9. squirrelmail (Mail web) provides the web mail interface to automatically install Apache

Using aptitude install or apt-Get install In Debian is easier than windows, so you can find it online.

The following describes how to create a MySQL database:

Create databases and tables
Mysqladmin password 2006 Root Password: 2006
Mysqladmin-P Create mail creates a mail database

Mysql>
Grant select on mail .*
To mailuser @ localhost
Identified by '20140901 ';
Exit
The password for creating a mailuser is: 2007, which only has the permission to query mail data inventory.

Create a virtual domain table: Domains
Mysql>
Create Table 'domains '(
Id int not null auto_increment primary key,
Name varchar (50) not null
) Engine = InnoDB;

Create a virtual user table: 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;

Create a view_users table to facilitate query and further setup and verification.
Mysql>
Create view view_users
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;

Create a virtual alias table: 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
Select Concat (aliases. Source, '@', domains. Name) as email,
Destination
From aliases
Left join domains on aliases. domain_id = domains. ID;

Create a virtual domain ing file:
/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'

Create a virtual mailbox ing File
/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'

Create a virtual alias ing File
/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 vemail-u 5000 vmail-D/home/vmail-m
$> Postconf-e virtual_uid_maps = static: 5000
$> Postconf-e virtual_gid_maps = static: 5000
To ensure the security of *. Cf files, the built-in password is used;
Chgrp Postfix/etc/Postfix/virtual-*. cf
Chmod u = RW, G = r, O =/etc/Postfix/virtual-*. cf

Configure Dovecot
To enable Postfix to send mail with Dovecot, add the following services under/etc/Postfix/master. Cf:
Dovecot Unix-N-pipe
Flags = drhu user = vmail: vmail argv =/usr/lib/Dovecot/deliver-d $ {recipient}
To enable Postfix to use Dovecot for virtual transmission, add the following items to main. Cf:
$> Postconf-e virtual_transport = Dovecot
$> Postconf-e dovecot_destination_recipient_limit = 1

Configure Dovecot. conf
/Etc/Dovecot. conf

Add the following service support
Protocols = IMAP IMAPs POP3 pop3s

Plaintext password authentication is not removed
Disable_plaintext_auth = No

Tell Dovecot that the email is placed in/home/vmail/domain/user in the form of maildir
Mail_location = maildir:/home/vmail/% d/% N

Set authentication mechanism
Machisms = plain Login

Tell Dovecot that the password is in the SQL database
Passdb SQL {
ARGs =/etc/Dovecot/dovecot-sql.conf
}

Similar to mail_location, when a user obtains an email, it is recorded as a log.
Userdb static {
ARGs = uid = 5000 gid = 5000 home =/home/vmail/% d/% N allow_all_users = Yes
}

The master part stores new emails in the user's mailbox through the user's data inventory information.
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
}< BR >}< br> You must customize this part: dovecot Lda is much more powerful than the built-in LDA function of Postfix. It can set quotas and email filtering,
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

Configure 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 ';

Change the permission of Dovecot. conf. Set only the user in the vmail group and the root user name to read
$> Chgrp vmail/etc/Dovecot. conf
$> Chmod g + R/etc/Dovecot. conf

Configure SMTP authentication (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

9. Configure WebMail

Ln-S/usr/share/squirrelmail/var/www/mail
Check whether Web server: apache2 has been started:
Netstat-an | grep: 80
TCP 0 0 0.0.0.0: 80 0.0.0.0: * listen

In this case, you can use http: // ip/mail to access webmail.
If you want your webmail interface to be simplified Chinese, enter your email address and password, and choose Options> display preferences> language:> Chinese Simple.
If you want to set the webmail interface to simplified Chinese by default, run/etc/squirrelmail/CONF. pl and enter 10. You can see the following interface:
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

Set to similar:
Squirrelmail configuration: Read: config. php (1.4.0)
---------------------------------------------------------
Language preferences
1. default language: zh_cn
2. Default charset: gb2312
3. Enable lossy encoding: false

Restart the Web Service:
/Etc/init. d/apache2 restart
Forcing reload of Web Server: apache2.

Use http: // ip/mail to access web mail. You can find that the default language of squirrelmail has changed to simplified Chinese.

Note: squirrelmail supports many extension functions such as password modification, automatic reply, and incoming call reminder. Download the corresponding plug-in installation package from the squirrelmail website. Http://www.squirrelmail.org
