闲来无事想着尝试使用postfix搭建一个邮箱服务器，我是边搭建边写这个笔记，搭建过程中遇到坑也会一并记录，使用的系统版本如下：
[[email protected] ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core) 本示例基于LNMP环境。
1. 准备工作
关闭selinux
[[email protected] ~]# setenforce 0 [[email protected] ~]# getenforce Permissive [[email protected] ~]# 关闭firewalld防火墙，并清空iptables规则：
[[email protected] ~]# systemctl stop firewalld [[email protected] ~]# iptables -F [[email protected] ~]# iptables -X [[email protected] ~]# iptables -nvL Chain INPUT (policy ACCEPT 38 packets, 7291 bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 12 packets, 1208 bytes) pkts bytes target prot opt in out source destination [[email protected] ~]# 由于CentOS7默认安装的是MariaDB，所以要添加MySQL的yum源，有些编译需要的devel包只有epel扩展源有，所以我们需要把epel源也一并添加。因为是通过wget命令从下载地址中下载，但是最小化安装的CentOS7不自带wget命令，还需要先安装这个命令：
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 2. 安装postfix
首先需要安装编译环境及其他所需要的包，免得一会编译过程中老报缺少包的错误，因为需要安装的包有点多，所以这个过程有点慢：
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 安装完以上所需的包后，开始编译安装postfix：
1、首先卸载系统自带的postfix，并删除postfix用户，重新指定uid、gid创建新用户postfix，postdrop，嫌一条条命令去执行有点麻烦就写成脚本文件去执行：
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（如果下载地址失效就到官网去找下载连接）：
cd /usr/local/src/ wget http://cdn.postfix.johnriley.me/mirrors/postfix-release/official/postfix-3.0.11.tar.gz tar -zxvf postfix-3.0.11.tar.gz cd postfix-3.0.11 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 $? 在make install环节的时候会有个交互式的界面，可以自定义一些目录，我这里只更改了第二项临时文件目录，其他的都选择了默认目录：
Please specify the prefix for installed file names. Specify this ONLY if you are building ready-to-install packages for distribution to OTHER machines. See PACKAGE_README for instructions. install_root: [/] Please specify a directory for scratch files while installing Postfix. You must have write permission in this directory. tempdir: [/usr/local/src/postfix-3.0.11] /tmp/extmail // 就只更改这一项为tmp目录，其他的全部默认 Please specify the final destination directory for installed Postfix configuration files. config_directory: [/etc/postfix] Please specify the final destination directory for installed Postfix administrative commands. This directory should be in the command search path of adminstrative users. command_directory: [/usr/sbin] Please specify the final destination directory for installed Postfix daemon programs. This directory should not be in the command search path of any users. daemon_directory: [/usr/libexec/postfix] Please specify the final destination directory for Postfix-writable data files such as caches or random numbers. This directory should not be shared with non-Postfix software. data_directory: [/var/lib/postfix] Please specify the final destination directory for the Postfix HTML files. Specify "no" if you do not want to install these files. html_directory: [no] Please specify the owner of the Postfix queue. Specify an account with numerical user ID and group ID values that are not used by any other accounts on the system. mail_owner: [postfix] Please specify the final destination pathname for the installed Postfix mailq command. This is the Sendmail-compatible mail queue listing command. mailq_path: [/usr/bin/mailq] Please specify the final destination directory for the Postfix on-line manual pages. You can no longer specify "no" here. manpage_directory: [/usr/local/man] Please specify the final destination pathname for the installed Postfix newaliases command. This is the Sendmail-compatible command to build alias databases for the Postfix local delivery agent. newaliases_path: [/usr/bin/newaliases] Please specify the final destination directory for Postfix queues. queue_directory: [/var/spool/postfix] Please specify the final destination directory for the Postfix README files. Specify "no" if you do not want to install these files. readme_directory: [no] Please specify the final destination pathname for the installed Postfix sendmail command. This is the Sendmail-compatible mail posting interface. sendmail_path: [/usr/sbin/sendmail] Please specify the group for mail submission and for queue management commands. Specify a group name with a numerical group ID that is not shared with other accounts, not even with the Postfix mail_owner account. You can no longer specify "no" here. setgid_group: [postdrop] Please specify the final destination directory for Postfix shared-library files. shlib_directory: [no] 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：
