十、安装postfix邮件帐号后台web管理工具

   ftp://postfix.cn99.com/postfix/index.html

#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

#cp /usr/local/mysql/lib/mysql/libmysqlclient.so.15 /usr/lib[f1] 

#make install

install_root: [/] 
tempdir: [/soft// postfix-2.4.5]
 /tmp
config_directory: [/etc/postfix]
 
command_directory: [/usr/sbin] 
/usr/local/postfix/sbin
daemon_directory: [/usr/libexec/postfix] /usr/local/postfix/libexec
data_directory: [/var/lib/postfix]
  
html_directory: [no] 
/var/www/postfix_html  

mail_owner: [postfix]

mailq_path: [/usr/bin/mailq]

manpages: [/usr/local/man] /usr/local/postfix/man

newaliases_path: [/usr/bin/newaliases]

queue_directory: [/var/spool/postfix]

readme_directory: [no]
sendmail_path: [/usr/sbin/sendmail]
setgid_group: [postdrop]

生成别名二进制文件,这个步骤如果忽略,会造成postfix效率极低:
# mv /etc/aliases /etc/aliases.OFF
#ln -sv /etc/postfix/aliases /etc/aliases
#newaliases
#vim /etc/postfix/main.cf

修改以下几项为您需要的配置
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

说明:
myorigin
参数用来指明发件人所在的域名;
mydestination
参数指定postfix接收邮件时收件人的域名,即您的postfix系统要接收到哪个域名的邮件;
myhostname 
参数指定运行postfix邮件系统的主机的主机名,默认情况下,其值被设定为本地机器名;
mydomain
参数指定您的域名,默认情况下,postfixmyhostname的第一部分删除而作为mydomain的值;
mynetworks 
参数指定你所在的网络的网络地址,postfix系统根据其值来区别用户是远程的还是本地的,如果是本地网络用户则允许其访问;
inet_interfaces 
参数指定postfix系统监听的网络接口;
注意:
1
、在postfix的配置文件中,参数行和注释行是不能处在同一行中的;
2
、任何一个参数的值都不需要加引号,否则,引号将会被当作参数值的一部分来使用;
3
、每修改参数及其值后执行 postfix reload 即可令其生效;但若修改了inet_interfaces,则需重新启动postfix
4
、如果一个参数的值有多个,可以将它们放在不同的行中,只需要在其后的每个行前多置一个空格即可;postfix会把第一个字符为空格或tab的文本行视为上一行的延续;

启动postfix

# /usr/local/postfix/sbin/postfix start

#echo  '/usr/local/postfix/sbin/postfix start' >> /etc/rc.local

#useradd test

# telnet localhost 25

Trying 127.0.0.1...

 [f1]如果配置没有提示需要拷贝该库文件到指定位置

十一、为postfix开启基于cyrus-sasl的认证

使用以下命令验正postfix是否支持cyrus风格的sasl认证,如果您的输出为以下结果,则是支持的

# /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

postfix重新加载配置文件

# /usr/local/postfix/sbin/postfix reload

telnet localhost 25

Trying 127.0.0.1...

Connected to localhost.localdomain (127.0.0.1).

Escape character is '^]'.

220 Welcome to our mail.test.com ESMTP,Warning: Version not Available!

ehlo mail.test.com

250-mail.test.com

250-PIPELINING

250-SIZE 10240000

250-VRFY

250-ETRN

250-AUTH PLAIN LOGIN

250-AUTH=PLAIN LOGIN

[f1] 250-ENHANCEDSTATUSCODES

250-8BITMIME

250 DSN

 [f1]有这两行输出即可

十二、postfix支持虚拟域和虚拟用户

#vim /etc/postfix/main.cf

文件最后添加以下内容:

########################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

写入以下内容:

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:
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = domain
select_field = description
where_field = domain

#vim /etc/postfix/mysql_virtual_mailbox_limit_maps.cf

写入以下内容:
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = quota
where_field = username

#vim /etc/postfix/mysql_virtual_mailbox_maps.cf

写入以下内容:
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = maildir
where_field = username

这里用到的数据库及用户的建立可以后文中的extmail说明部分来实现,您可以参照那一部分来理解这里指定的数据库及其用户名等

十三、安装courier-authlib用于sasl用户密码的认证

      www.courier-mta.org/authlib/

#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

#make install

#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

修改以下三个配置项:

authmodulelist="authmysql"
authmodulelistorig="authmysql"
daemons=10

#>/etc/authmysqlrc

#vim /etc/authmysqlrc

写入以下内容:

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、安装courier-imapPop3IMAP服务

www.courier-mta.org/imap/

# 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'

#make

#make install

# 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,为用户提供pop3服务:
#vim /usr/local/courier-imap/etc/pop3d

修改下面配置项针对pop3协议支持
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

#vim /usr/local/lib/sasl2/smtpd.conf

文件末尾写入以下内容
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

未完待续.......
