sasl' \
'AUXLIBS=-L/usr/local/mysql/lib/mysql -lmysqlclient -lz -lm -L/usr/local/lib -lsasl2'
# make install
如果/etc/aliases文件不存在，請用如下命令創(chuàng)建：
# echo postfix: root >;>; /etc/aliases
# /usr/bin/newaliases

注意：
本例中Mysql安裝在/usr/lcoal/mysql，sasl2安裝在/usr/lib/sasl2。如果安裝路徑不同，請自行修改編譯時CCARGS和AUXLIBS選項。
在執(zhí)行make install的時候可能會得到如下的提示(如果沒有就不用管了)：
/usr/libexec/ld-elf.so.1: Shared object "libmysqlclient.so.12" not found
這是因為mysql不是安裝在默認(rèn)目錄中的，所以需要告訴postfix應(yīng)該到哪里去找libmysqlclient.so.12，使用ldconfig就可以達(dá)到這個目的：
# echo /usr/local/mysql/lib/mysql >;>; /etc/ld.so.conf
# ldconfig

Go to top.

6.安裝postfixadmin 2.1.0
建立apache和maildrop的用戶和組
# groupadd vmail -g 1001
# useradd vmail -u 1001 -g 1001 -s/bin/false -d/dev/null

# vi /usr/local/apache/conf/httpd.conf
把
User nobody
Group #-1
改為
User vmail
Group vmail

# wget http://high5.net/postfixadmin/download.php?file=postfixadmin-2.1.0.tgz
# tar -zxvf postfixadmin-2.1.0.tgz
# mv postfixadmin-2.1.0 /var/www/postfixadmin
更改權(quán)限，假定運行apache的用戶和組為vmail
# chown -R vmail:vmail /var/www/postfixadmin
# cd /var/www/postfixadmin
# chmod 640 *.php *.css
# cd /var/www/postfixadmin/admin/
# chmod 640 *.php .ht*
# cd /var/www/postfixadmin/images/
# chmod 640 *.gif *.png
# cd /var/www/postfixadmin/languages/
# chmod 640 *.lang
# cd /var/www/postfixadmin/templates/
# chmod 640 *.tpl
# cd /var/www/postfixadmin/users/
# chmod 640 *.php

建立mysql表
# cd /var/www/postfixadmin
# mysql -u root [-p] < DATABASE_MYSQL.TXT
# cp config.inc.php.sample config.inc.php
# vi config.inc.php
本例中的配置如下：
// Language config
// Language files are located in './languages'.
$CONF['default_language'] = 'cn';
// Database Config
// 'database_type' is for future reference.
$CONF['database_type'] = 'mysql';
$CONF['database_host'] = 'localhost';
$CONF['database_user'] = 'postfixadmin';
$CONF['database_password'] = 'postfixadmin';
$CONF['database_name'] = 'postfix';
//$CONF['encrypt'] = 'md5crypt';
$CONF['encrypt'] = 'cleartext';
// Mailboxes
// If you want to store the mailboxes per domain set this to 'YES'.
// Example: /usr/local/virtual/domain.tld/username@domain.tld
$CONF['domain_path'] = 'YES';
// If you don't want to have the domain in your mailbox set this to 'NO'.
// Example: /usr/local/virtual/domain.tld/username
$CONF['domain_in_mailbox'] = 'NO';
// Quota
// When you want to enforce quota for your mailbox users set this to 'YES'.
$CONF['quota'] = 'YES';
// You can either use '1024000' or '1048576'
$CONF['quota_multiplier'] = '1024000';

我們在這里使用明文口令方式，如果想使用密文，請把$CONF['encrypt']='cleartext';改成$CONF['encrypt']='md5crypt';
郵箱的存儲格式使用domain.ltd/username的形式，所以設(shè)置：
$CONF['domain_path'] = 'YES';
$CONF['domain_in_mailbox'] = 'NO';

然后打開瀏覽器，進(jìn)入postfixadmin的歡迎界面，點擊網(wǎng)頁上的setup，看看檢查是否通過，記得要刪除setup.php文件。然后進(jìn)入http://www.yourdomain.com/postfixadmin/admin/index.php，就可以新建域名、管理員以及郵箱了。

