<b>十、安裝</b><b>postfix</b><b>（</b>郵件帳号背景web管理工具<b>）</b>
#groupadd -g 2525 postfix
#useradd -g postfix -u 2525 -s /sbin/nologin -M postfix
#groupadd -g 2526 postdrop
#useradd -g postdrop -u 2526 -s /bin/false -M postdrop
#tar zxvf postfix-2.6-20080824.tar.gz -C /usr/local/src/
#cd /usr/local/src/postfix-2.6-20080824/
#make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/local/mysql/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/local/sasl2/include/sasl -I/usr/local/BerkeleyDB/include-DUSE_TLS -I/usr/local/ssl/include/openssl ' 'AUXLIBS=-L/usr/local/mysql/lib/mysql -lmysqlclient -lz -lm -L/usr/local/sasl2/lib -lsasl2 -L/usr/local/BerkeleyDB/lib -L/usr/local/ssl/lib -lssl -lcrypto'
#make
#make install
<b>install_root: [/] </b>
<b>tempdir: [/soft// postfix-2.4.5]</b><b> /tmp</b>
<b>config_directory: [/etc/postfix]</b><b> </b>
<b>command_directory: [/usr/sbin] </b><b>/usr/local/postfix/sbin</b>
<b>daemon_directory: [/usr/libexec/postfix] /usr/local/postfix/libexec</b>
<b>data_directory: [/var/lib/postfix]</b><b> </b><b></b>
html_directory: [no] <b>/var/www/postfix_html</b><b> </b>
<b>mail_owner: [postfix]</b>
<b>mailq_path: [/usr/bin/mailq]</b>
<b>manpages: [/usr/local/man] </b><b>/usr/local/postfix/man</b>
<b>newaliases_path: [/usr/bin/newaliases]</b>
<b>queue_directory: [/var/spool/postfix]</b>
<b>readme_directory: [no]</b>
<b>sendmail_path: [/usr/sbin/sendmail]</b>
<b>setgid_group: [postdrop]</b>
生成别名二進制檔案，這個步驟如果忽略，會造成postfix效率極低：<b></b>
# mv /etc/aliases /etc/aliases.OFF
#ln -sv /etc/postfix/aliases /etc/aliases
#newaliases
#vim /etc/postfix/main.cf<b></b>
修改以下幾項為您需要的配置
myhostname = mail.test.com
myorigin = test.com
mydomain = test.com
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mynetworks = 172.16.0.0/16, 127.0.0.0/8
說明:
myorigin參數用來指明發件人所在的域名；
mydestination參數指定postfix接收郵件時收件人的域名，即您的postfix系統要接收到哪個域名的郵件；
myhostname 參數指定運作postfix郵件系統的主機的主機名，預設情況下，其值被設定為本地機器名；
mydomain參數指定您的域名，預設情況下，postfix将myhostname的第一部分删除而作為mydomain的值；
mynetworks 參數指定你所在的網絡的網絡位址，postfix系統根據其值來差別使用者是遠端的還是本地的，如果是本地網絡使用者則允許其通路；
inet_interfaces 參數指定postfix系統監聽的網絡接口；
注意：
1、在postfix的配置檔案中，參數行和注釋行是不能處在同一行中的；
2、任何一個參數的值都不需要加引号，否則，引号将會被當作參數值的一部分來使用；
3、每修改參數及其值後執行 postfix reload 即可令其生效；但若修改了inet_interfaces，則需重新啟動postfix；
4、如果一個參數的值有多個，可以将它們放在不同的行中，隻需要在其後的每個行前多置一個空格即可；postfix會把第一個字元為空格或tab的文本行視為上一行的延續；
啟動postfix
# /usr/local/postfix/sbin/postfix start
#echo '/usr/local/postfix/sbin/postfix start' >> /etc/rc.local
#useradd test
# telnet localhost 25

<b>十一、為</b><b>postfix</b><b>開啟基于</b><b>cyrus-sasl</b><b>的認證</b>
使用以下指令驗正postfix是否支援cyrus風格的sasl認證，如果您的輸出為以下結果，則是支援的
# /usr/local/postfix/sbin/postconf -a
cyrus
dovecot
#vim /etc/postfix/main.cf
最下面添加以下内容：
############################CYRUS-SASL############################
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject_invalid_hostname,reject_non_fqdn_hostname,reject_unknown_sender_domain,reject_non_fqdn_sender,reject_non_fqdn_recipient,reject_unknown_recipient_domain,reject_unauth_pipelining,reject_unauth_destination
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_security_options = noanonymous
smtpd_sasl_application_name = smtpd
smtpd_banner = Welcome to our $myhostname ESMTP,Warning: Version not Available!
#vim /usr/local/lib/sasl2/smtpd.conf
添加如下内容：
pwcheck_method: saslauthd
mech_list: PLAIN LOGIN
讓postfix重新加載配置檔案
# /usr/local/postfix/sbin/postfix reload
220 Welcome to our mail.test.com ESMTP,Warning: Version not Available!
<a>250-AUTH PLAIN LOGIN</a>
250-AUTH=PLAIN LOGIN
十二、<b>讓</b><b>postfix</b><b>支援虛拟域和虛拟使用者</b>
<b>#</b>vim /etc/postfix/main.cf
檔案最後添加以下内容：
########################Virtual Mailbox Settings########################
virtual_mailbox_base = /var/mailbox/
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
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
maildrop_destination_recipient_limit = 1
maildrop_destination_concurrency_limit = 1
##########################QUOTA Settings########################
message_size_limit = 14336000
virtual_mailbox_limit = 20971520
virtual_create_maildirsize = yes
virtual_mailbox_extended = yes
virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_mailbox_limit_maps.cf
virtual_mailbox_limit_override = yes
virtual_maildir_limit_message = Sorry, the user's maildir has overdrawn his diskspace quota, please Tidy your mailbox and try again later.
