postfix+dovecot+extmail打造開源郵件系統

postfix+dovecot+courier-authlib+mariadb+extmail打造開源郵件系統

 

企業中處於郵件帳戶的數量衆多，使用商業版本的郵件系統價格高昂，再加上使用商業版本的郵件系統，郵件內容保護也會帶必定的麻煩，因此仍是有很多企業選擇了開源郵件系統，畢竟本身的郵件數據存儲在本身的服務器上仍是比較放心的，那麼就給你們分享一下如何使用阿里雲的ECS搭建本身的純開源方案的郵件系統。

 

環境展現

操做系統：CentOS7.2
yum源：阿里base源+阿里epel源
postfix：3.2.4 編譯安裝
dovecot：2.2.10-8 yum安裝
courier-unicode：2.0
courier-authlib：0.68.0
extmail：1.2
extman：1.1
perl-Unix-Syslog：1.1-17 yum安裝
Time-HiRes：1.9746 編譯安裝
File-Tail：1.3 編譯安裝
nginx：1.12.2-1 yum安裝
阿里雲ECS默認不是開放25號端口的，因此須要提交工單申請開通25號端口
 

系統自帶的postfix用戶ID是89，使用起來有些問題 因此這裏咱們直接卸載，後面再編譯安裝

yum remove -y postfix
userdel -r postfix
groupdel postdrop
rm -rf /var/spool/postfix/
rm -rf /var/lib/postfix/
 
最小化安裝系統上須要安裝的一些基礎包
yum install -y vim lrzsz wget dos2unix psmisc tcpdump net-tools iftop
yum install -y bash-completion && source /etc/profile.d/bash_completion.sh
yum install -y tree lsof screen telnet
yum install -y gcc gcc-c++ perl-CPAN perl-GD perl-DB_File perl-DBD-MySQL perl-ExtUtils-MakeMaker rrdtool-perl libicu-devel perl-Crypt-PasswdMD5 perl-CGI perl-CGI-Session gdbm-devel libtool-ltdl-devel bzip2
 
安裝及配置虛擬域須要用到的數據庫
yum install -y mariadb-server mariadb-devel
mkdir /data/mysql
chown mysql:mysql /data/mysql
vim /etc/my.cnf
grep -v ^# /etc/my.cnf | tr -s [[:space:]]
[mysqld]
datadir=/data/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
skip_name_resolve
innodb_file_per_table
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
!includedir /etc/my.cnf.d
 
編譯安裝postfix
mkdir /data/package
cd /data/package
wget http://cdn.postfix.johnriley.me/mirrors/postfix-release/official/postfix-3.2.4.tar.gz
tar xf postfix-3.2.4.tar.gz
cd postfix-3.2.4/
useradd -u 2525 -M -s /sbin/nologin postfix
useradd -u 2526 -M -s /sbin/nologin postdrop
yum install -y cyrus-sasl cyrus-sasl-devel cyrus-sasl-md5 cyrus-sasl-plain
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 -j4
make install
 
配置postfix

cp /etc/postfix/main.cf{,.bak}
vim /etc/postfix/main.cf
grep -v ^# /etc/postfix/main.cf | tr -s [[:space:]]

data_directory = /var/lib/postfix
mail_owner = postfix
inet_interfaces = all
unknown_local_recipient_reject_code = 550
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
home_mailbox = Maildir/
mail_spool_directory = /var/spool/mail
debug_peer_level = 2
debugger_command =
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
ddd $daemon_directory/$process_name $process_id & sleep 5
sendmail_path = /usr/sbin/sendmail

virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
 
因修改過postfix工做目錄，須要建立並受權其屬主爲postfix
mkdir /data/mailbox
chown postfix /data/mailbox
 
yum安裝cyrus認證框架
yum install -y cyrus-sasl cyrus-sasl-devel cyrus-sasl-md5 cyrus-sasl-plain
 
安裝及配置dovecot
yum install -y dovecot.x86_64 dovecot-mysql.x86_64
cp /etc/dovecot/dovecot.conf{,.bak}
vim /etc/dovecot/dovecot.conf
grep -v ^[[:space:]]# /etc/dovecot/dovecot.conf | tr -s [[:space:]]
protocols = imap pop3
listen =
base_dir = /data/dovecot/
!include conf.d/.conf
!include_try local.conf
 
mv /var/run/dovecot/ /data/
cp /etc/dovecot/conf.d/10-auth.conf{,.bak}
vim /etc/dovecot/conf.d/10-auth.conf
grep -v ^[[:space:]]# /etc/dovecot/conf.d/10-auth.conf | tr -s [[:space:]]

!include auth-sql.conf.ext
 
cp /etc/dovecot/conf.d/10-mail.conf{,.bak}
vim /etc/dovecot/conf.d/10-mail.conf
grep -v ^[[:space:]]# /etc/dovecot/conf.d/10-mail.conf | tr -s [[:space:]]
 
mail_location = maildir:/data/mailbox/%d/%n/Maildir
namespace inbox {
inbox = yes
}
mbox_write_locks = fcntl
 
cp /etc/dovecot/conf.d/10-ssl.conf{,.bak}
vim /etc/dovecot/conf.d/10-ssl.conf
 
grep -v ^[[:space:]]# /etc/dovecot/conf.d/10-ssl.conf | tr -s [[:space:]]
ssl = no
 
