postfix+mysql+maildrop+extman+extmail

安装系统时软件包只选：

base

development libraries

development tools

editors

text-base internet

 1.mysql安装与配置：

(1).mysql安装：

# tar -zxvf mysql-5.1.49.tar.gz

# cd mysql-5.1.49

# groupadd mysql

# useradd -g mysql -s /sbin/nologin -M mysql

#./configure --prefix=/usr/local/app/mysql5 --with-charset=gbk   --with-extra-charsets=all --enable-thread-safe-client --enable-local-infile --with-low-memory

如果报错：/bin/rm: cannot remove `libtoolt': No such file or directory，执行：

# autoreconf --force --install

# libtoolize --automake --force

# automake --force --add-missing

然后再执行configure

#make

#make install

(2).启动并添加到开机自启动：

# /usr/local/app/mysq5/bin/mysqld_safe --user=mysql &

# cp support-files/mysql.server  /etc/rc.d/init.d/mysqld

# chmod 755 /etc/rc.d/init.d/mysqld

# chkconfig --add mysqld

# chkconfig  --levels  345  mysqld  on

(3).配置库文件搜索路径：

# echo "/usr/local/app/mysql5/lib/mysql">>/etc/ld.so.conf

# ldconfig

#echo "export PATH=$PATH:/usr/local/app/mysql5/bin">>/etc/profile

#source /etc/profile

(4).添加root密码

# /usr/local/app/mysql5/bin/mysqladmin -u root password "xxxxx"

 

2.安装apache

安装Apache有两个要注意的地方，因为我这里用的Postfix的后台管理是extman这个程序，而它是通过CGI的方式来进行管理的，所以这里启用了suexec的功能，还有一个是关于网站的存放路径的，如果不指定，那么在启用suexec后会出现 suexec-docroot的错误。

(1)安装apache

#tar -jxvf httpd-2.2.9.tar.bz2

#cd httpd-2.2.9

#./configure --prefix=/usr/local/app/apache2 --enable-so --enable-rewrite --enable-mods-shared=all --enable-suexec --with-suexec-caller=daemon --with-suexec-docroot=/var/www

#make

#make install

(2)修改apache配置文件

#vi /usr/local/app/apahce2/conf/httpd.conf  

找到DocumentRoot “/usr/local/apache2/htdocs”

修改为：DocumentRoot “/var/www”(后文中我们还会注释掉此行，以启用虚拟主机)

 

找到<Directory “/usr/local/apache2/htdocs”>

修改为：<Directory “/var/www”>

 

找到

<Directory />

Options FollowSymLinks

AllowOverride None

Order deny,allow

Deny from all        //这句改为Allow from all

</Directory>

 

启动apache

#/usr/local/apache2/bin/apachectl start

 

(3)添加系统服务和自启动

#echo "/usr/local/app/apahce2/bin/apachectl start">>/etc/rc.d/rc.local

 

3.安装PHP

(1)安装PHP

# tar -zxvf php-5.2.6.tar.gz

# cd php-5.2.6

#./configure --prefix=/usr/local/app/php5 --with-apxs2=/usr/local/app/apahce2/bin/apxs --with-mysql=/usr/local/app/mysql5/ --with-mysqli=/usr/local/app/mysql5/bin/mysql_config --with-config-file-path=/usr/local/app/php5 --with-zlib --enable-mbstring=all

# make && make install

# cp php.ini-dist /usr/local/php/php.ini

 

(2)配置PHP

# vi /usr/local/apache2/conf/httpd.conf

添加：

AddType application/x-httpd-php .php

AddType application/x-httpd-php .php3

AddType application/x-httpd-php .phtml

 

找到DirectoryIndex index.html

修改为DirectoryIndex index.html index.php

 

(3)重新启动apache

# /usr/local/app/apahce2/bin/apachectl stop

# /usr/local/app/apahce2/bin/apachectl start

 

4、  安装courier-authlib

(1)首先需要安装expect：

yum install expect

(2)安装courier-authlib

#groupadd -g 1000 vmail

#useradd -g 1000 -u 1000 -M -s /sbin/nologin vmail

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

# cd courier-authlib-0.62.4

#./configure --prefix=/usr/local/app/courier-authlib --without-stdheaderdir --sysconfdir=/etc --without-authuserdb --without-authpam --without-authldap --without-authpwd --without-authshadow --without-authvchkpw --without-authpgsql --without-authcustom --with-authmysql --with-mysql-libs=/usr/local/app/mysql5/lib/mysql/ --with-mysql-includes=/usr/local/app/mysql5/include/mysql/ --with-redhat --with-mailuser=vmail --with-mailgroup=vmail

