POSTFIX 邮件系统

本文介绍Postfix邮件系统的安装与配置. 如有疑问可以留言.

本文主要内容是poftfix+mysql 实现虚拟用户.

http://wiki.extmail.org/extmail_solution_for_linux_centos-5

平台:

Centos 5.6 64位

所需软件:

Apache:2.2.15
Mysql:5.1.36
Php:5.2.13
Postfix:2.8.0
Courier-authlib:0.63
Cyrus-sasl:2.1.22
BerkeleyDB:4.5.20
Courier-IMAP:4.9.3
Maildrop:2.5.4
Extman:1.1
Extmail:1.2
Rrdtool:1.4.3
Slockd:0.99

先安装 Apache,Mysql,Php

Mysql 虚拟用户使用.

Apache ,php ,Mysql extmail Web管理台需要.

Apache,Mysql,Php的安装这里不做介绍,它们的安装文档网上很多,本人blog也有安装文档.

这里只介绍下Apache,Mysql,Php的编译参数.

Apache编译参数: (关于suexec可以看下http://lamp.linux.gov.cn/Apache/ApacheMenu/suexec.html)

./configure --prefix=/usr/local/apache2.2.15 --with-mpm=worker --enable-so --enable-rewrite --enable-headers --enable-expires --enable-suexec --with-suexec-caller=nobody --with-suexec-docroot=/opt/www

Mysql编译参数:

#./configure --prefix=/usr/local/mysql --datadir=/opt/mydata --with-charset=utf8 --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-ssl --with-embedded-server --enable-local-infile --enable-assembler --with-plugins=innobase --with-plugins=partition

php编译参数:

#./configure --prefix=/usr/local/php-5.2.13   --with-config-file-path=/usr/local/php-5.2.13 --with-apxs2=/usr/local/apache2.2.15/bin/apxs --with-bz2 --with-curl --with-curlwrappers --enable-ftp  --enable-sockets --disable-ipv6 --with-gd --with-jpeg-dir=/usr/local --with-png-dir=/usr/local --with-freetype-dir=/usr/local --enable-gd-native-ttf --with-iconv-dir=/usr/local --enable-mbstring --enable-calendar --with-gettext --with-libxml-dir=/usr/local  --with-zlib --enable-zend-multibyte --with-pdo-mysql=/usr/local/mysql  --with-mysqli=/usr/local/mysql/bin/mysql_config --with-mysql=/usr/local/mysql

说明:

/usr/local/src/tarbag/    \\源码包存放的位置
/usr/local/src/software/   \\源码包解压出来存放的位置

以下安装建立在以上所需条件.所有安装为源码安装,源码包放在tarbag目录下,解压后放在software目录下:

首先安装courier-authlib
下载地址:http://prdownloads.sourceforge.net/courier

#cd /usr/local/src/tarbag
#wget http://sourceforge.net/projects/courier/files/authlib/0.63.0/courier-authlib-0.63.0.tar.bz2/download
#tar jvxf courier-authlib-0.63.tar.bz2 -C ../software/
安装之前添加postfix和maildrop相关的用户&用户组
#groupadd postfix -g 1000
#groupadd postdrop -g 1002
#useradd postfix -u 1000 -g postfix -G postdrop
#groupadd vmail -g 1001
#useradd vmail -u 1001 -g 1001
#./configure    --prefix=/usr/local/courier-authlib --with-mailuser=vmail --with-mailgroup=vmail   --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=x86-64 -O2 -fexpensive-optimizations" CXXFLAGS="-march=x86-64 -O2 -fexpensive-optimizations"
#make
#make install

1.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

2.投递过程出现如下错误:

May 30 16:08:27 hsf postfix/pipe[25422]: D822E210104: to=<microsea@hsf.com>, relay=maildrop, delay=1248, status=deferred (temporary failure. Command output: ERR: authdaemon: s_connect() failed: Permission denied /usr/local/bin/maildrop: Temporary authentication failure. )

说明编译authlib时没有指定maildrop的用户和组,加上--with-mailuser和--with-mailgroup 指定用户和组后重编译安装.

增加"/usr/local/courier-authlib/lib/courier-authlib"到"/etc/ld.so.conf"，并执行ldconfig命令。
#echo  "/usr/local/courier-authlib/lib/courier-authlib" >> /etc/ld.so.conf
#ldconfig -v 
#cp /etc/authdaemonrc.dist  /etc/authdaemonrc
#vi /etc/authdaemonrc  
authmodulelist="authmysql"
authmodulelistorig="authmysql"
daemons=5
authdaemonvar=/usr/local/courier-authlib/var/spool/authdaemon
DEBUG_LOGIN=0
DEFAULTOPTIONS=""
LOGGEROPTS=""
#vi /etc/authmysqlrc
MYSQL_SERVER            localhost
MYSQL_USERNAME          extmail
MYSQL_PASSWORD          extmail
MYSQL_SOCKET           /tmp/mysql.sock
MYSQL_PORT              3306
MYSQL_OPT               0
MYSQL_DATABASE          extmail
MYSQL_USER_TABLE        mailbox
MYSQL_CRYPT_PWFIELD     password
MYSQL_UID_FIELD         '1001'
MYSQL_GID_FIELD         '1001'
MYSQL_LOGIN_FIELD       username
MYSQL_HOME_FIELD        concat('/opt/mailbox/',homedir)
MYSQL_NAME_FIELD        name
MYSQL_MAILDIR_FIELD     concat('/opt/mailbox/',maildir)

启动courier-authlib

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

安装 cyrus-sasl:

安装 cyrun-sasl 先把系统自带的给卸载了.

#rpm -e `rpm -qa | grep sasl`

如果卸载不掉加上 --nodeps --allmatches选项强制卸载

下载地址:

ftp://ftp.andrew.cmu.edu/pub/cyrus-mail/

#wget ftp://ftp.andrew.cmu.edu/pub/cyrus-mail/cyrus-sasl-2.1.22.tar.gz
安装时最新版本2.1.22
#tar zxvf cyrus-sasl-2.1.22.tar.gz  -C ../software/
#cd ../software/cyrus-sasl-2.1.22/
#./configure --prefix=/usr/local/sasl2 --with-mysql=/usr/local/mysql --disable-sample --disable-saslauthd --disable-pwcheck --disable-cram --disable-digest --disable-krb4 --disable-gssapi --disable-anon --enable-plain --enable-login --enable-sql --disable-ntlm --disable-otp --disable-srp --disable-srp-setpass --with-authdaemond=/usr/local/courier-authlib/var/spool/authdaemon/socket --with-mysql-includes=/usr/local/mysql/include/ --with-mysql-libs=/usr/local/mysql/lib/mysql
#make
#make install
#ln -s /usr/local/sasl2/lib/sasl2 /usr/lib/  //这步一定要做..以下步骤做了以后Postfix还是找不到正确的sasl 所以会报验证错误的信息.  

添加以下两行:
/usr/local/sasl2/lib/sasl2
/usr/local/sasl2/lib
到"/etc/ld.so.conf"，并执行ldconfig命令.
#vi /usr/local/sasl2/lib/sasl2/smtpd.conf    //这个文件是自己创建的
pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket  //这个目录与编译时候--with-authdaemond 选项目录相同

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

创建运行时需要的目录并调试启动

# mkdir -pv /var/state/saslauthd      
# /usr/local/sasl2/sbin/saslauthd  -a  shadow  pam  -d

如果没有报错.crtl+c结束掉进程 .

