postfix+dovecot+extmail

邮件服务器postfix+dovecot+extmail(需要lamp环境)

修改主机IP和主机名以及DNS服务器

配置DNS服务

shell>vim /var/named/chroot/etc/named.conf #将参数localhost修改为any

shell>vim /var/named/chroot/etc/named.rfc1912.zones #添加邮件服务器的管理域

shell>vim /var/named/chroot/var/named/gz.com.zone #在域中添加资源记录

安装需要的rpm软件包

yum install mysql mysql-devel openssl-devel dovecot perl-DBD-MySQL tcl tcl-devel libart_lgpl libart_lgpl-devel libtool-ltdl libtool-ltdl-devel expect

建立邮件服务器的账号

[root@mail ~]# groupadd -g 2013 postfix

[root@mail ~]# groupadd -g 2014 postdrop

[root@mail ~]# useradd -g postfix -u 2013 -s /sbin/nologin -M postfix

安装postfix

shell>tar -zxvf postfix-2.8.2.tar.gz -C /usr/local/src

shell>cd /usr/local/src/postfix-2.8.2

shell>make makefiles'CCARGS=-DHAS_MYSQL

-I /usr/include/mysql/ -DUSE_SASL_AUTH-DUSE_TLS-DUSE_CYRUS_SASL

-I /usr/include/sasl'

'AUXLIBS=-L/usr/lib/mysql -lmysqlclient -lz -lm -L/usr/lib/sasl2 -lsasl2 -lssl -lcrypto '

Shell>make && make install

install_root: [/]

tempdir: [/usr/local/src/postfix-2.8.2] /tmp （自选）

config_directory: [/etc/postfix]

command_directory: [/usr/sbin]

daemon_directory: [/usr/libexec/postfix]

data_directory: [/var/lib/postfix]

html_directory: [no] /usr/local/apache/postfix（自选）

提取postfix-rpm中的脚本

shell> mkdir /script

shell>cp /mnt/cdrom/Server/postfix-2.3.3-2.1.el5_2.i386.rpm /script

shell>cd /script/

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

shell>cp -p /script/etc/rc.d/init.d/postfix /etc/init.d/

shell>ln -s /usr/local/postfix/include /usr/include/postfix

shell>vim /etc/profile

shell>vim /etc/ld.so.conf.d/postfix.conf

shell>service postfix start

shell>chkconfig postfix on

shell>vim /etc/postfix/main.cf

75 myhostname = mail.gz.com

83 mydomain = gz.com

113 inet_interfaces = all

这时如果没有问题就可以使用telnet 127.0.0.1 25 测试发信再用mail命令接受信件

postfix验证

Postfix结合mysql验证需要一个smtpd.conf的文件

shell> cd /usr/lib/sasl2

shell> cp -p Sendmail.conf smtpd.conf

shell> vim smtpd.conf

pwcheck_method:authdaemond

log_level:3

mech_list: PLAIN LOGIN

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

shell> service saslauthd start

shell> chkconfig saslauthd on

安装courier-authlib结合mysql数据库实现验证

shell> tar -jxvf courier-authlib-0.63.0.tar.bz2 -C /usr/local/src/

shell> cd /usr/local/src/courier-authlib-0.63.0/

./configure \

shell> make && make install

shell> chmod 755 /usr/local/courier-authlib/var/spool/authdaemon/

shell> cp -p /etc/authdaemonrc.dist /etc/authdaemonrc

shell> cp -p /etc/authmysqlrc.dist /etc/authmysqlrc

shell> vim /etc/authdaemonrc

shell>cp -p/usr/local/src/courier-authlib-0.63.0/courier-authlib.sysvinit /etc/init.d/courier-authlib

shell> chmod a+x /etc/init.d/courier-authlib

shell>vim /etc/postfix/main.cf (在最后面添加以下内容)

shell> service courier-authlib start

dovecot验证

shell>vim /etc/dovecot.conf

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

869 passdb sql {

871 args = /etc/dovecot-mysql.conf

872 }

932 args = /etc/dovecot-mysql.conf

933 }

shell>vim /etc/dovecot-mysql.conf (这个文件没有需要自己创建)

1 driver = mysql

2 connect = host=/tmp/mysql.sock

3 default_pass_scheme = CRYPT

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

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

建设站点 导入数据库 配置虚拟域

建设站点

shell> mkdir -pv /var/mailbox

mkdir: created directory `/var/mailbox'

shell> chown -R postfix /var/mailbox

shell>mkdir -pv /var/www/extsuite

shell>tar zxvf extmail-1.2.tar.gz -C /var/www/extsuite/

shell>tar zxvf extman-1.1.tar.gz -C /var/www/extsuite/

shell>cd /var/www/extsuite/

shell>mv extmail-1.2 extmail

shell>mv extman-1.1 extman

修改extmail和extman目录下cgi的所有者和所有组

修改相关文件的所有者和所属组，并修改webmail.cf配置文件和wenman.cf

shell>cd /var/www/extsuite/extmail/

shell>chown -R postfix:postfix cgi/

shell>cp -p webmail.cf.default webmail.cf

shell>vim webmail.cf

SYS_USER_LANG = zh_CN

SYS_MAILDIR_BASE = /var/mailbox

SYS_MYSQL_USER = extmail

SYS_MYSQL_PASS = extmail

SYS_MYSQL_HOST = localhost

SYS_MYSQL_TABLE = mailbox

SYS_MYSQL_ATTR_USERNAME = username

SYS_MYSQL_ATTR_DOMAIN = domain

SYS_MYSQL_ATTR_PASSWD = password

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

shell>cd /var/www/extsuite/extman/

shell>chown -R postfix:postfix cgi/

shell>cp webmail.cf.default webmail.cf

shell>cp webman.cf.default webman.cf

SYS_MAILDIR_BASE = /var/mailbox

SYS_CAPTCHA_ON = 0

修改httpd的配置文件

shell>vim /etc/httpd/httpd.conf

LoadModule cgid_module modules/mod_cgid.so

</Virtualhost>

导入数据库并初始化和授权

shell>cd /var/www/extsuite/extman/docs/

shell>mysql -uroot -p <extmail.sql

使用rpm包安装mysql-server不需要修改extmail.sql,是源码安装的mysqlserver需要修改此文件

需要修改四项

1：添加字段

INSERT INTO user (Host, User,Password,ssl_cipher,x509_issuer,x509_subject) VALUES

('localhost','extmail',password('extmail'),'Y','Y','Y');

INSERT INTO user (Host, User, Password,ssl_cipher,x509_issuer,x509_subject) VALUES

('localhost','webman',password('webman'),'Y','Y','Y');

2：将指定的数据引擎删除 TYPE=MyISAM COMMENT='ExtMail - Virtual Aliases',不要把最后的分号也删了

3：将文本类型的默认为空删除

例如 question text NOT NULL default '',改为question text NOT NULL default '',

4：将 can_signup tinyint(1) NOT NULL default '0', 改为can_signup varchar(22) NOT NULL default '0',

shell>mysql -uroot -p <init.sql

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

mysql> GRANT all privileges on extmail.* TO [email protected] IDENTIFIED BY 'extmail';

mysql>FLUSH PRIVILEGES; 让设置的内容生效

使邮件服务器支持虚拟域

shell>cp -p /var/www/extsuite/docs/mysql* /etc/postfix

shell>vim /etc/postfix/main.cf
