postfix+postfixadmin+extmail邮件服务器架设过程
近段時間由于工作原因，沒有完成......
六、SASL、Authlib安裝和配置
先安裝courier-authlib，因為后面配置 SASL驗證smtp時需要authlib的socket路徑。
1、???????? courier-authlib安裝和配置(實現帶驗證的pop3服務器)
[root@localhost courier-authlib-0.63.0]# ./configure --prefix=/usr/local/authlib --without-sthheaderdir --with-mysql-libs=/usr/local/mysql/lib/mysql --with-mysql-includes=/usr/local/mysql/include/mysql --with-redhat --with-mailuser=vmail? --with-mailgroup=vmail? --with-authmysql
如果courier-authlib安裝到非標準位置（例如安裝到/usr/local下），一定記得在./configure時增加--without-stdheaderdir，這樣以后在編譯Courier-IMAP和maildrop的時候，不用特別指定courier-authlib的庫文件位置
configure: error: Cannot find either the gdbm or the db library.
解決方法:安裝安裝rpm -ihv gdbm-devel-1.8.0-25.i386.rpm
[root@localhost courier-authlib-0.63.0]# Make && make install
[root@localhost courier-authlib-0.63.0]#make install-migrate
[root@localhost courier-authlib-0.63.0]#make install-configure
[root@localhost courier-authlib-0.63.0]#vi /usr/local/authlib/etc/authlib/authdaemonrc
authmodulelist="authmysql"
authmodulelistorig="authmysql"
DEBUG_LOGIN=2
[root@localhost courier-authlib-0.63.0]#vi /usr/local/authlib/etc/authlib/authmysqlrc
MYSQL_SERVER? localhost
MYSQL_USERNAME? postfix
MYSQL_PASSWORD? postfix
MYSQL_DATABASE? postfix
MYSQL_SOCKET? ?/tmp/mysql.sock--enable-thread-safe-client
MYSQL_USER_TABLE ?mailbox
MYSQL_CRYPT_PWFIELD? password
DEFAULT_DOMAIN? gcp.com
MYSQL_UID_FIELD? '1001'
MYSQL_GID_FIELD? '1001'
MYSQL_LOGIN_FIELD? username
MYSQL_HOME_FIELD? '/var/mailbox/'
MYSQL_NAME_FIELD? name
MYSQL_MAILDIR_FIELD? maildir
MYSQL_QUOTA_FIELD? concat(quota,’S’)
MYSQL_WHERE_CLAUSE? active='1'
?
[root@localhost courier-authlib-0.63.0]# cp courier-authlib.sysvinit /etc/rc.d/init.d/courier-authlib
[root@localhost courier-authlib-0.63.0]# chmod 755 /etc/rc.d/init.d/courier-authlib
[root@localhost courier-authlib-0.63.0]# chkconfig --add courier-authlib
[root@localhost courier-authlib-0.63.0]# chkconfig courier-authlib on
[root@localhost courier-authlib-0.63.0]# service courier-authlib start
[root@localhost courier-authlib-0.63.0]# echo ?"/usr/local/authlib/lib/courier-authlib">>/etc/ld.so.conf
[root@localhost courier-authlib-0.63.0]# ldconfig
[root@localhost courier-authlib-0.63.0]#chmod +x ?/usr/local/authlib/var/spool/authdaemon
[root@localhost courier-authlib-0.63.0]# /usr/local/authlib/sbin/authdaemond? start
[root@localhost courier-authlib-0.63.0]# ln -s /usr/local/authlib/bin/courierauthconfig /usr/bin/courierauthconfig
?
?
2、SASL安裝和配置. (用于實現身份驗證的smtp服務器)
（1）安裝
[root@localhost ~]# rpm -qa|grep cyrus-sasl
[root@localhost ~]# rpm -qa|grep cyrus-sasl |xargs rpm -e --nodeps
[root@localhost ~]#rm –rf /usr/lib/sasl
[root@localhost ~]#rm –rf /usr/lib/sasl2
[root@localhost cyrus-sasl-2.1.23]# ./configure? --disable-anon -enable-plain --enable-login? --enable-sql --with-mysql=/usr/local/mysql? --with-mysql-includes=/usr/local/mysql/include/mysql? --with-mysql-libs=/usr/local/mysql/lib/mysql? --with-authdaemond
[root@localhost cyrus-sasl-2.1.23]#make && make install
[root@localhost cyrus-sasl-2.1.23]# mkdir -pv /var/state/saslauthd?????