7.安裝Courier-authlib 0.55
新版本的imap不再包含authentication library，必須先安裝 Courier authentication library
# wget http://www.courier-mta.org/beta/courier-authlib/courier-authlib-0.55.20050407.tar.bz2
# tar -jxvf courier-authlib-0.55.20050407.tar.bz2
# cd courier-authlib-0.55.20050407
# ./configure \
--with-redhat \
--with-authmysql=yes \
--with-mailuser=vmail --with-mailgroup=vmail \
--with-mysql-libs=/usr/local/mysql/lib/mysql --with-mysql-includes=/usr/local/mysql/include/mysql/
# make
# make install
# make install-configure

# vi /usr/local/etc/authlib/authdaemonrc （確保只使用mysql認(rèn)證模塊）
authmodulelist="authmysql"
authmodulelistorig="authmysql"

# vi /usr/local/etc/authlib/authmysqlrc
MYSQL_SERVER localhost
MYSQL_SOCKET /tmp/mysql.sock
MYSQL_DATABASE postfix
MYSQL_USERNAME postfix
MYSQL_PASSWORD postfix
MYSQL_USER_TABLE mailbox
MYSQL_LOGIN_FIELD username
#MYSQL_CRYPT_PWFIELD password
MYSQL_CLEAR_PWFIELD password
MYSQL_UID_FIELD '1001'
MYSQL_GID_FIELD '1001'
MYSQL_HOME_FIELD '/var/mailbox/'
MYSQL_MAILDIR_FIELD maildir
MYSQL_NAME_FIELD name
MYSQL_QUOTA_FIELD quota
MYSQL_WHERE_CLAUSE active='1'
DEFAULT_DOMAIN test.com
注意：確認(rèn)在這個文件中不能用空格鍵，只能用tab鍵。
確認(rèn)只使用單引號，比如：'/var/mailbox/','UID','GID'（本文為'1001'）
localhost不能用單引號
確認(rèn)你的/etc/hosts文件中有l(wèi)ocalhost
編譯時如果支持Ipv6可能導(dǎo)致錯誤
MYSQL_GID_FIELD 和MYSQL_UID_FIELD是maildrop的UID和GID，而不是MySQL的。
如果想使用md5密碼，把MYSQL_CLEAR_PWFIELD password改成MYSQL_CRYPT_PWFIELD password

啟動服務(wù)
要是想讓imap開機(jī)就啟動服務(wù)：
# cp courier-authlib.sysvinit /etc/rc.d/init.d/courier-authlib
# chmod 755 /etc/rc.d/init.d/courier-authlib
# chkconfig --level 0123456 courier-authlib on
手動啟動服務(wù)：
# authdaemond start

測試courier-authlib
檢查進(jìn)程：
# pstree |grep authdaemond

9.安裝Courier-maildrop 1.8.0
# groupadd vmail -g 1001
# useradd vmail -u 1001 -g 1001 -s/bin/false -d/dev/null
# wget http://jaist.dl.sourceforge.net/sourceforge/courier/maildrop-1.8.0.tar.bz2
# tar jxvf maildrop-1.8.0.tar.bz2
# cd maildrop-1.8.0
# ./configure \
--prefix=/usr/local/maildrop \
--enable-sendmail=/usr/sbin/sendmail \
--enable-trusted-users='root vmail' \
--enable-syslog=1 \
--enable-maildirquota \
--enable-maildrop-uid=1001 \
--enable-maildrop-gid=1001 \
--with-trashquota \
--with-dirsync
# make
# make install
# cp /usr/local/maildrop/bin/maildrop /usr/bin
# chmod a+rx /usr/bin/maildrop

運行maildrop -v應(yīng)該有如下提示信息：
maildrop 1.8.0 Copyright 1998-2004 Double Precision, Inc.