[[email protected] ~]# vim /etc/postfix/main.cf myhostname = mail.everyoo.com //设置主机名 mydomain = everyoo.com //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、然后需要在/etc/init.d/目录下提供一个脚本来管理postfix的启动与停止：
[roo[email protected] /var/www/extsuite/extman]# vim /etc/init.d/postfix 把下面的内容放在/etc/init.d/postfix里面：
#!/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 $? 为脚本添加执行权限，并将服务添加到开机启动项中：
[[email protected] /var/www/extsuite/extman]# chmod +x /etc/init.d/postfix [[email protected] /var/www/extsuite/extman]# chkconfig --add postfix [[email protected] /var/www/extsuite/extman]# chkconfig postfix on [[email protected] /var/www/extsuite/extman]# chown postfix.postfix -R /var/lib/postfix/ [[email protected] /var/www/extsuite/extman]# chown postfix.postfix /var/spool/ -R 3. 安装dovecot
yum安装：
[[email protected] ~]# yum install -y dovecot dovecot-mysql 配置dovecot：
[[email protected] ~]# cd /etc/dovecot/ [[email protected] 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/ [[email protected] dovecot]# cd conf.d/ [[email protected] conf.d]# vim 10-auth.conf disable_plaintext_auth = no [[email protected] conf.d]# vim 10-mail.conf mail_location = maildir:~/Maildir mail_location = maildir:/var/mailbox/%d/%n/Maildir mail_privileged_group = mail [[email protected] conf.d]# vim 10-ssl.conf ssl = no [[email protected] 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 " [[email protected] conf.d]# cp auth-sql.conf.ext auth-sql.conf [[email protected] 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：
[[email protected] 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：
[[email protected] ~]# cd /usr/local/src/ [[email protected] /usr/local/src]# wget https://sourceforge.net/projects/courier/files/authlib/0.66.2/courier-authlib-0.66.2.tar.bz2 [[email protected] /usr/local/src]# tar -jxvf courier-authlib-0.66.2.tar.bz2 [[email protected] /usr/local/src]# cd courier-authlib-0.66.2 [[email protected] /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 [[email protected] /usr/local/src/courier-authlib-0.66.2]# make && makeinstall 编译过程中发生了一个错误：
configure: error: The Courier Unicode Library 1.2 appears not to be installed. You may need to install a separate development subpackage, in addition to the main package 这是因为Courier Unicode Library没有安装，我们下载courier-unicode-1.2并编译安装：
[[email protected] ~]# wget https://sourceforge.net/projects/courier/files/courier-unicode/1.2/courier-unicode-1.2.tar.bz2 [[email protected] ~]# tar jxvf courier-unicode-1.2.tar.bz2 [[email protected] ~]# cd courier-unicode-1.2 [[email protected] courier-unicode-1.2]# ./configure [roo[email protected] courier-unicode-1.2]# make && make install 完成Courier Unicode Library的安装后，倒回去再次编译courier-authlib就没问题了
配置courier-authlib：
[[email protected] courier-authlib-0.66.2]# chmod 755 /usr/local/courier-authlib/var/spool/authdaemon [[email protected] courier-authlib-0.66.2]# cp /etc/authdaemonrc.dist /etc/authdaemonrc [[email protected] courier-authlib-0.66.2]# cp /etc/authmysqlrc.dist /etc/authmysqlrc [[email protected] 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" [[email protected] 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添加服务启动脚本及其他：