[root@localhost cyrus-sasl-2.1.23]# /usr/local/sbin/saslauthd -a shadow pam
[root@localhost cyrus-sasl-2.1.23]# /usr/local/sbin/testsaslauthd -u root -p 用戶密碼 如果提示OK "Success."，則成功
http://blog.csdn.net/longhui2012/archive/2009/08/07/4422709.aspx
[root@localhost cyrus-sasl-2.1.23]# ln -s /usr/local/lib/sasl2 /usr/lib/sasl2
配置庫文件搜索路徑
[root@localhost cyrus-sasl-2.1.23]# echo "/usr/local/lib" >> /etc/ld.so.conf
[root@localhost cyrus-sasl-2.1.23]# ldconfig
[root@localhost cyrus-sasl-2.1.23]# ldconfig –V
[root@localhost cyrus-sasl-2.1.23]# vi /usr/local/lib/sasl2/smtpd.conf
? ?pwcheck_method: authdaemond
?? mech_list: PLAIN LOGIN
?? log_level: 3
?? authdaemond_path: /usr/local/authlib/var/spool/authdaemon/socket
七、postfixadmin安裝和配置
所以用2.1.0是因為有DATABASE_MYSQL.TXT文件,但它卻沒有增加郵件目錄和刪除目錄的腳本，postfixadmin-2.3.2.tar.gz中卻提供腳本
[root@localhost ]#tar zxvf? postfixadmin-2.1.0.tar.gz
[root@localhost ]# cp -r /root/postfixadmin-2.1.0 /var/www/postfixadmin
[root@localhost ~]# vim /usr/local/apache2/conf/httpd.conf
Alias /postfixadmin /var/www/postfixadmin
<Directory /var/www/postfixadmin>
???? Options Indexes FollowSymLinks
???? AllowOverride None
???? Order allow,deny
???? Allow from all
</Directory>
?
[root@localhost ]#mysql -u root 1 < /var/www/postfixadmin/DATABASE_MYSQL.TXT
[root@localhost ]#chown -R vmail:vmail /var/www/postfixadmin
[root@localhost ]#vim /var/www/postfixadmin/config.inc.php
$CONF['default_language'] = 'cn';
[root@localhost ~]# vim? /var/www/postfixadmin/admin/create-mailbox.php
??? $tQuota = $CONF['maxquota'];
233???? system("sudo /usr/local/bin/maildirmake.sh $fDomain ".$_POST['fUsername']);
[root@localhost ~]# vim? /var/www/postfixadmin/admin/delete.php
$result = db_query ("SELECT * FROM mailbox WHERE username='$fDelete' AND domain='$fDomain'");
????? $userarray=explode("@",$fDelete);
???? ?$user=$userarray[0];
????? $domain=$userarray[1];
????? system("sudo /usr/sbin/maildirdel.sh $domain $user");
注意/var/www/postfixadmin目錄下create-mailbox.php，delete.php作同樣的修改
?
八、Postfix安裝和配置
[root@localhost postfix-2.6.5]# groupadd -g 12345 postfix
[root@localhost postfix-2.6.5]#groupadd -g 54321 postdrop
[root@localhost postfix-2.6.5]# make -f Makefile.init makefiles 'CCARGS=-DHAS_MYSQL -I/usr/local/mysql/include/mysql -DUSE_SASL_AUTH ?-DUSE_CYRUS_SASL ?-I/usr/ \
local/include/sasl' 'AUXLIBS=-L/usr/local/mysql/lib/mysql -lmysqlclient -lz -lm -L/usr/local/lib -lsasl2'
[root@localhost postfix-2.6.5]#make -f Makefile.in MAKELEVEL= Makefiles
(echo "# Do not edit -- this file documents how Postfix was built for your machine."; /bin/sh makedefs) >makedefs.tmp
No <db.h> include file found.
