CENTOS5下配置mail服务器

CENTOS5，Fedora8下配置mail服务器
在Fedora8下比CENTOS5下配置更顺利

[QQ:48238398][抄来抄去，呵]
说明：apache,php,mysql,为centos5自带的，就是说我装系统的时候，就选择上了：
cyrus-sasl,postfix,courier-authlib，maildrop ，courier-imap 是通过源码编译的，
写这个的目的就是，复制内容，照着一步步的做下去就能配置出来一个成功的可视化管理的mail服务器

如果是rpm方式按装的msqyl,include及lib目录的位置
/usr/include/mysql /usr/lib/mysql
如果是编译的，位于你指定的目录下，如果编译mysql指定目录为/usr/local/mysql则位于
/usr/local/mysql/include/mysql /usr/local/mysql/lib/mysql

开始：：：
如果你的apache,php,mysqsl是centos5自带的，就是说不是你自己编译的，以下的代码可以复制粘

贴直接用
=cyrus-sasl=按装配置cyrus-sasl
=cyrus-sasl=下载地址：ftp://ftp.andrew.cmu.edu/pub/cyrus-mail/
=cryus-sasl=文件名：cyrus-sasl-2.1.22.tar.gz
#rpm -qa|grep cyrus-sasl把查找出来的包都删除了
#rpm -e --nodeps 包名
#rm -rf /usr/lib/sasl
#rm -rf /usr/lib/sasl2
=cyrus-sasl=进入解压目录编译：
#./configure \
--enable-plain \
--enable-cram \
--enable-digest \
--enable-login \
--enable-sql \
--disable-anon \
--disable-ntlm \
--disable-gssapi \
--disable-krb4 \
--disable-otp \
--disable-srp \
--disable-srp-setpass \
-with-authdaemond=/usr/local/courier-authlib/var/spool/authdaemon/socket \
--with-mysql

#make
#make install
#ln -s /usr/local/lib/sasl2 /usr/lib/sasl2
#vi /etc/ld.so.conf
/usr/local/lib //增加该行
# ldconfig
# vi /usr/local/lib/sasl2/smtpd.conf
加入以下四行
pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket


==postfix==按装配置postfix
==postfix==下载地址：http://www.postfix.org/download.html
==postfix==文件名：postfix-2.4.6.tar.gz
==postfix==进入解压目录编译：
# yum install db*-devel*
# make tidy
# groupadd postfix -g 54321 //如果原来系统中有该用户则不需要再建
# groupadd postdrop
# useradd -s /bin/false -u 54321 -g postfix -G postdrop postfix
==postfix==备注，我的mysql是rpm包装的，如果是你自己源码编译的，下边mysql路径会有变化
#make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql -DUSE_CYRUS_SASL -DUSE_SASL_AUTH -I/usr/local/include/sasl' 'AUXLIBS=-L/usr/lib/mysql -lmysqlclient -lm -lz -L/usr/local/lib -lsasl2'
#make
#make install
#mv /etc/aliases /etc/aliases.old
#ln -s /etc/postfix/aliases /etc/aliases
#echo 'root: admin@example.com'>>/etc/postfix/aliases
#/usr/bin/newaliases

#postconf -n > /etc/postfix/main2.cf
#mv /etc/postfix/main.cf /etc/postfix/main.cf.old
#mv /etc/postfix/main2.cf /etc/postfix/main.cf
# vi /etc/postfix/main.cf
==postfix==main.cf加入以下内容
# hostname
mynetworks = 127.0.0.1
myhostname = mail.extmail.org
mydomain = extmai.com
myorigin = $mydomain
mydestination = $mynetworks $myhostname

# banner
mail_name = Postfix - by extmail.org
smtpd_banner = $myhostname ESMTP $mail_name

# response immediately
smtpd_error_sleep_time = 0s
unknown_local_recipient_reject_code = 450

# extmail config here
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_transport = maildrop:
==postfix==main.cf内容结束
==postfix==以下几个文件可以通过cp /var/www/html/extsuite/extman/docs/mysql_*

/etc/postfix/得到
==postfix==编辑mysql_virtual_alias_maps.cf
vi /etc/postfix/mysql_virtual_alias_maps.cf
内容如下：
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = alias
select_field = goto
where_field = address

==postfix==编辑mysql_virtual_domains_maps.cf
vi /etc/postfix/mysql_virtual_domains_maps.cf
内容如下：
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = domain
select_field = description
where_field = domain
#additional_conditions = and backupmx ='0' and active ='1'

==postfix==编辑mysql_virtual_mailbox_maps.cf
vi /etc/postfix/mysql_virtual_mailbox_maps.cf
内容如下：
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = maildir
where_field = username
#additional_conditions = and active = '1'


==postfix==SMTP认证需要透过Cyrus-SASL，连接到authdaemon获取认证信息，编

辑/etc/postfix/main.cf，增加如下内容：

# smtpd related config
smtpd_recipient_restrictions =
    permit_mynetworks,
   permit_sasl_authenticated,
   reject_non_fqdn_hostname,
   reject_non_fqdn_sender,
   reject_non_fqdn_recipient,
   reject_unauth_destination,
   reject_unauth_pipelining,
   reject_invalid_hostname,

# SMTP AUTH config here
broken_sasl_auth_clients = yes
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_security_options = noanonymous
