Postfix Server Setup

Implement Postfix implementation Extmail interface

Environment:

Host 1:172.16.115.169 (DNS server)

Host 2:172.16.115.161 (mail server)

On Host 1:

1. Build a DNS server

Yum install-y bind

1.1 Edit Master configuration vim /etc/named.conf

# Listen to all IP on the machine, allow the client to query

Options {

listen-on Port : (any;};

Listen-on-v6 Port 53 {:: 1;};

Directory "/var/named";

Dump-file "/var/named/data/cache_dump.db";

Statistics-file "/var/named/data/named_stats.txt";

Memstatistics-file "/var/named/data/named_mem_stats.txt";

allow-query { any;};

recursion Yes;

Dnssec-enable Yes;

Dnssec-validation Yes;

1.2 Edit Domain profile vim /etc/named.rfc1912.zones

#正向解析和反向解析

Zone " huangzp2.com "in {

Type master;

file " huangzp2.com ";

allow-update {none;};

};

Zone " 115.16.172. In-addr.arpa "in {

Type master;

file " Huangzp2.empty ";

allow-update {none;};

};

1.3 Editing a data configuration file

cd/var/named/

1.3.1 Forward parsing data records

Cp-p Named.localhost huangzp2.com

Or

CP Named.localhost Huangzp2.com;chown named huangzp2.com

Vim huangzp2.com

# Add forward parse record

$TTL 1D

@ in SOA huangzp2.com. Rname.invalid. (

0; Serial

1D; Refresh

1H; Retry

1W; Expire

3H); Minimum

NS dns.huangzp2.com.

MX 3 mail.huangzp2.com.

DNS A 172.16.115.169

Mail A 172.16.115.161

1.3.2 Reverse parsing data records

Cp-p Named.empty Huangzp2.empty

Vim Huangzp2.empty

# Anti-parsing record

$TTL 3H

@ in SOA huangzp2.com. Rname.invalid. (

0; Serial

1D; Refresh

1H; Retry

1W; Expire

3H); Minimum

NS dns.huangzp2.com.

169 PTR dns.huangzp2.com.

161 PTR mail.huangzp2.com.

2. Start named

Service named restart

On Host 2:

1. Test mail Domain resolution

Vim/etc/sysconfig/network-scripts/ifcfg-eth0

# Setting up a DNS server

Device=eth0

hwaddr=00:0c:29:cb:db:6c

Type=ethernet

uuid=05904c7e-119a-4e58-8b65-26d344366982

Onboot=yes

Nm_controlled=yes

Bootproto=static

ipaddr=172.16.115.161

netmask=255.255.0.0

gateway=172.16.0.199

dns1=172.16.115.169

dns=202.96.134.133

# Test forward parsing

[email protected] docs]# nslookup mail.huangzp2.com

server:172.16.115.169

address:172.16.115.169#53

Name:mail.huangzp2.com

address:172.16.115.161

# Test Reverse resolution

[email protected] docs]# nslookup 172.16.115.161

server:172.16.115.169

address:172.16.115.169#53

161.115.16.172.in-addr.arpa name = mail.huangzp2.com.

2. Installation Kit

Yum install-y MySQL mysql-server mailx

Service mysqld Start

3. Installing Extmail and Extman

Download extmail-1.2.tar.gz

Extman-1.1.tar.gz

Extract

TAR-ZXF extmail-1.2.tar.gz-c/var/www/extsuite/

TAR-ZXF extmman-1.1.tar.gz-c/var/www/extsuite/

Renamed

MV extmail-1.2 Extmail

MV extman-1.1 Extman

4. Import the database template file

Enter directory:

/var/www/extsuite/extman/docs

4.1 Copy configuration file:

CP mysql_virtual_alias_maps.cf/etc/postfix/

CP mysql_virtual_domains_maps.cf/etc/postfix/

CP mysql_virtual_mailbox_maps.cf/etc/postfix/

CP mysql_virtual_sender_maps.cf/etc/postfix/

4.2 Modifying the database initial data:

Vim/var/www/extsuite/extman/docs/init.sql

# Replace domain name

: 1, $s/extmail.org/huangzp2.com/g

# Change Password

INSERT into ' manager ' VALUES (' [email protected] ', '123456', ' admin ', ' root ', ' Super User ', ' my Question ', ' My Answer ', ' 0 ', ' 2007-02-14 15:10:04 ', ' 2010-11-08 ', 1);

4.3 Importing a database template

MySQL < Extmail.sql

MySQL < Init.sql

5. Create virtual user mappings for real users

Useradd-u Vmail

6. Modify the main postfix configuration file

Vim/etc/postfix/main.cf

# Service to all addresses

Inet_interfaces = All

#inet_interfaces = $myhostname

#inet_interfaces = $myhostname, localhost

#inet_interfaces = localhost

# Enable IPv4, and IPV6 if supported

Inet_protocols = All

# The location where the message is saved; The user and group ID used to receive the message; Add the specified configuration file

virtual_mailbox_base = /home/vmail

virtual_uid_maps = static:600

virtual_gid_maps = static:600

Virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf

Virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf

Virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf

7. Start Postfix

Service Postfix start

Netstat-anpt

8. e-mail test

to send a message:

echo "HI" |mail-s test [email protected]

To view the contents of the generated catalog:

# support is an alias for postmaster

Ls/home/vmail/huangzp2.com/postmaster/maildir/new

9. Installing and configuring Dovecot (MRA)

Description: Provide a search function

Yum install-y dovecot Dovecot-mysql

9.1 Modifying the configuration file:

vim/etc/dovecot/conf.d/10-mail.conf

# Set the location for receiving messages

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

# The virtual user ID number of the receiving message starts at 600

First_valid_uid = 600

9.2 Modifying the configuration file:

vim/etc/dovecot/conf.d/10-auth.conf

# Receive Email authentication method database Authentication

!include Auth-system.conf.ext

!include Auth-sql.conf.ext

9.3 Copy and edit the database validation template configuration file

cp/usr/share/doc/dovecot-2.0.9/example-config/dovecot-sql.conf.ext /etc/dovecot

Edit the configuration file:

Vim/etc/dovecot/dovecot-sql.conf.ext

# Set Database type is MySQL

Driver = MySQL

# Connection to the database and default encryption method

Connect = host=localhost dbname=extmail user=extmail password=extmail

Default_pass_scheme = MD5

# Ways to query passwords and users

Password_query = \

SELECT username, domain, password \

From mailbox WHERE username = '%u ' and domain = '%d '

User_query = SELECT Maildir, as UID, as GID from mailbox WHERE username = '%u '

9.4 Start Dovecot

Service Dovecot Start

10. Test for receiving mail

Description: Indicates that Dovecot is able to authenticate with MySQL (Postmaser user's username and password) only if the authentication is successful, it can log in and view the contents of the message.

[[email protected] docs]# telnet mail.huangzp2.com

11. Installing and configuring the Web server

Yum Install-y httpd

11.1 Editing a configuration file

Vim/etc/httpd/conf/httpd.conf

# Turn on the virtual host

Namevirtualhost *:80

# Invoke scripts, set directory aliases, invoke scripts to run users and groups

12. Set the CGI directory permissions for Extmail and edit the configuration file

# permissions; Change template profile to master configuration profile

Cd/var/www/extsuite/extmail

Chown-r Vmail.vmail cgi/

CP Webmail.cf.default WEBMAIL.CF