# make && make install

# make install-migrate

# make install-configure

更新lib库文件搜索路径

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

# ldconfig

(3)修改配置文件

# vi /etc/authlib/authdaemonrc

authmodulelist="authmysql"

authmodulelistorig="authmysql"

daemons=10

DEBUG_LOGIN=2

 

 

# vi  /etc/authlib/authmysqlrc

修改以下内容

MYSQL_SERVER            localhost

MYSQL_USERNAME          extmail

MYSQL_PASSWORD          extmail

MYSQL_SOCKET            /tmp/mysql.sock 

MYSQL_PORT              3306

MYSQL_DATABASE          extmail

MYSQL_USER_TABLE        mailbox

MYSQL_CRYPT_PWFIELD     password

MYSQL_UID_FIELD         "1000"

MYSQL_GID_FIELD         "1000"

MYSQL_LOGIN_FIELD       username

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

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

MYSQL_QUOTA_FIELD 　  concat(quota,"S")

                  

(4)启动及加入到自动运行队列

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

# chmod 755 /etc/rc.d/init.d/courier-authlib

# chkconfig --add courier-authlib

# chkconfig courier-authlib on

# service courier-authlib start

# chmod a+x /usr/local/courier-authlib/var/spool/authdaemon

 

5.安装courier-imap

(1)安装courier-imap

# tar -jxvf courier-imap-4.8.0.tar.bz2 

# cd courier-imap-4.8.0

#./configure --prefix=/usr/local/app/courier-imap --with-redhat --enable-unicode --disable-root-check --with-trashquota --without-ipv6 COURIERAUTHCONFIG="/usr/local/app/courier-authlib/bin/courierauthconfig"

# make && make install

# make install-configure

(2)编辑配置文件启用pop3及imap

# vi /usr/local/courier-imap/etc/pop3d

修改POP3DSTART=NO

POP3DSTART=YES

# vi /usr/local/courier-imap/etc/imapd

修改IMAPDSTART=NO

IMAPDSTART=YES

(3)启动及加入自动运行队列

# cp courier-imap.sysvinit /etc/rc.d/init.d/courier-imapd

# chmod 755 /etc/rc.d/init.d/courier-imapd

# chkconfig --add courier-imapd

# chkconfig courier-imapd on

# service courier-imapd start

 

6.安装cyrus-sasl

(1)先卸载本机自带的sasl

# rpm -qa |grep cyrus-sasl |xargs rpm -e --nodeps

# rm -rf /usr/lib/sasl

# rm -rf /usr/lib/sasl2

(2)安装cyrus-sasl

# tar -zxvf cyrus-sasl-2.1.22.tar.gz

# cd cyrus-sasl-2.1.22

#./configure --prefix=/usr/local/app/sasl2 --enable-plain --disable-sample --disable-digest --enable-login --enable-sql --disable-anon --disable-ntlm --disable-gssapi --disable-krb4 --disable-otp --disable-srp --disable-srp-setpass --with-mysql=/usr/local/app/mysql5/ --with-mysql-includes=/usr/local/app/mysql5/include/mysql/ --with-mysql-libs=/usr/local/app/mysql5/lib/mysql/ --with-authdaemond=/usr/local/app/courier-authlib/var/spool/authdaemon/socket

# make && make install

(3)共享链接库

# ln -sv /usr/local/app/sasl2/lib/*  /usr/lib

postfix2.3以后的版本会分别在/usr/local/lib和/usr/local/include中搜索sasl库文件及头文件，故还须将其链接至此目录中：

# ln -sv /usr/local/app/sasl2/lib/*  /usr/local/lib

# ln -sv /usr/local/app/sasl2/include/sasl/*  /usr/local/include

# echo "/usr/local/app/lib">>/etc/ld.so.conf

# ldconfig

(4)建立smtpd用户认证的配置文件

# vi /usr/local/lib/sasl2/smtpd.conf

pwcheck_method: authdaemond

mech_list: plain login

log_level:3

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

(5)创建运行时需要的目录

# mkdir -pv /var/state/saslauthd   

(6)启动并测试

# /usr/local/sbin/saslauthd -a shadow pam

# /usr/local/sbin/testsaslauthd -u root -p xxttest  // xxttest  为root的密码

(7)开机自动启动

# echo "/usr/local/app/sasl2/sbin/saslauthd -a shadow pam">>/etc/rc.local

 

