9.squirrelmail(MAIL WEB)提供web mail接口,自动装上apache

debian 中安装软件用aptitude install 或apt-get install 比windows 还简单，在这里就不占篇幅了，不会的可以上网找一下。

下面是MYSQL数据库的创建:

创建数据库及表

mysqladmin password 2006 root的密码为:2006

mysqladmin -p create mail创建一个为mail的数据库

mysql>

GRANT Select ON mail.*

TO mailuser@localhost

IDENTIFIED BY '2007';

exit

创建一个mailuser的用户密码为:2007只有对mail数据库存查询权限

创建虚拟虚拟域表:domains

mysql>

Create TABLE `domains` (

id INT NOT NULL AUTO_INCREMENT PRIMARY KEY,

name VARCHAR(50) NOT NULL

) ENGINE = InnoDB;

创建虚拟用户表:users

Create TABLE users (

id int(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,

domain_id INT(11) NOT NULL,

user VARCHAR(40) NOT NULL,

password VARCHAR(32) NOT NULL,

CONSTRAINT UNIQUE_EMAIL UNIQUE (domain_id,user),

FOREIGN KEY (domain_id) REFERENCES domains(id) ON Delete CASCADE

) ENGINE = InnoDB;

创建 view_users表 方便查询及以后设置验证.

mysql>

Create VIEW view_users AS

Select users.user AS user, CONCAT(users.user, '@', domains.name) AS email,

users.password

FROM users

LEFT JOIN domains ON users.domain_id=domains.id;

创建虚拟别名表:aliases

Create TABLE aliases(

id int(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,

domain_id INT(11) NOT NULL,

source VARCHAR(20) NOT NULL,

destination VARCHAR(80) NOT NULL,

FOREIGN KEY (domain_id) REFERENCES domains(id) ON Delete CASCADE

) ENGINE = InnoDB;

Create VIEW view_aliases AS

Select CONCAT(aliases.source, '@', domains.name) AS email,

destination

FROM aliases

LEFT JOIN domains ON aliases.domain_id=domains.id;

创建虚拟域映射文件:

/etc/postfix/virtual-mailbox-domains.cf

user = mailuser

password = 2007

hosts = 127.0.0.1

dbname = mail

query = Select 1 FROM domains Where name='%s'

创建虚拟邮箱映射文件

/etc/postfix/virtual-mailbox-maps.cf

user = mailuser

password = 2007

hosts = 127.0.0.1

dbname = mail

query = Select 1 FROM view_users Where email='%s'

创建虚拟别名映射文件

/etc/postfix/virtual-alias-maps.cf

user = mailuser

password = 2007

hosts = 127.0.0.1

dbname = mail

query = Select destination FROM view_aliases Where email='%s'

/etc/postfix/virtual-email2email.cf

user = mailuser

password = 2007

hosts = 127.0.0.1

dbname = mail

query = Select email FROM view_users Where email='%s'

$>postconf -e virtual_mailbox_domains=mysql:/etc/postfix/virtual-mailbox-domains.cf

$>postconf -e virtual_mailbox_maps=mysql:/etc/postfix/virtual-mailbox-maps.cf

$>postconf -e virtual_alias_maps=mysql:/etc/postfix/virtual-alias-maps.cf,mysql:/etc/postfix/virtual-email2email.cf

$> groupadd -g 5000 vmail

$> useradd -g vmail -u 5000 vmail -d /home/vmail -m

$> postconf -e virtual_uid_maps=static:5000

$> postconf -e virtual_gid_maps=static:5000

为了保障*.cf文件的安全,因内置密码;

chgrp postfix /etc/postfix/virtual-*.cf

chmod u=rw,g=r,o= /etc/postfix/virtual-*.cf

配置dovecot

为了让postfix用dovecot传送邮件在/etc/postfix/master.cf下添加以下服务:

dovecot unix - n n - - pipe

flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient}

为了让postfix用dovecot作虚拟传输在main.cf中添加以下项

$> postconf -e virtual_transport=dovecot

$> postconf -e dovecot_destination_recipient_limit=1

配置dovecot.conf

/etc/dovecot/dovecot.conf

添加以下服务支持

protocols = imap imaps pop3 pop3s

不去除明文密码认证

disable_plaintext_auth = no

告诉dovecot邮件是以maildir形式放在/home/vmail/域/用户

mail_location = maildir:/home/vmail/%d/%n

设定认证机制

mechanisms = plain login

告诉dovecot密码在sql数据库中

passdb sql {

args = /etc/dovecot/dovecot-sql.conf

}

和mail_location相似,当用户取邮件时会以日志的形式记录下来

userdb static {

args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes

}

master部分将通过用户的数据库存信息把新的邮件保存在用户的邮箱中

socket listen {

master {

path = /var/run/dovecot/auth-master

mode = 0600

user = vmail

}

client {

path = /var/spool/postfix/private/auth

mode = 0660

user = postfix

group = postfix

}

}

这部份需要自已定制:dovecot的LDA比postfix自带的LDA功能强大的多,它可设定配额,和邮件过滤,

protocol lda {

log_path = /home/vmail/dovecot-deliver.log

auth_socket_path = /var/run/dovecot/auth-master

postmaster_address = wxy1@wxy.com

mail_plugins = cmusieve

global_script_path = /home/vmail/globalsieverc

配置dovecot-sql.conf

/etc/dovecot/dovecot-sql.conf

driver = mysql

connect = host=127.0.0.1 dbname=mail user=mailuser password=2007

default_pass_scheme = PLAIN

password_query = Select email as user, password FROM view_users Where user='%u';

改变dovecot.conf的权限,设只vmail 组的用户及root用名可以读取

$> chgrp vmail /etc/dovecot/dovecot.conf

$> chmod g+r /etc/dovecot/dovecot.conf

配置smtp验证(sasl)

$> postconf -e smtpd_sasl_type=dovecot

$> postconf -e smtpd_sasl_path=private/auth

$> postconf -e smtpd_sasl_auth_enable=yes

$> postconf -e smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination

九、配置webmail

ln -s /usr/share/squirrelmail /var/www/mail

查看 web server: Apache2 是否已启动：

netstat -an |grep :80

tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN

这时可以应该可以用http://IP/mail 访问webmail

如果你想个人的webmail界面是简体中文，请在输入邮箱及密码登录邮箱后，Options->Display Preferences->Language:->Chinese Simple。

如果想将webmail的界面默认为简体中文，请执行/etc/squirrelmail/conf.pl，输入10，可以看到如下界面：

SquirrelMail Configuration : Read: config.php (1.4.0)

---------------------------------------------------------

Language preferences

1. Default Language : en_US

2. Default Charset : iso-8859-1

3. Enable lossy encoding : false

设置成类似：

SquirrelMail Configuration : Read: config.php (1.4.0)

---------------------------------------------------------

Language preferences

1. Default Language : zh_CN

2. Default Charset : GB2312

3. Enable lossy encoding : false

重启web服务：

/etc/init.d/apache2 restart

Forcing reload of web server: Apache2.

再用http://IP/mail访问web mail，可以发现squirrelmail的默认语言已经变成了简体中文了。

注：squirrelmail支持用户修改密码、自动回复、来电提醒等相当多的扩展功能请至squirrelmail网站下载相应的插件安装包就可以了。http://www.squirrelmail.org

有不对之处请多指教！
