一、安装前的准备工作:
1、安装所需的rpm包:
yum install -y httpd php php-mysql mysql mysql-server mysql-devel openssl-devel dovecot perl-DBD-MySQL tcl tcl-devel libart_lgpl libart_lgpl-devel
2、关闭sendmail,并将它的随系统自动启动功能关闭:
# service sendmail stop
# chkconfig sendmail off
//因为系统运行需要邮件服务的提供,所以最后在没有安装postfix之前,请不要#rpm -e sendmail;
3、安装以下开发所用到的rpm包组:
#yum groupinstall -y
"Development Libraries"
"Development Tools"
"Legacy Software Development"
"X Software Development"
4、启动mysql数据库,并给mysql的root用户设置密码:#service mysqld start
#chkconfig mysqld on
#mysqladmin -uroot password '123456'
#mysql -uroot -p
enter--> 123456
//简单测试
# service saslauthd start
//启用smtp认证
# chkconfig saslauthd on
二、安装配置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 /bin/false -M postdrop
# tar zxvf postfix-2.6.5.tar.gz
# cd postfix-2.6.5
# 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'
//编译时修改的一些参数 // 如果没有特殊需要,只作为邮件传输MTA应用,不必要添加此类参数;
# make
# make install
//如果编译出错,检查出错情况,一般是有包忘了装,要不是参数路径错误;

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,省略的表示采用默认值)(可全部采用默认值)
install_root: [/] /
tempdir: [/root/postfix-2.6.5]
config_directory: [/etc/postfix]
command_directory: [/usr/sbin]
daemon_directory: [/usr/libexec/postfix]
data_directory: [/var/lib/postfix]

sendmail_path: [/usr/sbin/sendmail]
setgid_group: [postdrop]
(注意)生成别名二进制文件,这个步骤如果忽略,会造成postfix效率极低:
# newaliases
2.进行一些基本配置,测试启动postfix并进行发信
#vim /etc/postfix/main.cf
修改以下几项为您需要的配置
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
说明:
myorigin参数用来指明发件人所在的域名;
mydestination参数指定postfix接收邮件时收件人的域名,即您的postfix系统要接收到哪个域名的邮件;
myhostname 参数指定运行postfix邮件系统的主机的主机名,默认情况下,其值被设定为本地机器名;
mydomain参数指定您的域名,默认情况下,postfix将myhostname的第一部分删除而作为mydomain的值;
mynetworks
参数指定你所在的网络的网络地址,postfix系统根据其值来区别用户是远程的还是本地的,如果是本地网络用户则允许其访问;
inet_interfaces 参数指定postfix系统监听的网络接口;
启动postfix
#/usr/sbin/postfix start

使用以下命令验正postfix是否支持cyrus风格的sasl认证,如果您的输出为以下结果,则是支持的:
# /usr/local/postfix/sbin/postconf -a
cyrus
dovecot
添加以下内容:
############################CYRUS-SASL############################
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions=permit_mynetworks, //下一行与此行为同一行,下一行开头,空一格
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_sasl_application_name = smtpd
smtpd_banner = Welcome to our $myhostname ESMTP,Warning: Version not Available!
2011年4月12日更正:
smtpdsmtpd_sasl_application_name = smtpd
正确:
smtpd_sasl_application_name = smtpd
#vim /usr/lib/sasl2/smtpd.conf
添加如下内容:
pwcheck_method: saslauthd
mech_list: PLAIN LOGIN
让postfix重新加载配置文件
#/usr/sbin/postfix reload
postfix/postfix-script: refreshing the Postfix mail
system
# telnet localhost 25