 

7.安装postfix

(1)首先卸载系统自带的sendmail

# service sendmail stop

# rpm -qa |grep sendmail |xargs rpm -e –-nodeps

(2)添加用户和安装

# groupadd -g 1005 postfix

# useradd -g 1005 -u 1005 -M -s /sbin/nologin postfix

# groupadd -g 1006 postdrop

# useradd -g 1006 -u 1006 -M -s /sbin/nologin postdrop

# tar -zxvf postfix-2.6.5.tar.gz

# cd postfix-2.6.5

# make makefiles "CCARGS=-DHAS_MYSQL -I/usr/local/app/mysql5/include/mysql -DUSE_CYRUS_SASL -DUSE_SASL_AUTH -I/usr/local/incude/sasl" "AUXLIBS=-L/usr/local/app/mysql5/lib/mysql -lmysqlclient -lz -lm -L/usr/local/lib/ -lsasl2"

# make

# make install

(3)按照以下的提示输入相关的路径([]号中的是缺省值，”]”后的是输入值)

install_root: [/]

tempdir: [/root/postfix-2.6.5] /tmp/ postfix //其他的都是默认

config_directory: [/etc/postfix]

command_directory: [/usr/sbin]

daemon_directory: [/usr/libexec/postfix]

data_directory: [/var/lib/postfix]

html_directory: [no]

mail_owner: [postfix]

mailq_path: [/usr/bin/mailq]

manpage_directory: [/usr/local/man]

newaliases_path: [/usr/bin/newaliases]

queue_directory: [/var/spool/postfix]

readme_directory: [no]

sendmail_path: [/usr/sbin/sendmail]

setgid_group: [postdrop]

(4)生成别名二进制文件

# newaliases

(5)建立邮件存放目录

# mkdir -pv /var/mailbox

# chown -R vmail.vmail /var/mailbox

(6)建立配置文件

# cd /etc/postfix/

# mv main.cf main.cf.old

# vi main.cf

添加下面的内容

#=====================BASE=========================

myhostname = mail.xxt.cn

mydomain = xxt.cn

myorigin = $mydomain

mydestination =

mynetworks =  127.0.0.1

inet_interfaces = all

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:1000

virtual_gid_maps = static:1000

virtual_transport = maildrop:

maildrop_destination_recipient_limit = 1

maildrop_destination_concurrency_limit = 1

 

#====================QUOTA========================

message_size_limit = 52428800

smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/local_recipient, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
smtpd_sender_restrictions =
        permit_mynetworks,
        reject_sender_login_mismatch,

local_only = check_sender_access hash:/etc/postfix/local_sender, rejec

 

#==================clamd==========================

content_filter=amavisfeed:[127.0.0.1]:10024

 

(7)添加为支持虚拟域和虚拟用户所用到的配置文件，其实是直接在extman中复制过去

# tar zxvf extman-1.1.tar.gz

# cd extman-1.1

# cp docs/mysql_virtual_* /etc/postfix/

(8)启动postfix并加入到自启动

# /usr/sbin/postfix start

# echo "/usr/sbin/postfix start">>/etc/rc.local

 

8.安装maildrop

(1)安装和配置maildrop

# tar jxvf maildrop-2.5.0.tar.bz2

# cd maildrop-2.5.0

# ln -sv /usr/local/courier-authlib/bin/courierauthconfig /usr/bin/courierauthconfig

#yum install pcre-devel

#./configure  --prefix=/usr/local/maildrop --enable-sendmail=/usr/sbin/sendmail --enable-trusted-users="rootvmail"  --enable-syslog=1 --enable-maildirquota --enable-maildrop-uid=1000 --enable-maildrop-gid=1000  --with-trashquota--with-dirsync

# make && make install

# cp /usr/local/maildrop/bin/maildrop /usr/local/bin/

(2)查看一下安装结果

# maildrop -v

maildrop 2.5.0 Copyright 1998-2005 Double Precision, Inc.
GDBM/DB extensions enabled.
Courier Authentication Library extension enabled. //要保证这一行显示
Maildir quota extension are now always enabled.
This program is distributed under the terms of the GNU General Public
License. See COPYING for additional information.

