笔记postfix + cyrus-sasl2 + courier-authlib + Courier-IMAP + postfixadmin

1.安装cyrus-sasl-2.x
删除以前的rpm包以及相关目录
rpm -e --nodeps cyrus-sasl-2.1.10-4 cyrus-sasl-plain-2.1.10-4 cyrus-sasl-md5-2.1.10-4 cyrus-sasl-devel-2.1.10-4
rm -rf /usr/lib/sasl
rm -rf /usr/lib/sasl2

wget  ftp://ftp.andrew.cmu.edu/pub/cyrus-mail/cyrus-sasl-2.1.21.tar.gz

./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=/usr/local/mysql --with-mysql-includes=/usr/local/mysql/include/mysql --with-mysql-

libs=/usr/local/mysql/lib/mysql

make
make install

ln -s /usr/local/lib/sasl2 /usr/lib/sasl2

增加"/usr/local/lib"到你的"/etc/ld.so.conf"，并执行ldconfig命令。

vi /usr/local/lib/sasl2/smtpd.conf

pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket
注意，这个文件的编辑不要多写一个空格，否则会出现smtp验证不过的问题

2.编译postfix2.x

wget ftp://postfix.cn99.com/postfix/official/postfix-2.2.10.tar.gz

tar zvxf postfix-2.2.10.tar.gz

下载VDA补丁,使postfix支持磁盘限额
wget http://web.onda.com.br/nadal/postfix/VDA/postfix-2.2.10-vda.patch.gz

gzip -d  postfix-2.2.10-vda.patch.gz

chkconfig --level 2345 sendmail off

安装postfix之前添加相关的用户＆用户组
groupadd postfix -g 1000
groupadd postdrop
useradd postfix -u 1000 -g postfix -G postdrop
groupadd vmail -g 1001
useradd vmail -u 1001 -g 1001
mkdir /home/mail
chown vmail:vmail /home/mail
chmod -R 771 /home/mail

打补丁
patch -p1 < ../postfix-2.2.10-vda.patch

make tidy

make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/local/mysql/include/mysql -DUSE_SASL_AUTH -I/usr/local/include/sasl' 'AUXLIBS=-

L/usr/local/mysql/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

touch /etc/postfix/mysql_virtual_alias_maps.cf
touch /etc/postfix/mysql_virtual_domains_maps.cf
touch /etc/postfix/mysql_virtual_mailbox_maps.cf

virtual_minimum_uid = 1001

#"virtual_gid_maps"和"virtual_uid_maps"是postfix用户的gid和uid， "virtual_minimum_uid"应当≤"virtual_uid_maps"，

"virtual_mailbox_limit"是每个邮箱的大小。

sample_directory = /etc/postfix

编辑cf配置文件

vi /etc/postfix/mysql_virtual_alias_maps.cf

user = postfix
password = postfix
hosts = localhost
dbname = postfix
table = alias
select_field = goto
where_field = address
additional_conditions = AND active = '1'

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

vi /etc/postfix/mysql_virtual_domains_maps.cf

user = postfix
password = postfix
hosts = localhost
dbname = postfix
table = domain
select_field = description
where_field = domain
additional_conditions = AND active = '1'

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

vi /etc/postfix/mysql_virtual_mailbox_maps.cf

user = postfix
password = postfix
hosts = localhost
dbname = postfix
table = mailbox
select_field = maildir
where_field = username
additional_conditions = AND active = '1'

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

vi /etc/postfix/mysql_virtual_limit_maps.cf

user = postfix
password = postfix
hosts = localhost
dbname = postfix
table = mailbox
select_field = quota
where_field = username
additional_conditions = AND active = '1'

启动和挺直postfix服务
/usr/sbin/postfix start
/usr/sbin/postfix stop

3.编译courier-authlib

wget http://kent.dl.sourceforge.net/sourceforge/courier/courier-authlib-0.58.tar.bz2

tar jvxf courier-authlib-0.58.tar.bz2

./configure
--prefix=/usr/local/courier-authlib --without-stdheaderdir
--without-authuserdb --without-authpam --without-authldap --without-authpwd --without-authshadow --without-authvchkpw --without-authpgsql --without-authcustom
--with-authmysql --with-mysql-libs=/usr/local/mysql/lib/mysql --with-mysql-includes=/usr/local/mysql/include/mysql
--with-redhat