Install the appropriate db*-devel package first.
See the RELEASE_NOTES file for more information.
make: *** [Makefiles] 錯誤 1
make: *** [makefiles] 錯誤 2
下載地址
http://www.oracle.com/technology/global/cn/software/products/berkeley-db/db/index.html
tar –zxvpf db-4.8.26.tar.gz
cd db-4.8.26
cd build_unix
../dist/configure
make &&make install
解決方法(同上實驗一樣)：安裝 db*-devel 包 db4-4.3.29-10.el5.i386.rpm
http://rpm.pbone.net/index.php3/stat/4/idpl/13943838/dir/centos_5/com/db4-4.3.29-10.el5.i386.rpm.html
?
重新編譯
[root@localhost postfix-2.6.5]#make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/local/mysql/include/mysql -DUSE_SASL_AUTH ?-DUSE_CYRUS_SASL -I/usr/ \

九、Corurier-imap安裝和配置
編譯出錯??? configure: error: courierauthconfig not found
解決方法：設置變量COURIERAUTHCONFI
[root@localhost courier-imap-4.5.0]# export COURIERAUTHCONFIG=/usr/local/authlib/bin/courierauthconfig
然后重新執行編譯，還是不行出現configure: error: This option is no longer supported
版本問題:courier-imap-4.8.0.20100628.tar.bz2不行，換成如下版本則可以courier-imap-4.5.0.tar.bz2
[root@localhost courier-imap-4.5.0]# ./configure --prefix=/usr/local/imap --with-redhat --disable-root-check? --enable-unicode=utf-8,gb2312,gbk --with-trashquota? --with-dirsync --with-mysql-libs=/usr/local/mysql/lib/mysql --with-mysql-includes=/usr/local/mysql/include/mysql/ --with-authmysql --with-authmysql=yes

[root@localhost courier-imap-4.5.0]# make && make install
[root@localhost courier-imap-4.5.0]#make install-configure
[root@localhost courier-imap-4.5.0]# make install-configure

[root@localhost ~]# echo " /usr/local/imap/sbin/imapd? start">> /etc/rc.d/rc.local
?
十、courier-maildrop 安裝和配置
Maiidrop的作用是本地投遞，即把收到的郵件移動到相應的用戶目錄。它是安裝maildrop所必須的，所以需要先安裝這個軟件（如果系統不存在這個軟件的話）。
安裝 Unzip pcre-8.10.zip
[root@localhost pcre-8.10]# ./configure
[root@localhost pcre-8.10]# Make&& make istall
安裝maildrop
[root@localhost maildrop-2.5.0.20100815]# ./configure? --prefix=/usr/local/maildrop --enable-sendmail=/usr/sbin/sendmail --enable-trusted-users='root vmail'? --enable-syslog=1? --enable-maildirquota? --enable-maildrop-uid=1001? --enable-maildrop-gid=1001? --with-trashquota --with-dirsync
courierauthdebug.h: 沒有那個文件或目錄
解決方法：編譯時加CPPFLAGS='-I/usr/local/courier-authlib/include'
[root@localhost maildrop-2.5.0.20100815]# Make&& make istall
[root@localhost maildrop-2.5.0.20100815]# cp /usr/local/maildrop/bin/maildrop /usr/bin
[root@localhost maildrop-2.5.0.20100815]# maildrop –v
maildrop 2.5.0 Copyright 1998-2005 Double Precision, Inc.

[root@localhost ~]# more /etc/maildroprc
logfile "/var/mailbox/maildrop.log"?
to "$HOME/$DEFAULT
[root@localhost maildrop-2.5.0.20100815]# /usr/local/imap/sbin/imapd start
[root@localhost postfix-2.6.5]# telnet 192.168.1.1.117 25
192.168.1.1.117/25: Temporary failure in name resolution
解決方法:修改/etc/resolv.conf文件
maidrop沒有創建和刪除郵件用戶目錄的能力，在配置postfixadmin時，我們提到需要使用2個shell腳本 /usr/sbin/maildirdel.sh及/usr/local/bin/maildirmake.sh,這2個腳本的作用就是用來彌補maildrop不能創建/刪除目錄這個缺陷的。
[root@localhost extmail]# more /usr/local/bin/maildirmake.sh
#!/bin/sh
# Auto create maildir under FreeBSD
# Author: He zhiqiang <hzqbbc@hzqbbc.com>
# copyright (c) 1998-2005
BASE="/var/mailbox"
umask 077
# mkdir -p to omit error
mkdir -p "$BASE/$1"
# step into the new dir and call maildirmake
/usr/local/bin/maildirmake "$BASE/$1/$2"
?
