←手機掃碼閱讀     火星人 @ 2014-03-08 , reply:0


一、安裝前的準備工作:

0. 安裝DNS

# vim /etc/resolv.conf

search liuwei.com

nameserver 192.168.101.200

# vim /etc/sysconfig/network

HOSTNAME=mail.liuwei.com

# yum install bind bind-chroot caching-nameserver

# cd /var/named/chroot/etc/

# cp -p named.caching-nameserver.conf named.conf

# vim named.conf

# vim named.rfc1912.zones

# cd ../var/named/
Empire CMS,phome.net

# cp -p localhost.zone liuwei.com.db

# vim liuwei.com.db

# cp -p named.local 192.168.101.db

# vim 192.168.101.db

# rndc reload

# chkconfig named on

# service named start

# nslookup mail.a.org

# nslookup mail.liuwei.com

# nslookup 192.168.101.200

Empire CMS,phome.net

1、安裝所需的rpm包,這包括以下這些:

httpd, php, php-mysql, mysql, mysql-server, mysql-devel, openssl-devel, dovecot, perl-DBD-MySQL, tcl, tcl-devel, libart_lgpl, libart_lgpl-devel, libtool-ltdl, libtool-ltdl-devel, expect

2、關閉sendmail,並將它的隨系統自動啟動功能關閉:

# service sendmail stop

Empire CMS,phome.net

# chkconfig sendmail off

3、安裝以下開發所用到的rpm包組:

Development Libraries

Development Tools

Legacy Software Development

X Software Development

方法:

# yum grouplist all |less查看已安裝的組環境

4、啟動mysql資料庫,並給mysql的root用戶設置密碼:

# service mysqld start
Empire CMS,phome.net

# chkconfig mysqld on

# mysqladmin -u root password 'liuwei'

也可以

mysql>

---------------------------------授權本地用戶

SET PASSWORD FOR root@'localhost'=PASSWORD('liuwei');

SET PASSWORD FOR root@'127.0.0.1'=PASSWORD('liuwei');

FLUSH PRIVILEGES;

-------------------------------授權遠程用戶

GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'liuwei';

FLUSH PRIVILEGES;

二、安裝配置postfix

Empire CMS,phome.net

# groupadd -g 2525 postfix

# useradd -g postfix -u 2525 -s /sbin/nologin -M postfix

# groupadd -g 2526 postdrop

# useradd -g postdrop -u 2526 -s /bin/false -M postdrop

# tar -zxvf postfix-2.8.2.tar.gz -C /usr/src

# cd /usr/src

# cd postfix-2.8.2/

# make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/include/sasl -DUSE_TLS ' 'AUXLIBS=-L/usr/lib/mysql -lmysqlclient -lz -lm -L/usr/lib/sasl2 -lsasl2 -lssl -lcrypto'

# make

# make install

按照以下的提示輸入相關的路徑([]號中的是預設值,”]”后的是輸入值,省略的表示採用默認值)

  install_root: [/] /

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

  config_directory: [/etc/postfix] /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]

生成別名二進位文件,這個步驟如果忽略,會造成postfix效率極低:

# newaliases

2.進行一些基本配置,測試啟動postfix並進行發信

#vim /etc/postfix/main.cf

修改以下幾項為您需要的配置
Empire CMS,phome.net

myhostname = mail.liuwei.com

myorigin = $mydomain

mydomain = liuwei.com

mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain

mynetworks = 192.168.101.0/24, 127.0.0.0/8

說明:

myorigin參數用來指明發件人所在的域名;

mydestination參數指定postfix接收郵件時收件人的域名,即您的postfix系統要接收到哪個域名的郵件;

/var/lib/mysql/mysql.sock'

myhostname 參數指定運行postfix郵件系統的主機的主機名,默認情況下,其值被設定為本地機器名;

mydomain參數指定您的域名,默認情況下,postfix將myhostname的第一部分刪除而作為mydomain的值;

mynetworks 參數指定你所在的網路的網路地址,postfix系統根據其值來區別用戶是遠程的還是本地的,如果是本地網路用戶則允許其訪問;

inet_interfaces 參數指定postfix系統監聽的網路介面;

