http://blog.51cto.com/zero01/2064693

主机名:mail.bk.sh

域名:bk.sh


1.准备工作

关闭selinux

[root@localhost ~]# setenforce 0
[root@localhost ~]# getenforce 
Permissive
[root@localhost ~]#

关闭firewalld

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# iptables -F
[root@localhost ~]# iptables -X
[root@localhost ~]# iptables -nvL

2.安装postfix

安装wget、mysql、epel

yum install -y wget
wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
rpm -ivh mysql-community-release-el7-5.noarch.rpm
wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -ivh epel-release-latest-7.noarch.rpm
yum install nginx vim gcc gcc-c++ openssl openssl-devel db4-devel ntpdate mysql mysql-devel mysql-server bzip2 php-mysql cyrus-sasl-md5 perl-GD perl-DBD-MySQL perl-GD perl-CPAN perl-CGI perl-CGI-Session cyrus-sasl-lib cyrus-sasl-plain cyrus-sasl cyrus-sasl-devel libtool-ltdl-devel telnet mail libicu-devel  -y

1.卸载系统自带的postfix,并删除postfix用户,重新指定uit gid创建新用户postfix,postdrop

yum remove postfix -y
userdel postfix
groupdel postdrop
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

2.下载源码包并解压编译

cd /usr/local/src/ 

wget http://cdn.postfix.johnriley.me/mirrors/postfix-release/official/postfix-3.2.5.tar.gz

tar -zxvf postfix-3.2.5.tar.gz

cd postfix-3.2.5.tar.gz make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/include/sasl -DUSE_TLS ' 'AUXLIBS=-L/usr/lib64/mysql -lmysqlclient -lz -lrt -lm -L/usr/lib64/sasl2 -lsasl2 -lssl -lcrypto' make && make install echo $?

更改第二项临时文件目录为:/tmp/extmail,其他一路回车

3.更改目录的属主和属组:

chown -R postfix:postdrop /var/spool/postfix
chown -R postfix:postdrop /var/lib/postfix/
chown root /var/spool/postfix
chown -R root /var/spool/postfix/pid

4.修改postfix的配置文件:

[root@localhost ~]# vim /etc/postfix/main.cf
myhostname = mail.bk.sh        //设置主机名
mydomain = bk.sh        //指定域名
myorigin = $mydomain        //指明发件人所在的域名
inet_interfaces =    all    //指定postfix系统监听的网络接口
mydestination = $myhostname, localhost.$mydomain, localhost,$mydomain        //指定postfix接收邮件时收件人的域名 [使用虚拟域需要禁用]
mynetworks_style = host        //指定信任网段类型
mynetworks = 192.168.77.1/24, 127.0.0.0/8        //指定信任的客户端
relay_domains = $mydestination        //指定允许中转邮件的域名
alias_maps = hash:/etc/aliases        //设置邮件的别名

5.在/etc/init.d/目录下创建脚本,控制postfix

[root@localhost /var/www/extsuite/extman]# vim /etc/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)
     start
     ;;
  stop)
     stop
     ;;
  restart)
     stop
     start
     ;;
  reload)
     reload
     ;;
  abort)
     abort
     ;;
  flush)
     flush
     ;;
  check)
     check
     ;;
  status)
       status master
     ;;
  condrestart)
     [ -f /var/lock/subsys/postfix ] && restart || :
     ;;
  *)
     echo $"Usage: $0 {start|stop|restart|reload|abort|flush|check|status|condrestart}"
     exit 1
esac

exit $?

6.为脚本添加权限并添加到开机启动项中

[root@localhost /var/www/extsuite/extman]# chmod +x /etc/init.d/postfix
[root@localhost /var/www/extsuite/extman]# chkconfig --add postfix
[root@localhost /var/www/extsuite/extman]# chkconfig postfix on
[root@localhost /var/www/extsuite/extman]# chown postfix.postfix -R /var/lib/postfix/
[root@localhost /var/www/extsuite/extman]# chown postfix.postfix /var/spool/ -R

3.安装dovecot

yum安装

[root@localhost ~]# yum install -y dovecot dovecot-mysql

配置dovecot:

[root@localhost ~]# cd /etc/dovecot/
[root@localhost dovecot]# vim dovecot.conf     //直接在配置文件最后添加即可
protocols = imap pop3
!include conf.d/*.conf
listen = *
base_dir = /var/run/dovecot/
[root@localhost dovecot]# cd conf.d/
[root@localhost conf.d]# vim 10-auth.conf
disable_plaintext_auth = no
[root@localhost conf.d]# vim 10-mail.conf
mail_location = maildir:~/Maildir
mail_location = maildir:/var/mailbox/%d/%n/Maildir
mail_privileged_group = mail
[root@localhost conf.d]# vim 10-ssl.conf
ssl = no
[root@localhost conf.d]# vim 10-logging.conf 
log_path = /var/log/dovecot.log
info_log_path = /var/log/dovecot.info
log_timestamp = "%Y-%m-%d %H:%M:%S "
[root@localhost conf.d]# cp auth-sql.conf.ext auth-sql.conf
[root@localhost conf.d]# vim auth-sql.conf
passdb {  
    driver = sql        

    # Path for SQL configuration file, see example-config/dovecot-sql.conf.ext  
    args = /etc/dovecot/dovecot-sql.conf.ext
}

userdb {  
    driver = sql  
    args = /etc/dovecot/dovecot-sql.conf.ext
}

编辑dovecot通过mysql认证的配置文件:

[root@localhost conf.d]# vim /etc/dovecot-mysql.conf
driver = mysql
connect = host=localhost dbname=extmail user=extmail password=extmail
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'

4.安装courier-authlib

下载解压并编译

[root@localhost ~]# cd /usr/local/src/
[root@localhost /usr/local/src]#  wget https://sourceforge.net/projects/courier/files/authlib/0.66.2/courier-authlib-0.66.2.tar.bz2
[root@localhost /usr/local/src]# tar -jxvf courier-authlib-0.66.2.tar.bz2

下载courier-unicode-1.2编译安装

[root@localhost ~]# wget https://sourceforge.net/projects/courier/files/courier-unicode/1.2/courier-unicode-1.2.tar.bz2
[root@localhost ~]# tar jxvf courier-unicode-1.2.tar.bz2 
[root@localhost ~]# cd courier-unicode-1.2
[root@localhost courier-unicode-1.2]# ./configure
[root@localhost courier-unicode-1.2]# make && make install

编译courier-anthlib

[root@localhost /usr/local/src]# cd courier-authlib-0.66.2
[root@localhost /usr/local/src/courier-authlib-0.66.2]# ./configure --prefix=/usr/local/courier-authlib     --sysconfdir=/etc     --without-authpam     --without-authshadow     --without-authvchkpw     --without-authpgsql     --with-authmysql     --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
[root@localhost /usr/local/src/courier-authlib-0.66.2]# make && make install

配置courier-authlib:

[root@localhost  courier-authlib-0.66.2]# chmod 755 /usr/local/courier-authlib/var/spool/authdaemon
[root@localhost  courier-authlib-0.66.2]# cp /etc/authdaemonrc.dist  /etc/authdaemonrc
[root@localhost  courier-authlib-0.66.2]# cp /etc/authmysqlrc.dist  /etc/authmysqlrc
[root@localhost  courier-authlib-0.66.2]# vim /etc/authdaemonrc      //配置文件里的验证方法比较多,我们这里只使用authmysql
authmodulelist="authmysql"
authmodulelistorig="authmysql"
[root@localhost  courier-authlib-0.66.2]# vim /etc/authmysqlrc     //直接添加到配置文件尾部,然后去上面将响应系统默认的注视掉,或者删除即可
MYSQL_SERVER            localhost
MYSQL_USERNAME          extmail
MYSQL_PASSWORD          extmail
MYSQL_SOCKET            /var/lib/mysql/mysql.sock
MYSQL_PORT               3306
MYSQL_DATABASE          extmail
MYSQL_USER_TABLE        mailbox
MYSQL_CRYPT_PWFIELD     password
DEFAULT_DOMAIN          test.com
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)

courier-authlib添加启动脚本及其他:

[root@localhost  courier-authlib-0.66.2]# cp courier-authlib.sysvinit /etc/init.d/courier-authlib
[root@localhost  courier-authlib-0.66.2]# chmod +x /etc/init.d/courier-authlib
[root@localhost  courier-authlib-0.66.2]# chkconfig --add courier-authlib
[root@localhost  courier-authlib-0.66.2]# chkconfig courier-authlib on
[root@localhost  courier-authlib-0.66.2]# echo "/usr/local/courier-authlib/lib/courier-authlib" >> /etc/ld.so.conf.d/courier-authlib.conf
[root@localhost  courier-authlib-0.66.1]# ldconfig
[root@localhost  courier-authlib-0.66.1]# service courier-authlib start
Starting Courier authentication services: authdaemond

smtp以及虚拟用户相关的设置:

[root@localhost ~]# vim /usr/lib64/sasl2/smtpd.conf    //文件不存在,要自己创建
pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket

[root@localhost ~]# vim /etc/postfix/main.cf
##postfix支持SMTP##
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = ''
smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination
broken_sasl_auth_clients=yes
smtpd_client_restrictions = permit_sasl_authenticated
smtpd_sasl_security_options = noanonymous
##postfix支持虚拟用户##
virtual_mailbox_base = /var/mailbox
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf   //这里的配置文件需在后面extman
里复制过来
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

5.安装extmail

下载extmail和extman:

[root@localhost ~]# cd /usr/local/src/
[root@localhost /usr/local/src]# wget http://7xivyw.com1.z0.glb.clouddn.com/extmail-1.2.tar.gz
[root@localhost /usr/local/src]# wget http://7xivyw.com1.z0.glb.clouddn.com/extman-1.1.tar.gz

创建站点目录并解压、重命名extmail包

[root@localhost /usr/local/src]# mkdir -p /var/www/extsuite
[root@localhost /usr/local/src]# tar -zxvf extmail-1.2.tar.gz -C /var/www/extsuite/
[root@localhost /usr/local/src]# mv /var/www/extsuite/extmail-1.2/ /var/www/extsuite/extmail

更改extmail的配置文件:

[root@localhost ~]# cd /var/www/extsuite/extmail
[root@localhost extmail]# cp webmail.cf.default webmail.cf
[root@localhost extmail]# vim webmail.cf
SYS_SESS_DIR = /tmp/extmail
SYS_UPLOAD_TMPDIR = /tmp/extmail/upload
SYS_USER_LANG = zh_CN
SYS_MIN_PASS_LEN = 8
SYS_MAILDIR_BASE = /var/mailbox
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
SYS_MYSQL_DB = extmail
SYS_MYSQL_HOST = localhost
SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock
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

建立临时文件目录与session目录,并更改权限:

[root@localhost extmail]# mkdir -p /tmp/extmail/upload
[root@localhost extmail]# chown -R postfix.postfix /tmp/extmail/

6.extman

到extmail的下载目录下,解压extman包:

[root@localhost ~]# cd /usr/local/src/
[root@localhost /usr/local/src]# tar -zxvf extman-1.1.tar.gz -C /var/www/extsuite/
[root@localhost /usr/local/src]# cd /var/www/extsuite/
[root@localhost /var/www/extsuite]# mv extman-1.1/ extman

拷贝extman的配置文件:

[root@localhost /var/www/extsuite]# cd extman/
[root@localhost /var/www/extsuite/extman]# cp webman.cf.default webman.cf

更改cgi目录的属主属组:

[root@localhost /var/www/extsuite/extman]# chown -R postfix.postfix /var/www/extsuite/extman/cgi/
[root@localhost /var/www/extsuite/extman]# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/

加载数据到数据库中,同时修改TYPE为ENGINE 数据库的文件是

[root@localhost /var/www/extsuite/extman]# vim docs/extmail.sql

数据导入后,登录mysql,创建一个mysql用户并授予权限:

[root@localhost /var/www/extsuite/extman]# mysql -uroot
mysql> GRANT ALL ON extmail.* to extmail@'%' identified by 'extmail';      //我这里是直接授予全部权限在任意的IP地址上了,实际情况根据需求而定
Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql>

复制之前的配置文件:

[root@localhost ~]# cd /var/www/extsuite/extman/docs/
[root@localhost /var/www/extsuite/extman/docs]# cp mysql_virtual_* /etc/postfix/

为extman创建临时目录:

[root@localhost /var/www/extsuite/extman/docs]# mkdir /tmp/extman
[root@localhost /var/www/extsuite/extman/docs]# chown -R postfix.postfix /tmp/extman/

启动postfix、dovecot、saslauthd服务,并查看进程是否正常:

[root@localhost /var/www/extsuite/extman]# service postfix start
Starting postfix (via systemctl):                          [  确定  ]

7.测试

测试虚拟用户:

[root@localhost courier-authlib-0.66.2]# /usr/local/courier-authlib/sbin/authtest -s login [email protected] extmail
Authentication succeeded.                //显示这个表示成功,测试时使用的是[email protected],因为我们导入的数据库init.sql里面自带了这个。
Authenticated: [email protected]  (uid 2525, gid 2525)
Home Directory: /var/mailbox/extmail.org/postmaster  //这里需要注意/var/mailbox这个目录现在我们还没有创建,后面web访问的时候如果没有会报错,所以提前创建。
                    Maildir: /var/mailbox/extmail.org/postmaster/Maildir/
                    Quota: (none)
            Encrypted Password: $1$phz1mRrj$3ok6BjeaoJYWDBsEPZb5C0
                Cleartext Password: extmail
                    Options: (none)
[root@localhost courier-authlib-0.66.2]# mkdir /var/mailbox
[root@localhost courier-authlib-0.66.2]# chown -R postfix.postfix /var/mailbox/

测试smtp发信:

8.启动nginx实现web访问

nginx本身并不能解析cgi,extmail自带了解析cgi的程序,但是有些地方需要修改下:

[root@localhost ~]# vim /var/www/extsuite/extmail/dispatch-init
SU_UID=postfix
SU_GID=postfix

启动dispatch-init:

root@localhost ~]# /var/www/extsuite/extmail/dispatch-init start
Starting extmail FCGI server...
[root@localhost ~]# /var/www/extsuite/extman/daemon/cmdserver -v -d 
loaded ok

添加nginx虚拟主机:

vim /etc/nginx/conf.d/extmail.conf

文件内容如下:

server {
   listen       8080;
   server_name  mail.everyoo.com;
   index index.html index.htm index.php index.cgi;
   root  /var/www/extsuite/extmail/html/;
   location /extmail/cgi/ {
             fastcgi_pass          127.0.0.1:8888;
             fastcgi_index         index.cgi;
             fastcgi_param  SCRIPT_FILENAME   /var/www/extsuite/extmail/cgi/$fastcgi_script_name;
             include               fcgi.conf;
        }
        location  /extmail/  {
             alias  /var/www/extsuite/extmail/html/;
        }
        location /extman/cgi/ {
             fastcgi_pass          127.0.0.1:8888;
             fastcgi_index         index.cgi;
             fastcgi_param  SCRIPT_FILENAME   /var/www/extsuite/extman/cgi/$fastcgi_script_name;
             include            fcgi.conf;
        }
        location /extman/ {
             alias  /var/www/extsuite/extman/html/;
        }
      access_log  /var/log/extmail_access.log;
}

创建fcgi.conf文件:

vim /etc/nginx/fcgi.conf

文件内容如下:

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx;
fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;
fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

安装Unix::Syslog:

[root@localhost ~]# cd /usr/local/src/
[root@localhost /usr/local/src]# wget http://www.cpan.org/authors/id/M/MH/MHARNISCH/Unix-Syslog-1.1.tar.gz
[root@localhost /usr/local/src]# tar zxvf Unix-Syslog-1.1.tar.gz 
[root@localhost /usr/local/src]# cd Unix-Syslog-1.1
[root@localhost /usr/local/src/Unix-Syslog-1.1]# perl Makefile.PL
[root@localhost /usr/local/src/Unix-Syslog-1.1]# make && make install

启动nginx,并检查进程和监听端口是否正常:

[root@localhost ~]# service nginx start
Redirecting to /bin/systemctl start  nginx.service
[root@localhost ~]# ps aux |grep nginx

然后到windows上访问你服务器IP的8080端口:

extman的登录账户为[email protected]密码为extmail*123*,首次使用需要先添加域,添加之后再修改域,改为可自由注册,再注册用户就可以登录发邮件了:
