Mail Server (Postfix + Dovecot + Extmail + Extman Based on Virtual account)

Lab Topology

LAMP (Linux + Apache + MySQL + PHP) Environment Construction

First, we need to build a LAMP Environment

/Usr/local/mysql/lib

[Root @ mail mysql] # ldconfig

Process header files

[Root @ mail mysql] # ln-s include/usr/include/mysql

Add a password to the mysql database

Install php

[Root @ mail php-5.4.13] # tar-jxvf php-5.4.13.tar.bz2-C/usr/local/src/

[Root @ mail php-5.4.13] #. /configure -- prefix =/usr/local/php -- with-apxs2 =/usr/local/apache/bin/apxs -- with-mysql =/usr/local/mysql -- with-mysqli = /usr/local/mysql/bin/mysql_config -- enable-mbstring -- enable-xml -- with-png-dir -- with-png -- with-jpeg-dir -- with-zlib -- enable -mbstring -- with-freetype-dir

Support php module for editing apache configuration files

Set up exymail below

This is mainly used to build extmail in Beijing.

Disable the sendmail function of the Development Platform because you need to set up extmail.

Change host name and dns point

Disable sendmail and set it to disabled at startup

Upload the required software package to build extmail

Postfix-2.8.2.tar.gz

Courier-authlib-0.63.0.tar.bz2

Unix-Syslog-0.100.tar.gz

Extmail-1.2.tar.gz

Extman-1.1.tar.gz

Set saslauth service to start

Install other software packages

Yum install mysql-devel

Install postfix

[Root @ host ~] # Tar-zxvf postfix-2.8.2.tar.gz-C/usr/local/src/

[Root @ host ~] # Cd/usr/local/src/postfix-2.8.2/

[Root @ host postfix-2.8.2] # group-g 2525 postfix

-Bash: group: command not found

[Root @ host postfix-2.8.2] # groupadd-g 2525 postfix

[Root @ host postfix-2.8.2] # useradd-g postfix-u 2525-s/sbin/nologin-M postfix

[Root @ host postfix-2.8.2] # groupadd-g 2526 postdrop

[Root @ host postfix-2.8.2] # useradd-g postdrop-u 2526-s/bin/false-M postdro

The Mysql path must be correct.

[Root @ host postfix-2.8.2] # make & make install

Install_root: [/]/

Tempdir: [/usr/local/src/postfix-2.6.5]/tmp

Config_directory: [/etc/postfix]

Daemon_directory: [/usr/libexec/postfix]

Command_directory: [/usr/sbin]

Queue_directory: [/var/spool/postfix]

Sendmail_path: [/usr/sbin/sendmail]

Newaliases_path: [/usr/bin/newaliases]

Mailq_path: [/usr/bin/mailq]

Mail_owner: [postfix]

Setgid_group: [postdrop]

Html_directory: [no]/var/www/postfix_html

Manpages: [/usr/local/man]

Readme_directory: [no]

Run/usr/bin/newaliases to generate a new alias file, which improves the postfix efficiency.

[Root @ host postfix-2.8.2] #/usr/bin/newaliases

2. Perform some basic configurations, test and start postfix, and send emails.

# Vi/etc/postfix/main. cf

To manage the shutdown of the postfix service, create a script and copy the control script of the postfix rpm package.

[Root @ host ~] # Cd/tmp/

[Root @ host tmp] # mkdir abc

[Root @ host tmp] # cd abc/

[Root @ host abc] # cp/mnt/cdrom/Server/postfix-2.3.3-2.1.el5_2.i386.rpm ./

[Root @ host abc] # rpm2cpio postfix-2.3.3-2.1.el5_2.i386.rpm | cpio-id

Edit the postfix configuration file

[Root @ host init. d] # vim/etc/postfix/main. cf

Configure email server relay

Test email sending

Enable the rycus-sasl-based authentication function for postfix.

Vim/etc/postfix/main. cf

Add authentication function

4. Install Courier authentication library

[Root @ host ~] # Tar jxvf courier-authlib-0.63.0.tar.bz2-C/usr/local/src/

[Root @ host ~] # Cd/usr/local/src/courier-authlib-0.63.0/

[Root @ mail courier-authlib-0.63.0] #./configure \

> -- Prefix =/usr/local/courier-authlib \

> -- Sysconfdir =/etc \

> -- With-authmysql \

> -- With-mysql-libs =/usr/local/mysql/lib \

> -- With-mysql-nodes des =/usr/local/mysql/include \

> -- With-redhat \

> -- With-authmysqlrc =/etc/authmysqlrc \

> -- With-authdaemonrc =/etc/authdaemonrc \

> -- With-ltdl-lib =/usr/lib \

> -- With-ltdl-include =/usr/include

[Root @ mail courier-authlib-0.63.0] # make

[Root @ mail courier-authlib-0.63.0] # make install

[Root @ mail courier-authlib-0.63.0] # chmod 755/usr/local/courier-authlib/var/spool/authdaemon