四、安装Courier authentication library
# tar jxvf courier-authlib-0.62.4.tar.bz2
# cd courier-authlib-0.62.4
#./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 CFLAGS="-march=i686 -O2 -fexpensive-optimizations" CXXFLAGS="-march=i686 -O2 -fexpensive-optimizations"
# 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#vim /etc/authdaemonrc 文件
authmodulelist="authmysql"
authmodulelistorig="authmysql"
daemons=10
编辑#vim /etc/authmysqlrc
为以下内容,其中2525,2525 为postfix 用户的UID和GID。
MYSQL_SERVER localhost
MYSQL_PORT 3306 (指定你的mysql监听的端口,这里使用默认的3306)
MYSQL_USERNAME extmail (这时为后文要用的数据库的所有者的用户名)
MYSQL_PASSWORD extmail (密码)
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)
!!!保证此文件的内容不能有错,否则不能启用postfix与mysql的连接;
# 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
# ldconfig -v
# service courier-authlib start (启动服务)
Starting Courier authentication services: authdaemond (可信的,
可靠的)
#mkdir –pv /var/mailbox
#chown –R postfix /var/mailbox
接下来重新配置SMTP 认证,编辑 /usr/local/lib/sasl2/smtpd.conf ,确保其为以下内容:
pwcheck_method: authdaemond
log_level: 3
mech_list:PLAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket
1、编辑 #vim/etc/postfix/main.cf,添加如下内容:
########################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, try again later.
virtual_overquota_bounce = yes
2011年4月12日更正:virtualvirtual_transport = virtual
正确:virtual_transport = virtual
2、使用extman源码目录下docs目录中的extmail.sql和init.sql建立数据库:
# 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、授予用户extmail访问extmail数据库的权限
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'; 密码
说明:启用虚拟域以后,需要取消中心域,即注释掉myhostname, mydestination, mydomain,
myorigin几个指令;
当然,你也可以把mydestionation的值改为你自己需要的。
#vim /etc/postfix/main.cf
注释掉myhostname, mydestination, mydomain, myorigin
六、配置dovecot
# vim /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
说明:"[]"内为同一行使用时去掉"[]",下同 2010年11月29日更新
password_query = [SELECT username AS user,password AS password FROM mailbox WHERE username = '%u']
# service dovecot start
#netstat -tnlp | grep :110
tcp 0 0 :::110 :::* LISTEN 21456/dovecot
# chkconfig dovecot on
1、安装
# 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、修改主配置文件
#vim /var/www/extsuite/extmail/webmail.cf
部分修改选项的说明:
SYS_MESSAGE_SIZE_LIMIT = 5242880
用户可以发送的最大邮件
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_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
3、apache相关配置
由于extmail要进行本地邮件的投递操作,故必须将运行apache服务器用户的身份修改为您的邮件投递代理的用户;
本例中打开了apache服务器的suexec功能,故使用以下方法来实现虚拟主机运行身份的指定。
此例中的MDA为postfix自带,因此将指定为postfix用户:
#vim /etc/httpd/conf/httpd.conf
<VirtualHost *:80>
ServerName mail.test.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执行文件属主为apache运行身份用户:
# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/
如果您没有打开apache服务器的suexec功能,也可以使用以下方法解决:
# vi /etc/httpd/httpd.conf
User postfix
Group postfix
<VirtualHost *:80>
ServerName mail.test.com
DocumentRoot /var/www/extsuite/extmail/html/
ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi
Alias /extmail /var/www/extsuite/extmail/html
</VirtualHost>
4、依赖关系的解决extmail将会用到perl的Unix::syslogd功能,您可以去http://search.cpan.org搜索下载原码包进行安装。
# tar zxvf Unix-Syslog-0.100.tar.gz
# cd Unix-Syslog-0.100
# perl Makefile.PL
# make
# make install
5、启动apache服务
# service httpd start
# chkconfig httpd on
八、安装Extman-1.1
1、安装及基本配置
# 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
修改cgi目录的属主:
# chown -R postfix.postfix /var/www/extsuite/extman/cgi/
在apache的主配置文件中Extmail的虚拟主机部分,添加如下两行:
#vim /etc/httpd/conf/httpd.conf
ScriptAlias /extman/cgi /var/www/extsuite/extman/cgi
Alias /extman /var/www/extsuite/extman/html
创建其运行时所需的临时目录,并修改其相应的权限:
#mkdir -pv /tmp/extman
#chown postfix.postfix /tmp/extman
修改 vim /var/www/extsuite/extman/webman.cf
SYS_CAPTCHA_ON = 1
为
SYS_CAPTCHA_ON = 0
好了,到此为止,重新启动apache服务器后,您的Webmail和Extman已经可以使用了,可以在浏览器中输入指定的虚拟主机的名称进行访问,如下:
总结:由于笔者今天事太多了,又是第一次采用代码方式书写的blog,其中可能有疏忽错误之处,敬请指教;
在以后可能还会续写用图型化来监控extmail的使用流量;所用包均在官方网站能够downloads;