新建/etc/maildroprc文件
# vi /etc/maildroprc
logfile "/var/mailbox/maildrop.log"
to "$HOME$DEFAULT"

# chmod a+r /etc/maildroprc

配置Postfix
# vi /etc/postfix/main.cf
virtual_transport = maildrop
maildrop_destination_recipient_limit = 1

# vi /etc/postfix/master.cf
maildrop unix - n n - - pipe
flags=DRhu user=vmail:vmail argv=/usr/local/maildrop/bin/maildrop -w 90 -d ${recipient}

由于maildrop沒有建立maildir的功能，因此由一小斷腳本實現(xiàn)
# vi /etc/sudoers
vmail ALL = NOPASSWD: /usr/sbin/maildirmake.sh

新建/usr/sbin/maildirmake.sh文件
# vi /usr/sbin/maildirmake.sh
#!/bin/bash
set -e
if [ ! -f /var/mailbox/$1 ]
then
mkdir /var/mailbox/$1
fi
chown -R vmail:vmail /var/mailbox/$1
cd "/var/mailbox/$1"
/usr/local/imap/bin/maildirmake $2
chown -R 1001:12345 /var/mailbox/$1/$2
chmod -R g=s /var/mailbox/$1/$2

# chmod 755 /usr/sbin/maildirmake.sh

更改postfixadmin/admin目錄下的create-mailbox.php文件
在此文件的200行后加一行：
# vi /var/www/postfixadmin/admin/create-mailbox.php
system("sudo /usr/sbin/maildirmake.sh $fDomain ".$_POST['fUsername']);

說明：
建立的郵箱格式：/var/vmail/domain.tld/username
uid 1001 是vmail的用戶id，也是目錄/var/vmail的owner
gid 12345 是postfix的組id

在postfixadmin中建立一測試帳戶test@test.com
測試maildrop
# maildrop -V 9 -d test@test.com
maildrop: authlib: groupid=1001
maildrop: authlib: userid=1001
maildrop: authlib: logname=test@test.com, home=/var/mailbox/, mail=test.com/test/
maildrop: Changing to /var/mailbox/
ctrl+c退出

下一步，查看日志(/var/log/maillog)看看postfix是不是和maildrop一起工作：
# cat /var/log/maillog | grep maildrop -A 2
Feb 28 11:50:41 malochia postfix/qmgr[7345]: 2875B7823E62: from=<remote@user.nl>;, size=3308, nrcpt=1 (queue active)
Feb 28 17:18:05 malochia postfix/pipe[11615]: 04DD57822697: to=<user@domain.tld>;, relay=maildrop, delay=0, status=sent (domain.tld)

如果沒有，看看是不是由于配置不正確，而使郵件在隊列中
# Mailq

配置quotas
新建文件/usr/local/maildrop/etc/quotawarnmsg
# vi /usr/local/maildrop/etc/quotawarnmsg
From: 管理員 test.com <postmaster@test.com>;
Reply-To: postmaster@test.com
To: Valued Customer:;
Subject: 警告！您的郵箱空間即將用完！
Mime-Version: 1.0
Content-Type: text/plain; charset=gb2312
Content-Transfer-Encoding: 8bit

親愛的用戶，您的郵箱空間已用了90％。如果還想繼續(xù)收到郵件的話，請刪除一些郵件。

設(shè)置quotas
Postfixadmin的數(shù)據(jù)庫的maildrop表的quota字段是int類型的，在maildrop下不能工作，不過我們可以修改 /usr/local/etc/authlib/authmysqlrc文件，把其中的MYSQL_QUOTA_FIELD quota一行改為MYSQL_QUOTA_FIELD concat(quota,'S') ，如果你想限制郵件的數(shù)量，也可以改成MYSQL_QUOTA_FIELD concat(quota,'C')。
如果我們把一個用戶的郵箱設(shè)為10M，我們可以把quota的值改為“10000000S”。也可以用“C”，“1000C”的意思是只能存放1000條郵件。

給test@test.com發(fā)一封信，但是不用包含附件。然后：
# cd /var/mailbox/test.com/test
# cat maildirsize
1000000S
1622 1

maildirsize這個文件存儲了郵箱配額的信息，而且courier-imap也用這個文件。
舉個例子說明一下該文件，我的一個maildirsize文件的內(nèi)容如下：
# cat maildirsize
5000000S
42898 9
3403 1
1622 1
2371 1

