poxtfix+dovecot+saslauthd+courier-authlib +mysql + extmail 完整虚拟邮箱系统部署

發(fā)布時間:2023/11/29 33 豆豆
生活随笔 收集整理的這篇文章主要介紹了 poxtfix+dovecot+saslauthd+courier-authlib +mysql + extmail 完整虚拟邮箱系统部署 小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.


所需軟件:

平臺,RHEL5.8

postfix-2.9.15?

dovecot系統(tǒng)自帶

courier-authlib-0.62.4高與0.64本平臺可能無法使用

mysql 5.7 含:

????mysql-5.7.12-1.el5.x86_64.rpm?

????mysql-community-client-5.7.12-1.el5.x86_64.rpm

????mysql-community-common-5.7.12-1.el5.x86_64.rpm

????mysql-community-devel-5.7.12-1.el5.x86_64.rpm

????mysql-community-libs-5.7.12-1.el5.x86_64.rpm

????mysql-community-libs-compat-5.7.12-1.el5.x86_64.rpm

????mysql-community-server-5.7.12-1.el5.x86_64.rpm

可以到:http://dev.mysql.com/downloads/mysql/?上面上載

extmail-1.2 +?extman-1.1

附加軟件包(可以yum install直接安裝):

httpd, mysql-devel, openssl-devel, libtool-ltdl-devel,libtool-ltdl,perl-DBD-MySQL, tcl, tcl-devel, libart_lgpl, libart_lgpl-devel , expect,cyrus-sasl.x86_64,cyrus-sasl-devel,cyrus-sasl-lib,cyrus-sasl-plain

并安裝以下開發(fā)所用到的rpm包組:

Development Libraries

Development Tools

方法:

yum groupinstall "Development Libraries" "Development Tools"

一、準備工作:

1、關(guān)閉或卸載sendmail,并將它的隨系統(tǒng)自動啟動功能關(guān)閉:

service sendmail stop

chkconfig sendmail off

rpm -e --nodeps?sendmail?

2、如果要用mysql 5.5/5.7等高版本mysql,請把系統(tǒng)自帶的mysql相關(guān)軟件包也卸載了,以確保不沖突

對于5.1以上的版本,系統(tǒng)的存儲引擎為InnoDB,extman的腳本可能要修改,如果不想麻煩,可以用系統(tǒng)自帶的,可能不用修改sql腳本


3、啟動saslauthd服務(wù),并將其加入到自動啟動隊列:

# service saslauthd start

# chkconfig saslauthd on


二、安裝配置postfix


# groupadd -g 2525 postfix

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

# groupadd -g 2526 postdrop

# useradd -g postdrop -u 2526 -s /sbin/nologin -M postdrop

# cd postfix-2.9.15

1、編譯安裝

# 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(guān)的路徑([]號中的是缺省值,”]”后的是輸入值,省略的表示采用默認值)


  install_root: [/] /

  tempdir: [/root/postfix-2.9.3] /tmp/postfix

  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/html/postfix?

? ? manpages: [/usr/local/man]

? ? readme_directory: [no]


生成別名二進制文件:

# ?newaliases

還有不要忘記了執(zhí)行這個,否則啟動可能出錯報:

warning: unable to look up public/pickup: No such file or directory

warning: unable to look up public/pickup: No such file or directory

fatal: the Postfix mail system is not running

fatal: scan_dir_push: open directory maildrop: Permission denied

fatal: Postfix integrity check failed!

#post-install set-permissions

2、做簡單配置

# vim /etc/postfix/main.cf

修改以下幾項為您需要的配置,注意,要頂格寫,否則系統(tǒng)會認為是上一行的延續(xù)

myhostname = mail.test.com

myorigin = test.com

mydomain = test.com

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

mynetworks = 192.168.1.0/24, 127.0.0.0/8

保存退出

3、為postfix編寫啟動服務(wù)腳本/etc/rc.d/init.d/postfix:

#!/bin/bash

#

# postfix ? ? ?Postfix Mail Transfer Agent

#

# chkconfig: 2345 80 30

# description: Postfix is a Mail Transport Agent, which is the program \

# ? ? ? ? ? ? ?that moves mail from one machine to another.

# processname: master

# pidfile: /var/spool/postfix/pid/master.pid

# config: /etc/postfix/main.cf

# config: /etc/postfix/master.cf


# Source function library.

. /etc/rc.d/init.d/functions


# Source networking configuration.

. /etc/sysconfig/network


# Check that networking is up.

[ $NETWORKING = "no" ] && exit 3


[ -x /usr/sbin/postfix ] || exit 4

[ -d /etc/postfix ] || exit 5

[ -d /var/spool/postfix ] || exit 6


RETVAL=0

prog="postfix"


start() {

# Start daemons.

echo -n $"Starting postfix: "

? ? ? ? /usr/bin/newaliases >/dev/null 2>&1

/usr/sbin/postfix start 2>/dev/null 1>&2 && success || failure $"$prog start"

RETVAL=$?

[ $RETVAL -eq 0 ] && touch /var/lock/subsys/postfix

? ? ? ? echo

return $RETVAL

}


stop() {

? # Stop daemons.

echo -n $"Shutting down postfix: "

/usr/sbin/postfix stop 2>/dev/null 1>&2 && success || failure $"$prog stop"

RETVAL=$?

[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/postfix

echo

return $RETVAL

}


reload() {

echo -n $"Reloading postfix: "

/usr/sbin/postfix reload 2>/dev/null 1>&2 && success || failure $"$prog reload"

RETVAL=$?

echo

return $RETVAL

}


abort() {

/usr/sbin/postfix abort 2>/dev/null 1>&2 && success || failure $"$prog abort"

return $?

}


flush() {

/usr/sbin/postfix flush 2>/dev/null 1>&2 && success || failure $"$prog flush"

return $?

}


check() {

/usr/sbin/postfix check 2>/dev/null 1>&2 && success || failure $"$prog check"

return $?

}


restart() {

stop

start

}


# See how we were called.

case "$1" in

? start)

[ -f /var/lock/subsys/postfix ] && restart || :

;;

? *)

echo $"Usage: $0 {start|stop|restart|reload|abort|flush|check|status|condrestart}"

exit 1

esac


exit $?


# END

4、賦予執(zhí)行權(quán)限并啟動postfix:

# chmod +x /etc/rc.d/init.d/postfix


添加至服務(wù)列表:

# chkconfig --add postfix


開機自動啟動:

# chkconfig postfix on


使用腳本重新啟動服務(wù):

# service postfix restart


5、為postfix開啟基于cyrus-sasl的認證功能


驗正postfix是否支持cyrussasl認證,確保出出以下結(jié)果:

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

cyrus

dovecot


#vi /etc/postfix/main.cf

############CYRUS-SASL ###################

smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination

smtpd_sasl_auth_enable = yes

smtpd_sasl_local_domain = $myhostname

smtpd_sasl_security_options = noanonymous

smtpd_sasl_path = smtpd

smtpd_banner = ESMTP,Warning:system not work!


# vi /usr/lib64/sasl2/smtpd.conf

添加如下內(nèi)容:

pwcheck_method: saslauthd

mech_list: PLAIN LOGIN

重啟postfix并測試

#/usr/sbin/postfix restart

# 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:system not work!

ehlo mail.magedu.com

250-mail.magedu.com

250-PIPELINING

250-SIZE 10240000

250-VRFY

250-ETRN

250-AUTH PLAIN LOGIN

250-AUTH=PLAIN LOGIN ? ? ? (請確保有這兩行輸出)