注意:

1、在postfix的配置文件中,參數行和註釋行是不能處在同一行中的;

2、任何一個參數的值都不需要加引號,否則,引號將會被當作參數值的一部分來使用;

3、每修改參數及其值后執行 postfix reload 即可令其生效;但若修改了inet_interfaces,則需重新啟動postfix;

4、如果一個參數的值有多個,可以將它們放在不同的行中,只需要在其後的每個行前多置一個空格即可;postfix會把第一個字元為空格或tab的文本行視為上一行的延續;

啟動postfix

# /usr/local/postfix/sbin/postfix start

# cd

# mkdir abc

# cd abc/

# cp /mnt/cdrom/Server/postfix-2.3.3-2.1.el5_2.i386.rpm ./

# rpm2cpio postfix-2.3.3-2.1.el5_2.i386.rpm |cpio -id

# cd etc

# cd rc.d/

# cd init.d/

# cp postfix /etc/init.d

# ll /etc/init.d/postfix

# service postfix start

# chkconfig -add postfix

# chkconfig --add postfix

# chkconfig postfix on

# 5、啟動saslauthd服務,並將其加入到自動啟動隊列:

# service saslauthd start

# chkconfig saslauthd on

連接postfix,驗正服務啟動狀況:

# telnet localhost 25

Trying 127.0.0.1...

Connected to localhost.localdomain (127.0.0.1).

Escape character is '^]'.

三、為postfix開啟基於cyrus-sasl的認證功能

使用以下命令驗正postfix是否支持cyrus風格的sasl認證,如果您的輸出為以下結果,則是支持的:

# /usr/local/postfix/sbin/postconf -a

cyrus

dovecot

#vim /etc/postfix/main.cf

添加以下內容:

############################CYRUS-SASL############################
Empire CMS,phome.net

broken_sasl_auth_clients = yes

smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject_invalid_hostname,reject_non_fqdn_hostname,reject_unknown_sender_domain,reject_non_fqdn_sender,reject_non_fqdn_recipient,reject_unknown_recipient_domain,reject_unauth_pipelining,reject_unauth_destination

smtpd_sasl_auth_enable = yes

smtpd_sasl_local_domain = $myhostname

smtpd_sasl_security_options = noanonymous

smtpd_banner = Welcome to our $myhostname ESMTP,Warning: Version not Available!

(#vim /usr/lib/sasl2/smtpd.conf)

添加如下內容:

pwcheck_method: saslauthd

mech_list: PLAIN LOGIN

啟動 sasl服務

chkconfig saslauthd on

chkconfig saslauthd on

讓postfix重新載入配置文件

# service postfix reload

# telnet localhost 25

Trying 127.0.0.1...

Connected to localhost.localdomain (127.0.0.1).

Escape character is '^]'.

220 Welcome to our mail.test.com ESMTP,Warning: Version not Available!

ehlo mail.test.com

250-mail.test.com

250-PIPELINING

250-SIZE 10240000

250-VRFY

250-ETRN

250-AUTH PLAIN LOGIN

250-AUTH=PLAIN LOGIN (請確保您的輸出以類似兩行)

250-ENHANCEDSTATUSCODES

250-8BITMIME

250 DSN

四、安裝Courier authentication library

# cd

# tar -jxvf courier-authlib-0.63.1.20111230.tar.bz2 -C /usr/src

# cd /usr/src

# cd courier-authlib-0.63.1.20111230/

#./configure --prefix=/usr/local/courier-authlib --sysconfdir=/etc --with-authmysql --with-mysql-libs=/usr/lib/mysql --with-mysql-includes=/usr/include/mysql --with-redhat --with-authmysqlrc=/etc/authmysqlrc --with-authdaemonrc=/etc/authdaemonrc --with-ltdl-lib=/usr/lib --with-ltdl-include=/usr/include