[[email protected] courier-authlib-0.66.2]# cp courier-authlib.sysvinit /etc/init.d/courier-authlib [[email protected] courier-authlib-0.66.2]# chmod +x /etc/init.d/courier-authlib [[email protected] courier-authlib-0.66.2]# chkconfig --add courier-authlib [[email protected] courier-authlib-0.66.2]# chkconfig courier-authlib on [[email protected] courier-authlib-0.66.2]# echo "/usr/local/courier-authlib/lib/courier-authlib" >> /etc/ld.so.conf.d/courier-authlib.conf [[email protected] courier-authlib-0.66.1]# ldconfig [[email protected] 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：
[[email protected] ~]# 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 [[email protected] ~]# 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：
[[email protected] ~]# cd /usr/local/src/ [[email protected] /usr/local/src]# wget http://7xivyw.com1.z0.glb.clouddn.com/extmail-1.2.tar.gz [[email protected] /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：
[[email protected] /usr/local/src]# mkdir -p /var/www/extsuite [[email protected] /usr/local/src]# tar -zxvf extmail-1.2.tar.gz -C /var/www/extsuite/ [[email protected] /usr/local/src]# mv /var/www/extsuite/extmail-1.2/ /var/www/extsuite/extmail 更改extmail的配置文件：
[[email protected] ~]# cd /var/www/extsuite/extmail [[email protected] extmail]# cp webmail.cf.default webmail.cf [[email protected] 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：
[[email protected] extmail]# mkdir -p /tmp/extmail/upload [r[email protected] extmail]# chown -R postfix.postfix /tmp/extmail/ 6. 安装extman
回到extman的下载目录下，解压extman包：
[[email protected] ~]# cd /usr/local/src/ [[email protected] /usr/local/src]# tar -zxvf extman-1.1.tar.gz -C /var/www/extsuite/ [[email protected] /usr/local/src]# cd /var/www/extsuite/ [[email protected] /var/www/extsuite]# mv extman-1.1/ extman 拷贝extman的配置文件：
[[email protected] /var/www/extsuite]# cd extman/ [[email protected] /var/www/extsuite/extman]# cp webman.cf.default webman.cf 更改cgi目录的属主属组：
[[email protected] /var/www/extsuite/extman]# chown -R postfix.postfix /var/www/extsuite/extman/cgi/ [[email protected] /var/www/extsuite/extman]# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/ 导入数据库：
由于数据库不能识别TYPE=MyISAM，所以这里直接导入会出错，需要先编辑extmail.sql数据库文件，将文件中的TYPE=MyISAM更改为ENGINE=MyISAM，共有五处修改：
[[email protected] /var/www/extsuite/extman]# vim docs/extmail.sql :% s/TYPE/ENGINE/g 我这里导入数据的时候发生了一个错误，提示找不到mysql.sock文件：
[[email protected] /var/www/extsuite/extman]# mysql -uroot < docs/extmail.sql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) [[email protected] /var/www/extsuite/extman]# ls /var/lib/mysql/mysql.sock ls: 无法访问/var/lib/mysql/mysql.sock: 没有那个文件或目录 解决：然后我去查看了一下/etc/my.cnf文件，发现没问题，socket参数指向的也是 /var/lib/mysql/mysql.sock 这个路径，于是我就重启了mysql服务，然后再尝试就没有报找不到mysql.sock文件的错误了，但是报了另一个错误：
[[email protected] /var/www/extsuite/extman]# mysql -uroot < docs/extmail.sql ERROR 1364 (HY000) at line 31: Field 'ssl_cipher' doesn't have a default value [[email protected] /var/www/extsuite/extman]# 这错误的意思是：字段 ‘ssl密码’ 没有默认值
于是又得去查看一下/etc/my.cnf文件，然后把sql_mode参数给注释掉：
接着重启mysql服务后，继续导入数据，这次就没问题了：
[[email protected] /var/www/extsuite/extman]# !service service mysqld restart Redirecting to /bin/systemctl restart mysqld.service [[email protected] /var/www/extsuite/extman]# mysql -uroot < docs/extmail.sql [[email protected] /var/www/extsuite/extman]# mysql -uroot < docs/init.sql 导入数据成功后再次修改/etc/my.cnf文件，把刚刚注释的那行给去掉注释，不去掉的话，mysql服务可能会出现不能启动的问题：
数据导入成功后，登录mysql，创建一个mysql数据库用户extmail并授予权限：
[[email protected] /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> 复制之前提到的配置文件：
[[email protected] ~]# cd /var/www/extsuite/extman/docs/ [[email protected] /var/www/extsuite/extman/docs]# cp mysql_virtual_* /etc/postfix/ 为extman创建临时目录：
[[email protected] /var/www/extsuite/extman/docs]# mkdir /tmp/extman [[email protected] /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：

[[email protected] 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) [[email protected] courier-authlib-0.66.2]# mkdir /var/mailbox [[email protected] 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：
[[email protected] ~]# vim /var/www/extsuite/extmail/dispatch-init SU_Ugrep nginx root 72338 0.0 0.1 122892 2296 ?