手動添加dovecot鏈接mysql的認證配置文件
vim /etc/dovecot/dovecot-sql.conf.ext
cat /etc/dovecot/dovecot-sql.conf.ext
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'
 
編譯安裝courier-unicode和courier-authlib
wget https://jaist.dl.sourceforge.net/project/courier/courier-unicode/2.0/courier-unicode-2.0.tar.bz2
wget https://jaist.dl.sourceforge.net/project/courier/authlib/0.68.0/courier-authlib-0.68.0.tar.bz2
tar xf courier-unicode-2.0.tar.bz2
tar xf courier-authlib-0.68.0.tar.bz2
cd courier-unicode-2.0

--with-mailuser=postfix
make -j4 && make install
 
配置courier-authlib
echo "/usr/local/lib/courier-authlib/" > /etc/ld.so.conf.d/courier-authlib.conf
ldconfig
cp courier-authlib.sysvinit /etc/init.d/courier-authlib
chmod +x /etc/init.d/courier-authlib
cp /etc/authdaemonrc.dist /etc/authdaemonrc
cp /etc/authmysqlrc.dist /etc/authmysqlrc

MYSQL_GID_FIELD 2525
MYSQL_LOGIN_FIELD username
MYSQL_HOME_FIELD concat('/data/mailbox',homedir)
MYSQL_NAME_FIELD name
MYSQL_MAILDIR_FIELD concat('/data/mailbox',maildir)
 
修改SASL認證爲authdaemond
vim /etc/sasl2/smtpd.conf
cat /etc/sasl2/smtpd.conf
pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path:/usr/local/var/spool/authdaemon/socket
 
安裝並配置extman及extmail
wget http://7xivyw.com1.z0.glb.clouddn.com/extman-1.1.tar.gz
wget http://7xivyw.com1.z0.glb.clouddn.com/extmail-1.2.tar.gz
tar xf extman-1.1.tar.gz
tar xf extmail-1.2.tar.gz
mkdir /data/extsuite
mv extman-1.1 /data/extsuite/extman
mv extmail-1.2 /data/extsuite/extmail
cd /data/extsuite/
 
修改/data/extsuite目錄下全部配置文件中的/var/www字符爲/data
sed -i s@/var/www@/data@g find /data/extsuite -type f
 
修改extan和extmail的cgi目錄的屬主改組爲postfix
chown -R postfix:postfix /data/extsuite/{extman,extmail}/cgi
爲postfix提供extman官方給出的mysql虛擬域配置文件
cp -v /data/extsuite/extman/docs/mysqlvirtual* /etc/postfix/
‘/data/extsuite/extman/docs/mysql_virtual_alias_maps.cf’ -> ‘/etc/postfix/mysql_virtual_alias_maps.cf’

vim /etc/postfix/mysql_virtual_limit_maps.cf
vim /etc/postfix/mysql_virtual_mailbox_maps.cf
vim /etc/postfix/mysql_virtual_sender_maps.cf
 
修改extmail官方給出的mysql數據庫示例腳本再導入數據庫
sed -i s/TYPE=MyISAM/ENGINE=InnoDB/g extman/docs/extmail.sql
sed -i s/extmail.org/hehegame.com/g extman/docs/init.sql

修改extman官方提供的perl-cgi程序腳本的SU_UID和SU_GID都爲postfix
vim extmail/dispatch-init
grep ^SU extmail/dispatch-init
SU_UID=postfix
SU_GID=postfix
 
爲避免登陸extman以後 再登陸extmail以後提示sort文件名報錯作出以下修改
mv /data/extsuite/extman/libs/Ext/Utils.pm{,.bak}
cp /data/extsuite/extmail/libs/Ext/Utils.pm /data/extsuite/extman/libs/Ext/
 
修改extman默認記錄的用戶名爲空
vim /data/extsuite/extman/html/default/index.html
input name=username value='' class=login_input
 
yum安裝perl syslog所需組件
yum install -y perl-Unix-Syslog
 
編譯安裝Time-HiRes和/File-Tail這兩個perl組件，不然extman後臺的圖形分析日誌看不到，（必定要注意安裝的前後順序）
wget http://search.cpan.org/CPAN/authors/id/J/JH/JHI/Time-HiRes-1.9746.tar.gz
wget http://search.cpan.org/CPAN/authors/id/M/MG/MGRABNAR/File-Tail-1.3.tar.gz
tar xf Time-HiRes-1.9746.tar.gz
tar xf File-Tail-1.3.tar.gz

yum安裝nginx並提供虛擬主機配置文件
yum install -y nginx
sed -i '38,57s/^/#/' /etc/nginx/nginx.conf
vim /etc/nginx/conf.d/mail-server.conf
cat /etc/nginx/conf.d/mail-server.conf

Extmail+Extman架設好之後，打開extman顯示 No such file or directory是沒有啓動cmdserve腳本所致使的

至此一個基礎功能版本的開源郵件系統就能夠工做了，不足之處還望大神指教！