# make

# make install

# chmod 755 /usr/local/courier-authlib/var/spool/authdaemon

# cp /etc/authdaemonrc.dist /etc/authdaemonrc

# cp /etc/authmysqlrc.dist /etc/authmysqlrc

修改/etc/authdaemonrc 文件

authmodulelist="authmysql"

authmodulelistorig="authmysql"

daemons=10

編輯/etc/authmysqlrc 為以下內容,其中2525,2525 為postfix 用戶的UID和GID.

MYSQL_SERVER localhost

MYSQL_PORT 3306 (指定你的mysql監聽的埠,這裡使用默認的3306)

MYSQL_USERNAME extmail (這時為後文要用的資料庫的所有者的用戶名)

MYSQL_PASSWORD extmail (密碼)

MYSQL_SOCKET /var/lib/mysql/mysql.sock

MYSQL_DATABASE extmail

MYSQL_USER_TABLE mailbox

MYSQL_CRYPT_PWFIELD password

MYSQL_UID_FIELD '2525'

MYSQL_GID_FIELD '2525'

MYSQL_LOGIN_FIELD username

MYSQL_HOME_FIELD concat('/var/mailbox/',homedir)

MYSQL_NAME_FIELD name

MYSQL_MAILDIR_FIELD concat('/var/mailbox/',maildir)

# 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

# service courier-authlib start (啟動服務)

新建虛擬用戶郵箱所在的目錄,並將其許可權賦予postfix用戶:

#mkdir –pv /var/mailbox

#chown –R postfix /var/mailbox

接下來重新配置SMTP 認證,編輯 /usr/lib/sasl2/smtpd.conf ,確保其為以下內容:

pwcheck_method: authdaemond

log_level: 3

mech_list:PLAIN LOGIN

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

五、讓postfix支持虛擬域和虛擬用戶

1、編輯/etc/postfix/main.cf,添加如下內容:

########################Virtual Mailbox Settings########################

virtual_mailbox_base = /var/mailbox

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

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

virtual_alias_domains =

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

virtual_uid_maps = static:2525

virtual_gid_maps = static:2525

virtual_transport = virtual

maildrop_destination_recipient_limit = 1

maildrop_destination_concurrency_limit = 1

##########################QUOTA Settings########################

message_size_limit = 14336000

virtual_mailbox_limit = 20971520

virtual_create_maildirsize = yes

virtual_mailbox_extended = yes

virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_mailbox_limit_maps.cf

virtual_mailbox_limit_override = yes

virtual_maildir_limit_message = Sorry, the user's maildir has overdrawn his diskspace quota, please Tidy your mailbox and try again later.

virtual_overquota_bounce = yes

2、使用extman源碼目錄下docs目錄中的extmail.sql和init.sql建立資料庫:

# tar -zxvf extman-1.1.tar.gz

# cd extman-1.1/docs

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

# mysql -u root -p <extmail.sql

# mysql -u root -p <init.sql

# cp mysql* /etc/postfix/

3、授予用戶extmail訪問extmail資料庫的許可權

mysql -u root -p 進行驗證

mysql> GRANT all privileges on extmail.* TO extmail@localhost IDENTIFIED BY 'extmail';

mysql> GRANT all privileges on extmail.* TO extmail@127.0.0.1 IDENTIFIED BY 'extmail';

mysql>FLUSH PRIVILEGES; 讓設置的內容生效

service postfix restart

說明:啟用虛擬域以後,需要取消中心域,即註釋掉myhostname, mydestination, mydomain, myorigin幾個指令;當然,你也可以把mydestionation的值改為你自己需要的.

# vim /etc/postfix/main.cf

162 #mydestination = $myhostname, localhost.$mydomain, localhost,

$mydomain,

163 #mail.$mydomain, www.$mydomain, ftp.$mydomain
