Ubuntu之邮件服务器(Postfix, Dovecot, MySql)
前提
- 系统为 Ubuntu , 版本为14.04, 其余版本问题应该不大
系统 hostname 为 zjc - 详见设置linux主机名 ----- 此步非必须html
$ sudo sunode# echo zjc > /etc/hostnamemysql# exitlinux
系统IP地址为
10.1.6.49sql一些地址映射 要加入/etc/hosts文件或者DNS数据库
$ sudo apt-get install vimubuntu$ sudo vim /etc/hosts#天然，也能够用其余文本编辑器vim#新添加的项 10.1.6.49 zjc zjc.com vzjc.com mail.vzjc.com
修改完毕后最好重启一下机器centos
$ sudo shutdown -r now
安装依赖包
$ sudo apt-get install openssl telnet libsasl2-2 libsasl2-modules libsasl2-modules-sql sasl2-bin libpam-mysql
安装mysql
$ sudo apt-get install mysql-client mysql-server
首次安装后会提示输入mysql密码，输入确认并记住，之后还须要用到bash
设置MySQL数据库
其中的
mail_admin和password-for-mail_admin为生成的数据库mail的用户名和密码，能够修改为本身的，可是一旦修改，后文中出现的地方都要修改。
$ mysql -u root -p
Enter password: input your password
mysql> CREATE DATABASE mail;
mysql> USE mail;
mysql> GRANT SELECT, INSERT, UPDATE, DELETE ON mail. TO 'mail_admin'@'localhost' IDENTIFIED BY 'password-for-mail_admin'; mysql> GRANT SELECT, INSERT, UPDATE, DELETE ON mail. TO 'mail_admin'@'127.0.0.1' IDENTIFIED BY 'password-for-mail_admin';
mysql> FLUSH PRIVILEGES;
mysql> CREATE TABLE domains (domain varchar(50) NOT NULL, PRIMARY KEY (domain) );
mysql> CREATE TABLE forwardings (source varchar(80) NOT NULL, destination TEXT NOT NULL, PRIMARY KEY (source) );
mysql> CREATE TABLE users (email varchar(80) NOT NULL, password varchar(20) NOT NULL, PRIMARY KEY (email) );
mysql> CREATE TABLE transport ( domain varchar(128) NOT NULL default '', transport varchar(128) NOT NULL default '', UNIQUE KEY domain (domain) );
mysql> quit
安装Postfit及相关
$ sudo apt-get install postfix postfix-mysql postfix-doc mailutils
若是postfit弹出设置界面，那么
General type of mail configuration 选择 Internet Site
System Mail Name 选择 vzjc.com
配置Postfit
虚拟domain配置文件
$ sudo vim /etc/postfix/mysql-virtual_domains.cf
user = mail_adminpassword = password-for-mail_admindbname = mailquery = SELECT domain AS virtual FROM domains WHERE domain='%s'hosts = 127.0.0.1
虚拟forwarding配置文件
$ sudo vim /etc/postfix/mysql-virtual_forwardings.cf
user = mail_adminpassword = password-for-mail_admindbname = mailquery = SELECT destination FROM forwardings WHERE source='%s'hosts = 127.0.0.1
虚拟mailbox配置文件
$ sudo vim /etc/postfix/mysql-virtual_mailboxes.cf
user = mail_adminpassword = password-for-mail_admindbname = mailquery = SELECT CONCAT(SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'@',1),'/') FROM users WHERE email='%s'hosts = 127.0.0.1
虚拟email2email配置文件
$ sudo vim /etc/postfix/mysql-virtual_email2email.cf
user = mail_adminpassword = password-for-mail_admindbname = mailquery = SELECT email FROM users WHERE email='%s'hosts = 127.0.0.1
设置权限
$ sudo chmod o= /etc/postfix/mysql-virtual_*.cf$ sudo chgrp postfix /etc/postfix/mysql-virtual_*.cf
创建用户
$ sudo groupadd -g 5000 vmail$ sudo useradd -c 'VMail' -g vmail -u 5000 vmail -d /home/vmail -m
使用postconf配置
此处有个须要注意的地方mynetworks应该包含本机的全部IP地址,例如我这里只有一个10.1.6.197,否则会致使发给本身的域的邮件接收不到。若是仍是接收不到，那么重启机器看看
postconf -e 'myhostname = vzjc.com'postconf -e 'mydestination = vzjc.com, localhost, localhost.localdomain'postconf -e 'mynetworks = 127.0.0.0/8, 10.1.6.197'postconf -e 'message_size_limit = 30720000'postconf -e 'virtual_alias_domains ='postconf -e 'virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf, mysql:/etc/postfix/mysql-virtual_email2email.cf'postconf -e 'virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf'postconf -e 'virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf'postconf -e 'virtual_mailbox_base = /home/vmail'postconf -e 'virtual_uid_maps = static:5000'postconf -e 'virtual_gid_maps = static:5000'postconf -e 'smtpd_sasl_auth_enable = yes'postconf -e 'broken_sasl_auth_clients = yes'postconf -e 'smtpd_sasl_authenticated_header = yes'postconf -e 'smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination'postconf -e 'smtpd_use_tls = yes'postconf -e 'smtpd_tls_cert_file = /etc/postfix/smtpd.cert'postconf -e 'smtpd_tls_key_file = /etc/postfix/smtpd.key'postconf -e 'proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $virtual_mailbox_limit_maps'postconf -e 'virtual_transport = dovecot'postconf -e 'local_transport = dovecot'
为postfix建立证书
$ cd /etc/postfix$ sudo openssl req -new -outform PEM -out smtpd.cert -newkey rsa:2048 -nodes -keyout smtpd.key -keyform PEM -days 3650 -x509
更改证书权限
$ sudo chmod o= /etc/postfix/smtpd.key
配置saslauthd
$ sudo mkdir -p /var/spool/postfix/var/run/saslauthd$ sudo cp -a /etc/default/saslauthd /etc/default/saslauthd.bak
$ sudo vim /etc/default/saslauthd
START=yesDESC="SASL Authentication Daemon"NAME="saslauthd"MECHANISMS="pam"MECH_OPTIONS=""THREADS=5OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd -r"

设置权限
$ sudo chmod o= /etc/pam.d/smtp$ sudo chmod o= /etc/postfix/sasl/smtpd.conf
重启服务
$ sudo adduser postfix sasl$ sudo service postfix restart$ sudo service saslauthd restart
安装dovecot及相关
安装dovecot
$ sudo apt-get install dovecot-common dovecot-imapd dovecot-pop3d dovecot-mysql
弹出的选项中选择生成根证书，而且生成的证书dovecot.pem应该在/etc/dovecot/下面，key在/etc/dovecot/private下面。请确认这一点
hostname 填写 vzjc.com
配置dovecot
$ sudo vim /etc/postfix/master.cf
取消submission配置的注释：
submission inet n - - - - smtpd -o syslog_name=postfix/submission -o smtpd_tls_security_level=encrypt -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=$mua_client_restrictions -o milter_macro_daemon_name=ORIGINATING
文件末尾增长
dovecot unix - n n - - pipe
flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient}
$ sudo cp -a /etc/dovecot/dovecot.conf /etc/dovecot/dovecot.conf.bak
清空文件/etc/dovecot/dovecot.conf，加入以下
$ sudo vim /etc/dovecot/dovecot.conf
: 1,$d
ssl_cert, ssl_key指向的证书和私钥必须存在
log_timestamp = "%Y-%m-%d %H:%M:%S "mail_location = maildir:/home/vmail/%d/%n/Maildirnamespace { inbox = yes location = prefix = INBOX. separator = . type = private}passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql}protocols = imap pop3disable_plaintext_auth = noauth_mechanisms = plain loginservice auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } user = root}ssl = requiredssl_cert = </etc/dovecot/dovecot.pemssl_key = </etc/dovecot/private/dovecot.pemuserdb { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes driver = static}protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = /home/vmail/dovecot-deliver.log postmaster_address = postmaster@zjc.com}protocol pop3 { pop3_uidl_format = %08Xu%08Xv}
dovecot-sql.conf
$ sudo cp -a /etc/dovecot/dovecot-sql.conf /etc/dovecot/dovecot-sql.conf.bak
$ sudo vim /etc/dovecot/dovecot-sql.conf
driver = mysqlconnect = host=127.0.0.1 dbname=mail user=mail_admin password=password-for-mail_admindefault_pass_scheme = CRYPTpassword_query = SELECT email as user, password FROM users WHERE email='%u';
$ sudo service dovecot restart
$ sudo chgrp vmail /etc/dovecot/dovecot.conf
$ sudo chmod g+r /etc/dovecot/dovecot.conf
设置mail aliases - 详见aliases配置文件 -- 这个是给sendmail程序用的吧，反正我是没看出来为啥要配置它
$ sudo vim /etc/aliases
postmaster: root
root:admin@vzjc.com
测试
添加邮件帐户
$ mysql -u root -p
Enter password: input your password
mysql> USE mail;
mysql> INSERT INTO domains (domain) VALUES ('vzjc.com');
mysql> INSERT INTO users (email, password) VALUES ('test1@vzjc.com', ENCRYPT('password-for-test1'));
mysql> INSERT INTO users (email, password) VALUES ('test2@vzjc.com', ENCRYPT('password-for-test2'));
mysql> INSERT INTO users (email, password) VALUES ('admin@vzjc.com', ENCRYPT('111111'));
mysql> quit
### 重启机器
> 作完上面操做后若是用
telnet vzjc.com 587，则显示不能链接，机器重启后就能够了 -- 缘由待查$ sudo shutdown -r now### 用telnet测试

用客户端测试
能够用ubuntu的thunderbird或者其余系统的outlook，foxmail等客户端测试，若是是其余机器上，注意一系列端口号必定要被服务器开放