启动并测试

# /usr/local/sasl2/sbin/saslauthd -a shadow pam
# /usr/local/sasl2/sbin/testsaslauthd -u root -p root用户密码

开机自动启动

# echo "/usr/local/sasl2/sbin/saslauthd -a shadow pam">>/etc/rc.local

安装BerkeleyDB
卸载系统自带的DB4

#tar zxvf db-4.5.20.tar.gz
#cd db-4.5.20/build_unix
#../dist/configure --prefix=/usr/local/BerkeleyDB
#make
#make install

修改相应的头文件指向

# mv  /usr/include/db4  /usr/inculde/db4.OFF
# rm  /usr/include/db_cxx.h
# rm  /usr/include/db.h
# rm  /usr/include/db_185.h
# ln -sv /usr/local/BerkeleyDB/include  /usr/include/db4
# ln -sv /usr/local/BerkeleyDB/include/db.h  /usr/include/db.h
# ln -sv /usr/local/BerkeleyDB/include/db_cxx.h  /usr/include/db_cxx.h

配置库文件搜索路径

# echo "/usr/local/BerkeleyDB/lib" >> /etc/ld.so.conf
# ldconfig –v

安装postfix

关闭redhat 系统自带的sendmail

#chkconfig --level 2345 sendmail off

下载地址:

http://www.postfix.org

#wget ftp://ftp.cuhk.edu.hk/pub/packages/mail-server/postfix/official/postfix-2.8.0.tar.gz

下载VDA补丁,使postfix支持磁盘限额

#wget http://vda.sourceforge.net/VDA/postfix-vda-2.8.0.patch

postfix版本:2.8.0,VDA也要下载相应版本补丁.

#tar xvzf postfix-2.8.0.tar.gz -C ../software
#mv postfix-vda-2.8.0.patch ../software/postfix-2.8.0/
#cd ../software/postfix-2.8.0/
#make clean
#make tidy
#patch -p1 < postfix-vda-2.8.0.patch 
#make -f Makefile.init Makefiles 'CCARGS=-DHAS_MYSQL -I/usr/local/mysql/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/local/sasl2/include/sasl' 'AUXLIBS=-L/usr/local/mysql/lib/mysql -lmysqlclient -lz -lm -L/usr/local/sasl2/lib   -lsasl2 -L/usr/local/BerkeleyDB/lib'
#make
#make install
执行“make install”命令后，期间会需要设置如下一些安装参数，一般都使用默认设置（按回车），如果有特殊需要，直接在后面输入自己的设置，回车即可。
install_root: [/]                    //指定系统的根目录
tempdir: [/usr/local/src/software/postfix-2.8.0/]   //指定postfix-install脚本使用的临时文件目录
config_directory: [/etc/postfix]       //设置Postfix的配置文件目录
daemon_directory: [/usr/libexec/postfix]
command_directory: [/usr/sbin]      //设置Postfix命令的存放目录
queue_directory: [/var/spool/postfix] //设置邮件队列目录
sendmail_path: [/usr/sbin/sendmail]
newaliases_path: [/usr/bin/newaliases]
mailq_path: [/usr/bin/mailq]
mail_owner: [postfix]
setgid_group: [postdrop]
html_directory: [no]
manpage_directory: [/usr/local/man]
readme_directory: [no]

下面是我的配置目录:

配置文件目录：/etc/postfix/

服务程序目录：/usr/local/postfix/libexec/

邮件队列目录：/var/spool/postfix/

邮件管理程序目录：/usr/local/postfix/sbin/

日志文件目录: /var/log/maillog

#mv /etc/aliases /etc/aliases.old
#ln -s /etc/postfix/aliases /etc/aliases

最后 :

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：

#/usr/bin/newaliases

如果编译时候没有加-L/usr/local/BerkeleyDB/lib newaliases会去找系统自带的4.3.29的库.会报错.

检验postfix是否支持sasl认证，如果输出为以下结果，则支持：

#/usr/local/postfix/sbin/postconf   -a
cyrus
dovecot
#/usr/local/postfix/sbin/postconf -m | grep mysql
mysql

没有的话需重新编译 postfix 。如果postconf -a 没有 cyrus 的话注意看下 postfix 编译的关于 cyrus-sasl 的参数有没正确 . 再看下 cyrus-sasl 安装好了没有 .