說明這個郵箱的容量是5M（如果你把quota字段的值刪除，maildrop會自動給它一個值，但是不要把它的值設(shè)置成null），現(xiàn)在郵箱里有四封信。
假設(shè)該用戶用掉了5M中的3M，只剩2M了，如果來了一封大于2M的郵件，將會被退回，如果是1.7M的郵件，maildrop會收下該郵件，更新maildirsize文件，重新計算quota，得知該用戶使用了90％（/etc/postfix/master.cf中的-w 90）以上的配額，maildrop會拷貝/usr/local/maildrop/etc/quotawarnmsg文件到該用戶的郵箱中警告該用戶。

10.webmail

10.1.安裝sqwebmail 5.0.1
# wget http://optusnet.dl.sourceforge.net/sourceforge/courier/sqwebmail-5.0.1.tar.bz2
# tar jxvf sqwebmail-5.0.1.tar.bz2
# cd sqwebmail-5.0.1
# ./configure \
--prefix=/usr/local/sqwebmail \
--enable-unicode=utf-8,iso-8859-1,gb2312,gbk,gb18030 \
--with-trashquota
# make configure-check
# make
# make install-strip
# make install-configure

啟動服務(wù)
# /usr/local/sqwebmail/libexec/sqwebmaild.rc start

測試sqwebmail
http://192.168.0.5/cgi-bin/sqwebmail
使用用戶test@test.com,密碼test，登陸進(jìn)出以后就可以測試收發(fā)郵件了。但是圖片不能顯示，只要
# mv /usr/local/apache/htdocs/webmail /var/www

修改Apache
# cd /var/www
# vi index.html //輸入一下內(nèi)容：
<html>;
<head>;
<title>;MAIL SYSTEM</title>;
<meta http-equiv="Content-Type" content="test/html;charset=gb2312">;
<meta http-equiv="refresh" content="0;url=http://mail.test.com/cgi-bin/sqwebmail">;
</head>;
<body bgcolor="#FFFFFF" test="#000000">;
</html>;

經(jīng)過以上修改以后，你就可以通過：http://mail.test.com 直接來訪問sqwebmail了，這樣就方便多了。可惜是英文的，不知道哪位達(dá)人能漢化一下，并把界面改的漂亮一點就好了。

10.2.安裝squirrelmail 1.4.4
下載squirrelmail及中文包
# wget http://jaist.dl.sourceforge.net/sourceforge/squirrelmail/squirrelmail-1.4.4.tar.bz2
# wget http://jaist.dl.sourceforge.net/sourceforge/squirrelmail/zh_CN-1.4.4-20050122.tar.bz2
把squirreelmail解壓到/var/www目錄下。
# tar -jxvf squirrelmail-1.4.4.tar.bz2 -C /var/www/
# mv /var/www/squirrelmail-1.4.4 /var/www/squirrelmail
解壓中文包
# tar -jxvf zh_CN-1.4.4-20050122.tar.bz2 -C /var/www/squirrelmail/

在配置squirrelmail之前先下載三個插件：
Quota Usage Version 1.3
# wget http://www.squirrelmail.org/countdl.php?fileurl=http%3A%2F%2Fwww.squirrelmail.org%2Fplugins%2Fquota_usage-1.3-1.2.7.tar.gz
Compatibility Version 1.3
# wget http://www.squirrelmail.org/countdl.php?fileurl=http%3A%2F%2Fwww.squirrelmail.org%2Fplugins%2Fcompatibility-1.3.tar.gz
Change MySQL Password Version 3.2
# wget http://www.squirrelmail.org/countdl.php?fileurl=http%3A%2F%2Fwww.squirrelmail.org%2Fplugins%2Fchange_mysqlpass-3.2-1.2.8.tar.gz

把這三個插件解壓到squirrelmail的plugin目錄下并設(shè)置權(quán)限。
# tar -zxvf quota_usage-1.3-1.2.7.tar.gz -C /var/www/squirrelmail/plugins/
# tar -zxvf compatibility-1.3.tar.gz -C /var/www/squirrelmail/plugins/
# tar -zxvf change_mysqlpass-3.2-1.2.8.tar.gz -C /var/www/squirrelmail/plugins/
第一個插件是用來顯示郵箱的使用情況的；第二個和第三個插件是用來修改密碼的。
如果不想裝這些插件，請?zhí)^。

配置Quota Usage
# cd /var/www/squirrelmail/plugins/quota_usage
# cp config.php.sample config.php

配置Change MySQL Password
# cd /var/www/squirrelmail/plugins/change_mysqlpass
# cp config.php.sample config.php
# vi config.php
更改如下幾個變量：
$mysql_database = 'postfix';
$mysql_table = 'mailbox';
$mysql_userid_field = 'username';
$mysql_password_field ='password';
$mysql_manager_id = 'postfix';
$mysql_manager_pw = 'postfix';
$mysql_unixcrypt = 0;
//$mysql_MD5crypt = 1;
$mysql_MD5crypt = 0;
$use_ssl_for_password_change = 0;

如果你的密碼是MD5加密的，就把$mysql_MD5crypt = 0;改成$mysql_MD5crypt = 1;

配置squirrelmail
# cd /var/www/squirrelmail
# ./configure
進(jìn)入10. Languages
把1. Default Language : 的en_US改成zh_CN。
進(jìn)入8. Plugins，添加這三個插件

打開瀏覽器輸入http://192.168.0.5/squirrelmail/，用test@test.com登陸，你將會在屏幕的左上角看到郵箱的使用情況，你還會看到一條警告信息：
Warning: mysql_result(): supplied argument is not a valid MySQL result resource in /var/www/squirrelmail/plugins/change_mysqlpass/functions.php on line 129
這是由于數(shù)據(jù)庫結(jié)構(gòu)不一致造成的，你只要把functions.php中的129行注釋調(diào)即可（在行首加//）。
現(xiàn)在你還可以用選項中的change passwd修改你的密碼了，不過這個模塊是英文的，如果你想改成中文的，可以自己修改，squirrelmail網(wǎng)站上有介紹�；蛘哒垍⒖迹�
http://datastrategy.org/number5/archives/000241.html
1、把change_mysqlpass.po與locale/zh_CN/LC_MESSAGES/squirrelmail.po合并
最簡單的方法就是:
# cat change_mysqlpass.po >;>; /var/www/squirrelmail/locale/zh_CN/LC_MESSAGES/squirrelmail.po
2、執(zhí)行：
# cd /var/www/squirrelmail/locale/zh_CN/LC_MESSAGES/
# msgfmt -o squirrelmail.mo squirrelmail.po

由于安全原因，建議把data目錄移出web tree，比如移到/usr目錄下，設(shè)置權(quán)限
# cp -R /var/www/squirrelmail/data/ /var/data
# chown -R vmail.vmail /var/data
# chmod 730 -R /var/data

安裝suidperl（9.0安裝盤的第二張盤中有）
# wget http://turtle.ee.ncku.edu.tw/openwebmail/download/redhat/rpm/packages/rh9/perl-suidperl-5.8.0-88.i386.rpm
# rpm -ivh perl-suidperl-5.8.0-88.i386.rpm

如果采用 rpm 安裝，安裝系統(tǒng)會自動對應(yīng)到正確路徑。若使用手動安裝，將openwebmail目錄及data目錄移至如下/var/www/cgi-bin/openwebmail及/var/www/data，我是用tarball安裝的
# wget http://openwebmail.org/openwebmail/download/release/openwebmail-2.51.tar.gz
# tar zxvf openwebmail-2.51.tar.gz -C /var/www

加入openwebmail的權(quán)限，編輯httpd.con，加入如下內(nèi)容，假設(shè)/var/www/cgi-bin是apache的cgi-bin目錄
# vi /usr/local/apache/conf/httpd.conf
ScriptAlias /openwebmail "/var/www/cgi-bin/openwebmail/openwebmail.pl"

存盤后重新啟動apache
# service httpd restart

編輯mysql認(rèn)證文件
# vi /var/www/cgi-bin/openwebmail/auth/auth_mysql.pl
my $SQLHost = 'localhost';
my $sqlusr = 'postfix';
my $sqlpwd = 'postfix';
my $auth_db = 'postfix';
my $auth_table = 'mailbox';
my $field_username = 'username';
my $field_password = 'password';
my $field_realname = 'name';
my $field_uid = '1001';
my $field_gid = '1001';
my $field_home = 'maildir';
my $pass_type = 'cleartxt';