250-ENHANCEDSTATUSCODES

250-8BITMIME

250 DSN


三、安裝Courier authentication library并配置其通過mysql進行驗證郵箱用戶

1、安裝Courier authentication library

# tar xf courier-authlib-0.62.4.tar.bz2

# cd courier-authlib-0.62.4

./configure \

? ? --prefix=/usr/local/courier-authlib \

? ? --sysconfdir=/etc \

? ? --without-authpam \

? ? --without-authshadow \

? ? --without-authvchkpw \

? ? --without-authpgsql \

? ? --with-authmysql=yes \

? ? --with-mysql-libs=/usr/lib64/mysql \

? ? --with-mysql-includes=/usr/include/mysql \

? ? --with-redhat \

? ? --with-authmysqlrc=/etc/authmysqlrc \

? ? --with-authdaemonrc=/etc/authdaemonrc \

? ? --with-mailuser=postfix \

? ? --with-mailgroup=postfix \

? ? --with-ltdl-lib=/usr/lib64 \

? ? --with-ltdl-include=/usr/include

注意:這里是rpm包版的mysql庫文件路徑,如果不是rpm包安裝的mysql,請用確保你的with-mysql-libs、with-mysql-includes的路徑是正確的,還有,一定要把--with-authmysql=yes寫上,否則,編譯出來的一樣不把持mysql

# 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" --一定要確保這個列表中有autymysql出現(xiàn),否則不支持mysql驗證

authmodulelistorig="authmysql"

daemons=10

2、配置mysql進行郵件用戶驗證

編輯/etc/authmysqlrc 為以下內(nèi)容,其中2525,2525 為postfix 用戶的UID和GID。

MYSQL_SERVER localhost

MYSQL_PORT 3306????????--mysql監(jiān)聽端口,默認的3306

MYSQL_USERNAME ?extmail????--數(shù)據(jù)庫的所有者的用戶名

MYSQL_PASSWORD extmail?????--密碼,根據(jù)自已的設(shè)置填寫

MYSQL_SOCKET ?/var/lib/mysql/mysql.sock --rpm包版的sock在這里

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)


3、啟動腳本


# cp courier-authlib.sysvinit /etc/rc.d/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


4、配置postfix通過courier-authlib驗證用戶


新建虛擬用戶郵箱目錄,并將其權(quán)限賦予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/lib64/sasl2/smtpd.conf ,確保其為以下內(nèi)容:

pwcheck_method: authdaemond

log_level: 3

mech_list:PLAIN LOGIN

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


四、讓postfix支持虛擬域和虛擬用戶


1、編輯/etc/postfix/main.cf,添加如下內(nèi)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

注:/etc/postfix/mysql_virtual_*.cf 來自extman-1.1/docs,當(dāng)然,我們需要配置其數(shù)據(jù)庫連接用到的用戶名,密碼


2、配置extman

用源碼目錄下docs目錄中的extmail.sql和init.sql建立數(shù)據(jù)庫:

mysql 5.0 可以直接使用?extmail.sql初始化數(shù)據(jù)庫,5.1以上要把數(shù)據(jù)庫存儲引擎修改為InnoDB,5.7不用指定存儲引擎,還要在my.cnf中加上sql-mode='IGNORE',并對manager表的sql做簡單修改:

如下:

CREATE TABLE manager (

? username varchar(255) NOT NULL default '',

? password varchar(255) NOT NULL default '',

? type varchar(64) NOT NULL default 'postmaster',

? uid varchar(255) NOT NULL default '',

? name varchar(255) NOT NULL default '',

? question text ,

? answer text ,

? disablepwdchange smallint(1),

? createdate datetime NOT NULL ,

? expiredate DATE NOT NULL default '2030-12-30',

? active tinyint(1) NOT NULL default '1',

? PRIMARY KEY ?(username),

? KEY username (username)

) COMMENT='Ext/Webman - Admin Accounts';

還有,5.7上的建用戶、建庫一定要用create user、create database語句,INSERT INTO user、INSERT INTO db?語句不可用,還要修改extmail.sql腳本

# 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數(shù)據(jù)庫

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

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

注:啟用虛擬域,要取消中心域,注釋掉myhostname, mydestination, mydomain, myorigin幾個指令


4、配置dovecot使用mysql驗證用戶


# vi /etc/dovecot.conf

mail_location = maildir:/var/mailbox/%d/%n/Maildir


auth default {

? ? mechanisms = plain

? ? passdb sql {

? ? ? ? args = /etc/dovecot-mysql.conf

? ? }

? ? userdb sql {

? ? ? ? args = /etc/dovecot-mysql.conf

? ? }


# vim /etc/dovecot-mysql.conf ? ? ? ? ? ? ? ??

driver = mysql

connect = host=/tmp/mysql.sock dbname=extmail user=extmail password=不要照抄

default_pass_scheme = CRYPT

password_query = SELECT username AS user,password AS password FROM mailbox WHERE username = '%u' ? ? ? ? ? ? ? ? ? ? ? ? ? ?

