一、软件的准备
A.检查你的系统是否已安装了以下软件
1.pam
2.pam-devel
3.mysql
4.mysql-servel
5.mysql-devel
6.imap-devel
7.sharutils
B.下载以下软件
1.metamail*.i386.rpm
2.pam-mysql
3.cyrus-sasl-2.1.15
4.postfix-2.0.16
5.courier-imap
C.说明
mysql-devel在第3个盘。我忘了装，结果pam-mysql和postfix的编译过不了。metamail和sharutils是取验证码用的。
二、mysql数据库和表的建立
A.[root@localhost root]# mysql
Welcome to the MySQL monitor.
Commands end with ; or \g.
Your MySQL connection id is 3 to server version: 3.23.58
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql INSERT INTO db (Host,Db,User,Select_priv)VALUES('localhost','postfix','postfix','Y');
Query OK, 1 row affected (0.00 sec)
mysql CREATE DATABASE postfix;
Query OK, 1 row affected (0.00 sec)
mysql GRANT ALL ON postfix.* TO postfix@localhost
- IDENTIFIED BY "postfix";
Query OK, 0 rows affected (0.00 sec)
mysql FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
mysql quit
Bye
B.把下列文字复制存为postfix.sql
########potfix_sql########bigin##################
CREATE TABLE alias (
username varchar(255) NOT NULL default'',
goto text NOT NULL,

domain表的解释:
domain 任意的domain.
description 通常是2种 "local:" 用于本地的 or "virtual:" 用于是虚拟的.
alias表的解释:
username 是虚拟的邮箱address@domain.tld ，将被转发到goto下的联结中.
goto 可以用简单的名字，如果是本地用户名，如(root, postmaster, etc.), 或者是整个的邮箱名字，user@domain.tld。
Mailbox表的内容:
Userid 使用者编码
username 可以是user.domain.tld 或 user@domain.tld
password 在mysql中用encrypt('password') 输入.
name 使用着的真实姓名。
uid 虚拟用户身份uid
gid 组的gid
home "/usr/local/virtual/". Maildirs必须在此目录下。
domain 这栏可以不要，但有些软件需要他。
maildir 是整个地址，必须带”/”结尾。
Quota 邮箱的空间或信息量的限制。
status 0 为禁止。"MYSQL_WHERE_CLAUSE= status"
.
三、pam-mysql的编译
tar pam-mysql-5.0.tar.gz
make cp pam_mysql.so /lib/security
四、修改pam
[root@localhost
pam_mysql]#
cd
/etc/pam.d
[root@localhost
pam.d]#
cp
/work/postfix
postfix
[root@localhost
pam.d]#
postfix的内容如下：
##########/etc/pam.d/postfix##################
echo
auth
sufficient
pam_mysql.so
user=postfix
passwd=postfix
host=localhost
db=postfix
table=mailbox
usercolumn=username