virtual_overquota_bounce = yes
# vim /etc/postfix/mysql_virtual_alias_maps.cf
寫入以下内容：
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = alias
select_field = goto
where_field = address
#vim /etc/postfix/mysql_virtual_domains_maps.cf
添加以下内容：
table = domain
select_field = description
where_field = domain
#vim /etc/postfix/mysql_virtual_mailbox_limit_maps.cf
table = mailbox
select_field = quota
where_field = username
#vim /etc/postfix/mysql_virtual_mailbox_maps.cf
select_field = maildir
這裡用到的資料庫及使用者的建立可以後文中的extmail說明部分來實作，您可以參照那一部分來了解這裡指定的資料庫及其使用者名等
<b>十三、安裝</b><b>courier-authlib</b><b>（</b><b>用于</b><b>sasl</b><b>使用者密碼的認證</b><b>）</b>
#yum install gdbm-devel
#tar zxvf courier-authlib_0.61.0.orig.tar.gz -C /usr/local/src/
#cd /usr/local/src/courier-authlib-0.61.0.orig/
#./configure --prefix=/usr/local/courier-authlib --sysconfdir=/etc --without-authpam --without-authldap --without-authpwd --without-authshadow --without-authvchkpw --without-authpgsql --with-authmysql --with-mysql-libs=/usr/local/mysql/lib/mysql --with-mysql-includes=/usr/local/mysql/include/mysql --with-redhat --with-authmysqlrc=/etc/authmysqlrc --with-authdaemonrc=/etc/authdaemonrc CFLAGS="-march=i686 -O2 -fexpensive-optimizations" CXXFLAGS="-march=i686 -O2 -fexpensive-optimizations"
#make install-migrate
#make install-configure
# chmod 755 /usr/local/courier-authlib/var/spool/authdaemon
# cp /etc/authdaemonrc.dist /etc/authdaemonrc
# cp /etc/authmysqlrc.dist /etc/authmysqlrc
#vim /etc/authdaemonrc
修改以下三個配置項：
authmodulelist="authmysql"
authmodulelistorig="authmysql"
daemons=10
#>/etc/authmysqlrc
#vim /etc/authmysqlrc
MYSQL_SERVER localhost
MYSQL_PORT 3306
MYSQL_USERNAME extmail
MYSQL_PASSWORD extmail
MYSQL_SOCKET /tmp/mysql.sock
MYSQL_DATABASE extmail
MYSQL_USER_TABLE mailbox
MYSQL_CRYPT_PWFIELD password
MYSQL_UID_FIELD '2525'
MYSQL_GID_FIELD '2525'
MYSQL_LOGIN_FIELD username
MYSQL_HOME_FIELD concat('/var/mailbox/',maildir)
MYSQL_NAME_FIELD name
MYSQL_MAILDIR_FIELD concat('/var/mailbox/',maildir)
# cp courier-authlib.sysvinit /etc/init.d/courier-authlib
# chmod 755 /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
# ldconfig -v
# service courier-authlib start
十四、<b>安裝</b><b>courier-imap</b><b>（</b>Pop3及IMAP服務<b>）</b>
<a href="http://www.courier-mta.org/imap/" target="_blank">www.courier-mta.org/imap/</a>
# tar jxvf courier-imap-4.1.0.tar.tar -C /usr/local/src/
# cd /usr/local/src/courier-imap-4.1.0/
#./configure --prefix=/usr/local/courier-imap --with-redhat --enable-unicode --disable-root-check --with-trashquota --without-ipv6 CPPFLAGS='-I/usr/local/ssl/include/openssl -I/usr/local/courier-authlib/include' LDFLAGS='-L/usr/local/courier-authlib/lib/courier-authlib' COURIERAUTHCONFIG='/usr/local/courier-authlib/bin/courierauthconfig<b>'</b>
# cp /usr/local/courier-imap/etc/imapd.dist /usr/local/courier-imap/etc/imapd
# cp /usr/local/courier-imap/etc/imapd-ssl.dist /usr/local/courier-imap/etc/imapd-ssl
# cp /usr/local/courier-imap/etc/pop3d.dist /usr/local/courier-imap/etc/pop3d
# cp /usr/local/courier-imap/etc/pop3d-ssl.dist /usr/local/courier-imap/etc/pop3d-ssl
配置Courier-IMAP，為使用者提供pop3服務：
#vim /usr/local/courier-imap/etc/pop3d
修改下面配置項針對pop3協定支援
POP3DSTART=YES
#mkdir -pv /var/mailbox
# chown -R postfix:postfix /var/mailbox
#cp courier-imap.sysvinit /etc/rc.d/init.d/courier-imapd
#chmod 755 /etc/rc.d/init.d/courier-imapd
#chkconfig --add courier-imapd
#chkconfig --level 2345 courier-imapd on
#service courier-imapd start
檔案末尾寫入以下内容
pwcheck_method: authdaemond
log_level: 3
mech_list: LAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket
allow_plaintext: true
auxprop_plugin: mysql
sql_hostnames: localhost
sql_user: extmail
sql_passwd: extmail
sql_database: extmail
sql_select: select password from mailbox where username='%u'
#/etc/init.d/courier-authlib restart
未完待續.......