(3)配置maildrop的日志文件

# vi /etc/maildroprc

logfile "/var/log/maildrop.log"

to "$HOME/Maildir"

VERBOSE="4"

 

或者

SHELL="/bin/sh" 

logfile "/var/log/maildrop.log" 

ACCOUNT=`echo "$LOGNAME" | cut -d@ -f1`  

USERDOMAIN=`echo "$LOGNAME" | cut -d@ -f2`  

############ Spam Filtering ###############  

 

if (/^X-Spam-Flag: *YES/)  

{  

     exception {  

           to "$HOME/Maildir/.Junk" 

       }  

}  

else 

{  

    exception {  

           to "$HOME/Maildir" 

      }  

}

下面的这个处理垃圾邮件，将垃圾邮件转移到垃圾邮件收件箱中

 

# touch /var/log/maildrop.log

# chown vmail.vmail /var/log/maildrop.log

(4)配置Postfix

# vi /etc/postfix/master.cf

去掉下面两行前面的#

maildrop  unix  -       n       n       -       -       pipe

flags=DRhu user=vmail argv=/usr/local/bin/maildrop -d ${recipient}

第二行改为

flags=DRhu user=vmail argv=/usr/local/bin/maildrop -w 90 -d ${user}@${nexthop} ${recipient} ${user} ${extension} {nexthop}

 

此处要注意argv=后边的maildrop要加上路径，否则会出现

temporary failure. Command output: pipe: fatal: pipe_command: execvp maildrop: No such file or directory

注意maildrop unix这行前边不能有空格,要不会出现以下错误提示

warning: connect to transport maildrop: No such file or directory

Oct 31 23:21:24 localhost postfix/error[2235]: BE0AE27DAF6: to=<[email protected]>,relay=none,delay=1443,delays=1443/0.24/0/0.02,dsn=4.3.0, status=deferred (mail transport unavailable)

注意flags=Drhu这一行前边有两个空格，要不会出现以下错（fatal: /etc/postfix/master.cf: line 100: bad transport type: user= vmail）。

 

 

注意前面要保留两个空格，不然会有问题

 

9.安装配置Extmail和Extman  

(1)安装和配置Extmail

# tar -zxvf extmail-1.2.tar.gz

# mkdir /var/www/extsuite

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

# cd /var/www/extsuite/extmail/

# cp webmail.cf.default webmail.cf

# vi webmail.cf

部分修改选项的说明：

 

SYS_USER_LANG = en_US

语言选项，可改作：

SYS_USER_LANG = zh_CN

 

SYS_MAILDIR_BASE = /home/domains

此处即为您在前文所设置的用户邮件的存放目录，可改作：

SYS_MAILDIR_BASE = /var/mailbox

 

SYS_MYSQL_USER = db_user

SYS_MYSQL_PASS = db_pass

以上两句句用来设置连接数据库服务器所使用用户名、密码和邮件服务器用到的数据库，这里修改为：

SYS_MYSQL_USER = extmail

SYS_MYSQL_PASS = extmail

 

 

SYS_MYSQL_HOST = localhost

指明数据库服务器主机名，这里默认即可

 

SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock

连接数据库的sock文件位置，这里修改为：

SYS_MYSQL_SOCKET = /tmp/mysql.sock

 

 

SYS_MYSQL_TABLE = mailbox

SYS_MYSQL_ATTR_USERNAME = username

SYS_MYSQL_ATTR_DOMAIN = domain

SYS_MYSQL_ATTR_PASSWD = password

以上用来指定验正用户登录里所用到的表，以及用户名、域名和用户密码分别对应的表中列的名称；这里默认即可

 

SYS_AUTHLIB_SOCKET = /var/spool/authdaemon/socket

此句用来指明authdaemo socket文件的位置，这里修改为：

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

 

修改 cgi执行文件属主为apache运行身份用户：

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

(2)安装配置Extman

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

#cd  /var/www/extsuite/extman

# mv webman.cf.default webman.cf

修改配置文件以符合本例的需要：

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

 

SYS_MAILDIR_BASE = /home/domains

此处即为您在前文所设置的用户邮件的存放目录，可改作：

SYS_MAILDIR_BASE = /var/mailbox

 

SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock

此处修改为：

SYS_MYSQL_SOCKET = /tmp/mysql.sock

(3)使用extman源码目录下docs目录中的extmail.sql和init.sql建立数据库：

# cd /var/www/extsuite/extman

# mysql -u root -p <docs/extmail.sql

# mysql -u root -p <docs/init.sql

(4)修改cgi目录的属主：

chown -R vmail.vmail /var/www/extsuite/extman/cgi

(5)extman和extmail需要Perl-Unix-Syslog、DBD-Mysql和perl-GD的支持

#perl -MCPAN -e  shell

然后一路回车后出现：

cpan>

然后我们输入：

cpan>install Unix::Syslog

cpan>install GD

cpan>install DBI

-----cpan>install DBD::mysql # DBD-Mysql目前最新的版本为DBD-mysql-4.006，但它和系统中的perl结合使用时会造成extmail无法正常使用，因此我们采用 3的版本

# tar -zxvf DBD-mysql-3.0008_1.tar.gz

# cd DBD-mysql-3.0008_1  

# perl Makefile.PL

# make

# make install

(6)建立extman和extmail的目录

# mkdir /tmp/extman

# chown -R vmail.vmail /tmp/extman/

# mkdir /tmp/extmail

# chown -R vmail.vmail /tmp/extmail/

(7)apache相关配置

# vi /usr/local/apache2/conf/httpd.conf

去掉这行前面的#号

Include conf/extra/httpd-vhosts.conf

 

# vi /usr/local/apache2/conf/extra/httpd-vhosts.conf

 

添加下面内容

<VirtualHost *:80>

ServerName mail.xxt.cn

DocumentRoot /var/www/extsuite/

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

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

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

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

SuexecUserGroup vmail vmail

</VirtualHost>

(8)重启一下apache服务器

#service httpd restart

到此，就全配置完了

/var/www/extsuite/extman/daemon --daemon   启动，否则到后台看不到系统信息。

但是系统控制是全是叉，应该还要启动一个服务，但是没有找到。。郁闷中

在浏览器中输入http://mail.xxt.cn/extman进入管理界面，默认内置账号是[email protected]，密码是 extmail*123*，添加一个域和用户

在http://mail.xxt.cn/extmail中登陆

(9)如果打开网页不显示验证码则需安装perl-GD

http://mirrors.xmu.edu.cn/CPAN/authors/id/L/LD/LDS/GD-2.45.tar.gz

tar zxvf GD-2.45.tar.gz

cd GD-2.45

perl Makefile.PL

make

make test

make install

 

 

10.安装图形化日志

(1)安装gd-2.0.35

# tar -jxvf gd-2.0.35.tar.bz2

# cd gd-2.0.35

# ./configure --with-png --with-freetype --with-jpeg --with-zlib --with-fontconfig

# make

如果GD报错:configure.ac:64: warning: macro `AM_ICONV' not found in library你就make clean一下，然后再make

如果你安装别的出现libtool没有找到，你就从/usr/bin/libtool cp 一个过来用就好了！

一般都会报上面的错，如果报错，安装完gettext后重新编译安装就可以了。

# make install

(2)安装Time-HiRes

# tar -zxvf Time-HiRes-1.9719.tar.gz

# cd Time-HiRes-1.9719

# perl Makefile.PL

# make

# make test

# make install

(3)安装File-Tail

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

# cd File-Tail-0.99.3

# perl Makefile.PL

# make

# make test

# make install

(4)安装rrdtool(用最新版的编译没通过)

#yum install tcl-devel

#yum install libpng

# yum install freetype

# yum install  libart_lgpl-devel

# tar -zxvf rrdtool-1.2.26.tar.gz

# cd rrdtool-1.2.26

# ./configure --prefix=/usr/local/rrdtool --enable-perl-site-install=/usr/lib/perl5/

# make

# make install

(5)复制mailgraph_ext到/usr/local，并启动之

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

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

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

# /usr/bin/perl -w /var/www/extsuite/extman/daemon/cmdserver -d

(6)添加到自动启动队列

echo "/usr/local/mailgraph_ext/mailgraph-init start" >>/etc/rc.local

echo "/usr/local/mailgraph_ext/qmonitor-init start" >>/etc/rc.local

echo “/usr/bin/perl -w /var/www/extsuite/extman/daemon/cmdserver -d” >>/etc/rc.local

 

安装完成

 

但是发现问题,从网页登陆extman后，进入到系统控制页面，发现只有mysql是启动状态，其它服务均显示已停止状态，在系统看，都是启动状态，用POP3也无法接收和发送邮件,问题待解决