user_query = SELECT maildir, uidnumber AS uid, gidnumber AS gid FROM mailbox WHERE username = '%u'


啟動dovecot服務(wù):


# service dovecot start

# chkconfig dovecot on


五、安裝Extmail-1.2


1、安裝

# tar zxvf extmail-1.2.tar.gz

# mkdir -pv /var/www/extsuite

# mv extmail-1.2 /var/www/extsuite/extmail

# cp /var/www/extsuite/extmail/webmail.cf.default ?/var/www/extsuite/extmail/webmail.cf


2、配置

#vi /var/www/extsuite/extmail/webmail.cf


部分修改選項的說明:


SYS_MESSAGE_SIZE_LIMIT = 5242880

用戶可以發(fā)送的最大郵件


SYS_USER_LANG = en_US

語言選項,可改作:

SYS_USER_LANG = zh_CN


SYS_MAILDIR_BASE = /home/domains

此處即為您在前文所設(shè)置的用戶郵件的存放目錄,可改作:

SYS_MAILDIR_BASE = /var/mailbox


SYS_MYSQL_USER = db_user

SYS_MYSQL_PASS = db_pass

以上兩句句用來設(shè)置連接數(shù)據(jù)庫服務(wù)器所使用用戶名、密碼和郵件服務(wù)器用到的數(shù)據(jù)庫,這里修改為:

SYS_MYSQL_USER = extmail

SYS_MYSQL_PASS = 你的密碼


SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock --rpm包版的sock在這里


SYS_MYSQL_HOST = localhost

數(shù)據(jù)庫服務(wù)器主機名


SYS_MYSQL_TABLE = mailbox

SYS_MYSQL_ATTR_USERNAME = username

SYS_MYSQL_ATTR_DOMAIN = domain

SYS_MYSQL_ATTR_PASSWD = password


以上用來指定驗正用戶登錄里所用到的表,以及用戶名、域名和用戶密碼分別對應(yīng)的表中列的名稱;這里默認即可


SYS_AUTHLIB_SOCKET = /var/spool/authdaemon/socket

此句用來指明authdaemo socket文件的位置,這里修改為:

SYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socket



3、加入apache


由于extmail要進行本地郵件的投遞操作,故必須將運行apache服務(wù)器用戶的身份修改為您的郵件投遞代理的用戶;本例中打開了apache服務(wù)器的suexec功能,故使用以下方法來實現(xiàn)虛擬主機運行身份的指定。此例中的MDA為postfix自帶,因此將指定為postfix用戶:

<VirtualHost *:80>

ServerName mail.magedu.com

DocumentRoot /var/www/extsuite/extmail/html/

ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi

Alias /extmail /var/www/extsuite/extmail/html

SuexecUserGroup postfix postfix

</VirtualHost>


修改 cgi執(zhí)行文件屬主為apache運行身份用戶:

# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/


如果您沒有打開apache服務(wù)器的suexec功能,也可以使用以下方法解決:

# vi /etc/httpd/conf/httpd.conf

User postfix

Group postfix


<VirtualHost *:80>

ServerName mail.magedu.com

DocumentRoot /var/www/extsuite/extmail/html/

ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi

Alias /extmail /var/www/extsuite/extmail/html

</VirtualHost>


4、依賴關(guān)系的解決


extmail將會用到perl的Unix::syslogd功能,您可以去http://search.cpan.org搜索下載原碼包進行安裝。

# tar zxvf Unix-Syslog-0.100.tar.gz

# cd Unix-Syslog-0.100

# perl Makefile.PL

# make

# make install


啟動apache服務(wù)

# service httpd start

# chkconfig httpd on


六、安裝Extman-1.1


# tar zxvf ?extman-1.1.tar.gz

# mv extman-1.1 /var/www/extsuite/extman


修改配置文件以符合本例的需要:

# cp /var/www/extsuite/extman/webman.cf.default ?/var/www/extsuite/extman/webman.cf

# vi /var/www/extsuite/extman/webman.cf


SYS_MAILDIR_BASE = /home/domains

此處即為您在前文所設(shè)置的用戶郵件的存放目錄,可改作:

SYS_MAILDIR_BASE = /var/mailbox


SYS_DEFAULT_UID = 1000

SYS_DEFAULT_GID = 1000

此兩處后面設(shè)定的ID號需更改為前而創(chuàng)建的postfix用戶和postfix組的id號,我們使用的是2525,因此,上述兩項需要修改為:

SYS_DEFAULT_UID = 2525

SYS_DEFAULT_GID = 2525


SYS_MYSQL_USER = webman

SYS_MYSQL_PASS = webman

修改為:

SYS_MYSQL_USER = extmail

SYS_MYSQL_PASS = 你的密碼,不要照抄


SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock --rpm包版的sock在這里


而后修改cgi目錄的屬主:

# chown -R postfix.postfix /var/www/extsuite/extman/cgi/


在apache的主配置文件中Extmail的虛擬主機部分,添加如下兩行:

ScriptAlias /extman/cgi /var/www/extsuite/extman/cgi

Alias /extman /var/www/extsuite/extman/html


創(chuàng)建其運行時所需的臨時目錄,并修改其相應(yīng)的權(quán)限:

#mkdir ?-pv ?/tmp/extman

#chown postfix.postfix ?/tmp/extman


修改

SYS_CAPTCHA_ON = 1

SYS_CAPTCHA_ON = 0


好了,到此為止,重新啟動apache服務(wù)器后,您的Webmail和Extman已經(jīng)可以使用了,可以在瀏覽器中輸入指定的虛擬主機的名稱進行訪問,如下:

http://ip/extmail


選擇管理即可登入extman進行后臺管理了。默認管理帳號為:root@extmail.org ?密碼為:extmail*123*


七、配置Mailgraph_ext,使用Extman的圖形日志:(下面所需的軟件包面要自己下載)


接下來安裝圖形日志的運行所需要的軟件包Time::HiRes、File::Tail和rrdtool,其中前兩個包您可以去http://search.cpan.org搜索并下載獲得,后一個包您可以到 http://oss.oetiker.ch/rrdtool/pub/?M=D下載獲得; 注意安裝順序不能改換。


安裝Time::HiRes

#tar zxvf Time-HiRes-1.9707.tar.gz

#cd Time-HiRes-1.9707

#perl Makefile.PL

#make

#make test

#make install


安裝File::Tail

#tar zxvf File-Tail-0.99.3.tar.gz

#cd File-Tail-0.99.3

#perl Makefile

#make

#make test

#make install


安裝rrdtool-1.2.23-1.el5.rf.x86_64.rpm依賴以下兩個包,要三個一起安裝才行

rrdtool-devel-1.2.23-1.el3.rf.x86_64.rpm

perl-rrdtool-1.2.23-1.el4.rf.x86_64.rpm

rpm -iv *rrdtool*


復(fù)制mailgraph_ext到/usr/local,并啟動之

# cp -r /var/www/extsuite/extman/addon/mailgraph_ext ?/usr/local

# /usr/local/mailgraph_ext/mailgraph-init start


啟動cmdserver(在后臺顯示系統(tǒng)信息)

# /var/www/extsuite/extman/daemon/cmdserver --daemon


添加到自動啟動隊列

# echo “/usr/local/mailgraph_ext/mailgraph-init start” >> /etc/rc.d/rc.local

# echo “/var/www/extsuite/extman/daemon/cmdserver -v -d” >> /etc/rc.d/rc.local?


使用方法: 等待大約15分鐘左右,如果郵件系統(tǒng)有一定的流量,即可登陸到extman里,點“圖形日志”即可看到圖形化的日志。具體每天,周,月,年的則點擊相應(yīng)的圖片進入即可。


八、對于smtp、pop3f進行ssl加密這里不再說明,要想接受來自公網(wǎng)上的郵件,我們把25號端口映射到防火墻上即可,如果想用foxmail、outlook等MUA來收發(fā)郵件,把110(pop3)、995(pops)、25(smtp)、465(smtps)映射出去,注意:110、25是明文件傳輸密碼的