[root@localhost extmail]# more /usr/sbin/maildirdel.sh
#!/bin/bash
rm -rf /var/mailbox/$1/$2
?
[root@localhost extmail]#chmod +x /usr/local/bin/maildirmake.sh
[root@localhost extmail]#chmod +x /usr/sbin/maildirdel.sh
這2個腳本由web調用，而web（apache）的執行用戶為vmail,出于安全考慮，我們給vmail用戶的權限非常有限，為了保證這2個 shell腳本能正常執行使用vi這樣的編輯器來修改/etc/sudoers這個配置文件，把行"vmail ALL = NOPASSWD: /usr/local/bin/maildirmake.sh, /usr/sbin/maildirdel.sh"追加到文件末尾即可！
##/etc/sudoers里需要把 "Defaults??? requiretty"這行注釋掉式//
# Example script for removing a Maildir from a Courier-IMAP virtual mail
# hierarchy.
?
# The script looks at arguments 1 and 2, assuming that they
# indicate username and domain, respectively.
?
# The script will not actually delete the maildir. I moves it
# to a special directory which may once in a while be cleaned up
# by the system administrator.
?
# This script should be run as the user which owns the maildirs. If
# the script is actually run by the apache user (e.g. through PHP),
# then you could use "sudo" to grant apache the rights to run
# this script as the relevant user.
# Assume this script has been saved as
# /usr/local/bin/postfixadmin-mailbox-postdeletion.sh and has been
# made executable. Now, an example /etc/sudoers line:
# apache ALL=(courier) NOPASSWD: /usr/local/bin/postfixadmin-mailbox-postdeletion.sh
# The line states that the apache user may run the script as the
# user "courier" without providing a password.
十一、Extmail安裝和配置
[root@localhost ~]# tar zxvf extmail-1[1][1].1.1.tar.gz -C /var/www
[root@localhost ~]# mv /var/www/extmail-1.1.1 /var/www/extsuite/extmail
[root@localhost ~]#cd /var/www/extsuite/extmail
[root@localhost ~]# chown -R postfix:postfix? /var/www/extsuite/extmail/cgi/
[root@localhost extmail]# cp webmail.cf.default webmail.cf
[root@localhost extmail]#vim webmail.cf
SYS_MAILDIR_BASE =/var/mailbox?? //虛擬用戶mail存放的根目錄
SYS_MYSQL_HOST = localhost
SYS_MYSQL_USER = postfix
SYS_MYSQL_PASS = postfix
SYS_MYSQL_DB = postfix
SYS_MYSQL_SOCKET =/tmp/mysql.sock--enable-thread-safe-client
SYS_AUTHLIB_SOCKET = /usr/local/authlib/var/spool/authdaemon/socket
[root@localhost ~]# vim /usr/local/apache2/conf/httpd.conf
ScriptAlias /extmail/cgi/?? /var/www/extsuite/extmail/cgi/
<Directory "/var/www/extsuite/extmail/cgi">
??? AllowOverride None
??? Options None
??? Order allow,deny
??? Allow from all
</Directory>
Alias /extmail /var/www/extsuite/extmail/html
<Directory "/var/www/extsuite/extmail/cgi/html">
??? AllowOverride None
??? Options None
??? Order allow,deny
?? ?Allow from all
</Directory>
在文件/var/www/extsuite/extmail/html/default/index.html 加入下面的標識，可以得到不同郵件域的下拉列表????? ??????
<TD><%domain%></TD>
??? <TD>
???????? <select name="domain" size="1" class="input_select"></option>
??????????? <option value="gcp.com">gcp.com</option>
??????????? <option value="mail.gcp.com">mail.gcp.com</option>
???????? </select>
??? </TD>
?