編輯openwebmail主配置文件
# vi /var/www/cgi-bin/openwebmail/etc/openwebmail.conf
domainnames auto
auth_module auth_mysql.pl
auth_withdomain yes
mailspooldir /var/mailbox
create_syshomedir new
use_syshomedir new
ow_cgidir /var/www/cgi-bin/openwebmail

quota_limit 30000 #用戶主目錄磁盤上限30M
spool_limit 10000 #收件箱上限10M /var/mail

enable_webdisk no
enable_sshterm no

接下來執(zhí)行初始化
# /var/www/cgi-bin/openwebmail/openwebmail-tool.pl --init

將dbm.conf中的設(shè)定改為執(zhí)行初始化后系統(tǒng)所要求的
# cp /var/www/cgi-bin/openwebmail/etc/defaults/dbm.conf /var/www/cgi-bin/openwebmail/etc/
# vi /var/www/cgi-bin/openwebmail/etc/dbm.conf
dbm_ext .db
dbmopen_ext .db
dbmopen_haslock no

再執(zhí)行一次初始化
# /var/www/cgi-bin/openwebmail/openwebmail-tool.pl --init

這時便會出現(xiàn)一些訊息，最后出現(xiàn)一行
Send the site report?(Y/n)
按 Enter 即可，這樣便完成 openwebmail 的設(shè)定

創(chuàng)建日志文件并設(shè)置logrotate
# touch /var/log/openwebmail.log
# vi /etc/logrotate.d/syslog （加入下面幾行）
/var/log/openwebmail.log {
postrotate
/usr/bin/killall -HUP syslogd
endscript
}

測試
http://192.168.1.5/openwebmail

openwebmail不支持Maildir，所以照這篇文章的設(shè)置，將不能收郵件，可以打個補�。ǚ枪俜教峁部梢园裵ostfix改成Mailbox格式的，但是我更期待支持Maildir的官方版，應(yīng)該快了吧！

新建文件/var/amavisd/.spamassassin/user_prefs
# touch /var/amavis/.spamassassin/user_prefs

檢查local.cf語法
# spamassassin --lint

bayes（計劃中）

啟動spamd
# /usr/bin/spamd --daemonize --pidfile /var/run/spamd.pid

下載中文垃圾垃圾郵件過濾規(guī)則Chinese_rules.cf
# wget -N -P /usr/share/spamassassin www.ccert.edu.cn/spam/sa/Chinese_rules.cf

每次更新Chinese_rules.cf需要重啟spamd方法如下
# kill -HUP `cat /var/run/spamd.pid`

自動更新中文垃圾垃圾郵件過濾規(guī)則
# vi /etc/crontab (加一行)
0 0 1 * * root wget -N -P /usr/share/spamassassin www.ccert.edu.cn/spam/sa/Chinese_rules.cf;kill -HUP `cat /var/run/spamd.pid`

測試病毒掃描
使用其他郵件系統(tǒng)用戶給該系統(tǒng)的用戶發(fā)送郵件,包含以下內(nèi)容:
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
如果這個用戶能夠收到有病度提示的郵件說明病毒過濾已經(jīng)成功!
郵件病毒掃描日志將被記錄在/var/log/clamav/clamav.log中!

測試?yán)]件掃描
使用其他郵件系統(tǒng)用戶給該系統(tǒng)的用戶發(fā)送郵件,包含以下內(nèi)容:
XJS*C4JDBQADN1.NSBN3*2IDNEN*GTUBE-STANDARD-ANTI-UBE-TEST-EMAIL*C.34X
然后查看郵件日志看看，發(fā)出的郵件是否被BOUNCE或DISCARD了

建立maildrop過濾腳本(如果你使用amavisd-new來對spamassassin進(jìn)行操作的話,跳過該項)
# vi /etc/maildroprc
if ( $SIZE < 26144 )
{
exception {
xfilter "/usr/bin/spamassassin"
}
}

if (/^X-Spam-Flag: *YES/)
{
exception {
to "$HOME$DEFAULT/.Spam/"
}
}
else
{
exception {
to "$HOME$DEFAULT"
}
}

14.后記
大功告成，終于結(jié)束了。這篇文章花了本人無數(shù)心血，參考了無數(shù)篇文章，多少個日日夜夜啊，好幾次煩得差點吐血，但是我堅持下來了。希望各位能夠成功。