[Root @ mail courier-authlib-0.63.0] # cp/etc/authdaemonrc. dist/etc/authdaemonrc

[Root @ mail courier-authlib-0.63.0] # cp/etc/authmysqlrc. dist/etc/authmysqlrc

[Root @ mail etc] # vim/etc/authdaemonrc

[Root @ mail etc] # vim/etc/authmysqlrc

[Root @ mail etc] # cd/usr/local/src/courier-authlib-0.63.0/

[Root @ mail courier-authlib-0.63.0] # cp courier-authlib.sysvinit/etc/init. d

# Cp courier-authlib.sysvinit/etc/init. d/courier-authlib

# Chmod 755/etc/init. d/courier-authlib

# Chkconfig -- add courier-authlib

# Chkconfig -- level 2345 courier-authlib on

# Echo "/usr/local/courier-authlib/lib/courier-authlib">/etc/ld. so. conf. d/courier-authlib.conf

# Ldconfig-v

Start the service

[Root @ mail etc] # service courier-authlib start

Starting Courier authentication services: authdaemond

Create the directory where the virtual user mailbox is located, and grant its permission to the postfix User:

# Mkdir-pv/var/mailbox

# Chown-R postfix/var/mailbox

Next, reconfigure SMTP authentication and edit/usr/local/lib/sasl2/smtpd. conf to make sure it is the following content:

Pwcheck_method: authdaemond

Log_level: 3

Mech_list: PLAIN LOGIN

Authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket

5. Enable postfix to support virtual domains and virtual users

1. edit/etc/postfix/main. cf and add the following content:

2. Use extmail. SQL and init. SQL In the docs directory under the extman source code directory to create a database:

[Root @ mail ~] # Tar-zxvf extman-1.1.tar.gz

[Root @ mail ~] # Music extman-1.1/var/www/extsuite/extman

Because of the mysql version. Before importing the database, we need to perform extmail. SQL modification, extmail. delete the text line in the SQL statement, delete the line TYPE = MyISAMCOMMENT = 'extmail-Virtual mailboxes', and change line 87 to can_signup varchar (255 ).

[Root @ mail docs] # mysql-u root-p <extmail. SQL

Import and initialize the init. SQL script to the mysql database

[Root @ mail docs] # mysql-u root-p <init. SQL

View database verification after import

6. Configure dovecot

Already installed

Configure dovecot

[Root @ mail Server] # vim/etc/dovecot. conf

Configuration file used to create a connection between dovcot and mysql

[Root @ mail Server] # vim/etc/dovecot-mysql.conf

Set to boot

[Root @ mail Server] # chkconfig dovecot on

7. Install the Extmail-1.2 (first install httpd)

[Root @ mail ~] # Mkdir-pv/var/www/extsuite

[Root @ mail ~] # Tar-zxvf extmail-1.2.tar.gz

[Root @ mail ~] # Music extmail-1.2/var/www/extsuite/extmail

Cp/var/www/extsuite/extmail/webmail. cf. default/var/www/extsuite/extmail/webmail. cf

Edit configuration file

Apache configuration

Modifying the cgi execution file is a postfix user.

[Root @ mail extmail] # chown-R postfix. postfix/var/www/extsuite/extmail/cgi/

4. Dependency Solution

[Root @ mail ~] # Tar-zxvf Unix-Syslog-0.100.tar.gz-C/usr/local/src/

[Root @ mail ~] # Cd/usr/local/src/Unix-Syslog-0.100/

[Root @ mail Unix-Syslog-0.100] # perl Makefile. PL

[Root @ mail Unix-Syslog-0.100] # make

[Root @ mail Unix-Syslog-0.100] # make install

Restart the httpd server

8. Configure Extman-1.1

[Root @ mail ~] # Music extman-1.1/var/www/extsuite/extman

[Root @ mail ~] # Cp/var/www/extsuite/extman/webman. cf. default/var/www/extsuite/extman/webman. cf

[Root @ mail ~] # Vim/var/www/extsuite/extman/webman. cf

12 SYS_MAILDIR_BASE =/var/mailbox

21 SYS_CAPTCHA_ON = 0

127 SYS_MYSQL_USER = webman

128 SYS_MYSQL_PASS = webman

129 SYS_MYSQL_DB = extmail

130 SYS_MYSQL_HOST = localhost

131 SYS_MYSQL_SOCKET =/tmp/mysql. sock

In the master configuration file of apache, the virtual host section of extmail. Add two rows

Create a temporary directory for running and modify permissions

[Root @ mail ~] # Mkdir-pv/tmp/extman

Mkdir: created directory '/tmp/extman'

[Root @ mail ~] # Chown postfix. postfix/tmp/extman

Restart the apache server.

Login test Default Administrator Account: root@extmail.org password: extmail * 123 *

Http: // 10.1.1.100
