Linux搭建postfix郵件服務器
systemctl start dovecot
service courier-authlib restart
systemctl status courier-authlib
systemctl enable courier-authlib
systemctl start saslauthd
systemctl enable saslauthd
-------postfix-------配置
一、 裝備工作
setenforce 0
systemctl stop firewalld
iptables -P INPUT ACCEPT
iptables -F
iptables -X
iptables -L
二、安裝mysql5.7 epel源
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
三、安裝postfix
1、卸載系統自帶的postfix，刪除postfix用戶，重新指定uid、gid創建新用戶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、下載源碼包並解壓編譯
wget http://mirrors.go-parts.com/postfix/source/official/postfix-3.0.1.tar.gz
tar xf postfix-3.0.1.tar.gz
cd postfix-3.0.1
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
3、更改目錄屬主屬組
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.everyoo.com //設置主機名
mydomain = everyoo.com //指定域名
myorigin = $mydomain //指明發件人所在的域名
inet_interfaces = //all指定postfix系統監聽的網絡接口
mydestination = $myhostname, localhost.$mydomain, localhost,$mydomain //指定postfix接收郵件時收件人的域名 [使用虛擬域需要禁用]
mynetworks_style = host //指定信任網段類型
mynetworks = 192.168.1.0/24, 127.0.0.0/8 //指定信任的客戶端
relay_domains = $mydestination //指定允許中轉郵件的域名
alias_maps = hash:/etc/aliases //設置郵件的別名
四、安裝dovecot
yum install -y dovecot dovecot-mysql
cd /etc/dovecot/
vim dovecot.conf
protocols = imap pop3
!include conf.d/*.conf
listen = *
base_dir = /var/run/dovecot/
cd conf.d/
vim 10-auth.conf
disable_plaintext_auth = no
vim 10-mail.conf
mail_location = maildir:~/Maildir
mail_location = maildir:/var/mailbox/%d/%n/Maildir
mail_privileged_group = mail
vim 10-ssl.conf
ssl = no
vim 10-logging.conf og_path = /var/log/dovecot.log
info_log_path = /var/log/dovecot.info
log_timestamp = "%Y-%m-%d %H:%M:%S "
cp auth-sql.conf.ext auth-sql.conf
vim auth-sql.conf
passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext}# Path for SQL configuration file, see example-config/dovecot-sql.conf.ext
userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext}
五、安裝courier-authlib
wget https://sourceforge.net/projects/courier/files/courier-unicode/1.2/courier-unicode-1.2.tar.bz2
tar xf courier-unicode-1.2.tar.bz2
cd courier-unicode-1.2
./configure
make && make install
wget https://sourceforge.net/projects/courier/files/authlib/0.66.2/courier-authlib-0.66.2.tar.bz2
tar xf courier-authlib-0.66.2.tar.bz2
cd 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
make && make install
2、配置courier-authlib
chmod 755 /usr/local/courier-authlib/var/spool/authdaemon
cp /etc/authdaemonrc.dist /etc/authdaemonrc
cp /etc/authmysqlrc.dist /etc/authmysqlrc
vim /etc/authdaemonrc
authmodulelist="authmysql"
authmodulelistorig="authmysql"
vim /etc/authmysqlrc
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)
3、courier-authlib添加服務啟動腳本及其他
cp courier-authlib.sysvinit /etc/init.d/courier-authlib
chmod +x /etc/init.d/courier-authlib
chkconfig --add courier-authlib
chkconfig courier-authlib on
echo "/usr/local/courier-authlib/lib/courier-authlib" >> /etc/ld.so.conf.d/courier-authlib.conf
ldconfig
service courier-authlib start
4、smtp以及虛擬用戶相關的設置
vim /usr/lib64/sasl2/smtpd.conf //文件不存在，要自己創建
pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket
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支持虛擬用戶##
virtual_mailbox_base = /var/mailbox
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf //這裏的配置文件需在後面extman
裏復制過來
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
六、安裝extmail
extmail和extman可通過這兩個鏈接下載
http://7xivyw.com1.z0.glb.clouddn.com/extmail-1.2.tar.gz
http://7xivyw.com1.z0.glb.clouddn.com/extman-1.1.tar.gz
mkdir -p /var/www/extsuite
tar xf extmail-1.2.tar.gz -C /var/www/extsuite/
mv /var/www/extsuite/extmail-1.2/ /var/www/extsuite/extmail
2、更改extmail的配置文件
cd /var/www/extsuite/extmail
cp webmail.cf.default webmail.cf
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
3、建立臨時文件目錄與session目錄
mkdir -p /tmp/extmail/upload
chown -R postfix.postfix /tmp/extmail/
七、安裝extman
tar xf extman-1.1.tar.gz -C /var/www/extsuite/
cd /var/www/extsuite/
mv extman-1.1/ extman
2、更改extman配置文件
cd extman/
cp webman.cf.default webman.cf
3、更改cgi目錄屬主屬組
chown -R postfix.postfix /var/www/extsuite/extman/cgi/
chown -R postfix.postfix /var/www/extsuite/extmail/cgi/
4、導入數據庫
vim docs/extmail.sql
:% s/TYPE/ENGINE/g
vim /etc/my.cnf
# Recommended in standard MySQL setup
#sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES //將這行註視掉，重啟mysql，這裏需要註意的是，等數據庫導入成功後，這項是不可以去掉註釋的，不然mysql就啟動不起來了。
mysql -uroot < docs/extmail.sql
mysql -uroot < docs/init.sql
5、創建數據庫用戶extmail並授予權限
GRANT ALL ON extmail.* to extmail@'%' identified by 'extmail';
FLUSH PRIVILEGES;
6、復制四-4提到的配置文件
cd /var/www/extsuite/extman/docs/
cp mysql_virtual_* /etc/postfix/
mkdir /tmp/extman
chown -R postfix.postfix /tmp/extman/
7、啟動postfix、dovecot、saslauthd
ss -tnluo | grep :25
ps aux | grep dovecot
ps aux | grep saslauthd
八、測試
/usr/local/courier-authlib/sbin/authtest -s login [email protected] extmail
mkdir /var/mailbox
chown -R postfix.postfix /var/mailbox/
vim /etc/nginx/fcgi.conf
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;
wget http://www.cpan.org/authors/id/M/MH/MHARNISCH/Unix-Syslog-1.1.tar.gz
tar xf Unix-Syslog-1.1.tar.gz
cd Unix-Syslog-1.1
perl Makefile.PL
make && make install
安裝證書到postfix，並配置postfix
vi /etc/postfix/main.cf
smtpd_use_tls = yes
smtpd_tls_key_file = /etc/postfix/mailkey.pem
smtpd_tls_cert_file = /etc/postfix/mail_signed_cert.pem
smtpd_tls_CAfile = /etc/postfix/cacert.pem
smtp_use_tls = yes
smtp_tls_note_starttls_offer = yes
smtp_tls_key_file = /etc/postfix/mailkey.pem
smtp_tls_cert_file = /etc/postfix/mail_signed_cert.pem
smtp_tls_CAfile = /etc/postfix/cacert.pem
service postfix restart
打開465（smtps)端口，則需要進行進行如下操作
修改/etc/postfix/master.cf文件
在smtp inet n - n - - smtpd行下，加入如下一行：
smtps inet n - n - - smtpd -o smtpd_tls_wrappermode=yes
vi /etc/dovecot/conf.d/10-ssl.conf
ssl = yes
ssl_cert = </etc/pki/tls/certs/server.crt
ssl_key = </etc/pki/tls/certs/server.key