一个关键点：

如果courier-authlib安装到非标准位置（例如安装到/usr/local下），一定记得在./configure时增加--without-stdheaderdir，这样以后在编译Courier-IMAP和maildrop的时候，不用特别指定courier-authlib的库文件位置

make
make install
make install-configure

增加"/usr/local/courier-authlib/lib/courier-authlib"到你的"/etc/ld.so.conf"，并执行ldconfig命令。
chmod +x /usr/local/courier-authlib/var/spool/authdaemon

vi /usr/local/courier-authlib/etc/authlib/authdaemonrc    可以不修改
authmodulelist="authmysql"
authmodulelistorig="authmysql"
daemons=10

vi /usr/local/courier-authlib/etc/authlib/authmysqlrc

MYSQL_SERVER localhost
MYSQL_USERNAME postfix
MYSQL_PASSWORD yourpassword

MYSQL_SOCKET /tmp/mysql.sock

MYSQL_DATABASE postfix
MYSQL_USER_TABLE mailbox

MYSQL_CRYPT_PWFIELD password

MYSQL_UID_FIELD 1001
MYSQL_GID_FIELD 1001

MYSQL_LOGIN_FIELD username
MYSQL_HOME_FIELD '/home/mail/' #设置postfix存储邮件的目录
MYSQL_NAME_FIELD name

MYSQL_MAILDIR_FIELD maildir
MYSQL_QUOTA_FIELD quota
MYSQL_WHERE_CLAUSE active='1'

启动courier-authlib
/usr/local/courier-authlib/sbin/authdaemond start

4.编译安装安装Courier-IMAP

wget http://surfnet.dl.sourceforge.net/sourceforge/courier/courier-imap-4.1.0.tar.bz2
tar jvxf courier-imap-4.1.0.tar.bz2

./configure --prefix=/usr/local/courier-imap --with-redhat --enable-unicode --disable-root-check --with-trashquota --without

-ipv6 CPPFLAGS='-I/usr/local/courier-authlib/include' COURIERAUTHCONFIG='/usr/local/courier-authlib/bin/courierauthconfig'

CPPFLAGS='-I/usr/local/courier-authlib/include'    如果编译courier-authlib没有安装在默认路径，必须指定这个，如果之前编译courier-authlib加了--without-stdheaderdir，就不需要指定了

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：
vi /usr/local/courier-imap/etc/pop3d
POP3DSTART=yes
 注：如果你想为用户提供IMAP服务，可以在"/usr/local/courier-imap/etc/imapd"文件中设置"IMAPDSTART=yes"。

cp courier-imap.sysvinit /etc/rc.d/init.d/imapd
chmod 755 /etc/rc.d/init.d/imapd
chkconfig --add imapd

5.编译安装postfixadmin

wget http://high5.net/postfixadmin/download.php?file=postfixadmin-2.1.0.tgz

tar -zxvf postfixadmin-2.1.0.tgz

把解压的目录改名拷贝到默认的web目录下，比如 /var/www

cd /var/www/postfixadmin

$ chmod 640 *.php *.css
$ cd /var/www/postfixadmin/admin
$ chmod 640 *.php .ht*
$ cd /var/www/postfixadmin/images/
$ chmod 640 *.gif *.png
$ cd /var/www/postfixadmin/languages/
$ chmod 640 *.lang
$ cd /var/www/postfixadmin/templates/
$ chmod 640 *.tpl
$ cd /var/www/postfixadmin/users/
$ chmod 640 *.php

导入数据库

mysql -uroot -p  < DATABASE_MYSQL.TXT

访问：
http://域名/postfixadmin/

 

6.FAQ：
1.出现authentication error: Input/output error错误的时候
估计是查询mysql时，authdaemond出错了。具体要打开authdaemonrc里的：

DEBUG_LOGIN=2    原来默认是0

然后看看/var/log/message或/var/log/maillog 在认证失败时有什么提示。根据提示去检查问题到底出在哪儿

2.warning: SASL authentication failure: cannot connect to Courier authdaemond: Permission denied
检查 authdaemond的socket所在目录及其父目录的属性是否对smtpd可读。如果不可读则出现这个问题（permission的问题）。

3.warning: SASL authentication failure: cannot connect to Courier authdaemond: No such file or directory
检查/usr/local/lib/sasl2/smtpd.conf，看看是否有多写一个空格，一般空格很难直观的发现