下面添加生成Mysql验证的一些配置文件:

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

修改postfix配置文件:

启动和停止postfix服务:
#/usr/local/postfix/sbin/postfix start
#/usr/local/postfix/sbin/postfix stop

安装Courier-IMAP

下载地址:

http://prdownloads.sourceforge.net/courier

目前最新版4.9.3

#wget http://sourceforge.net/projects/courier/files/imap/4.9.3/courier-imap-4.9.3.tar.bz2/download
#tar jvxf courier-imap-4.9.3.tar.bz2 -C ../software/
#cd ../software/courier-imap-4.9.3/
#./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.
没有加COURIERAUTHCONFIG='/usr/local/courier-authlib/bin/courierauthconfig'会出现:
checking for courierauthconfig... no
configure: WARNING: === Courier authentication library not found.
configure: WARNING: === You need to download and install
configure: WARNING: === http://www.courier-mta.org/download.php#authlib first.

configure: WARNING:
configure: error: courierauthconfig not found
解决方法
#export    COURIERAUTHCONFIG=/usr/local/courier-authlib/bin/courierauthconfig
再执行configure.命令
#make
#make install
建立配置文件
#cd /usr/local/courier-imap/etc
#ls *.dist | awk -F"." '{print "cp "$0" "$1""}' | sh
打开pop3,imapd支持，修改MAILPATH
#vi /usr/local/courier-imap/etc/pop3d

安装maildrop

下载地址:http://sourceforge.net/projects/courier/files/maildrop/

目前最新版本:2.5.4

http://sourceforge.net/projects/courier/files/maildrop/2.5.4/maildrop-2.5.4.tar.bz2/download

将courier-authlib的头文件及库文件链接至/usr目录(编译maildrop时会到此目录下找此些相关的文件):

# ln -sv /usr/local/courier-authlib/bin/courierauthconfig   /usr/bin
# ln -sv /usr/local/courier-authlib/include/*   /usr/include

1、 maildrop 需要 pcre 的支持，因此，接下来将首先安装 pcre

#tar zxvf pcre-7.9.tar.gz  -C ../software/
# cd ../software/pcre-7.9/
# ./configure
# make 
# make check
# make install
# tar jxvf maildrop-2.5.4.tar.bz2  -C ../software/
#cd ../software/maildrop-2.5.4/
# cd maildrop-2.5.4
# ./configure --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
# make
# make install

检查安装结果，请确保有"Courier Authentication Library extension enabled."一句出现：

# maildrop -v
maildrop 2.5.4 Copyright 1998-2005 Double Precision, Inc.  ///注意看下这个版本是不是2.5.4是否是现在安装的.如果不是的话可能就是系统自带的.要把系统自带的卸载了再安装一遍.或者把/usr/local/bin/maildrop删了.再安装一遍也可以 .
GDBM extensions enabled.
Courier Authentication Library extension enabled.
Maildir quota extension enabled.
This program is distributed under the terms of the GNU General Public
License. See COPYING for additional information.

2、新建其配置文件/etc/maildroprc文件，首先指定maildrop的日志记录位置：

# vi /etc/maildroprc
添加：
logfile "/var/log/maildrop.log" 
# touch /var/log/maildrop.log
# chown vmail.vmail /var/log/maildrop.log

3 、配置 Postfix

编辑master.cf

# vi /etc/postfix/master.cf
启用如下两行
maildrop  unix  -       n       n       -       -       pipe
   flags=DRhu user=vmail argv=/usr/local/bin/maildrop -d ${recipient} //注意：定义transport的时候，即如上两行中的第二行，其参数行必须以空格开头，否则会出错。

编辑main.cf

# vi /etc/postfix/main.cf
virtual_transport = maildrop
virtual_uid_maps = static:1001
virtual_gid_maps = static:1001

4 、编辑 /etc/authmysqlrc

# vi /etc/authmysqrc
MYSQL_UID_FIELD  '1001'
MYSQL_GID_FIELD  '1001'

5 、编辑 /etc/httpd/httpd.conf ，修改运行用户 :

如果启用了suexec的功能，则将虚拟主机中指定的

SuexecUserGroup vmail vmail

如果没有使用上面的功能，则修改User和Group指令后的用户为vmail

将前文中的如下项

User postfix
Group postfix

修改为：

User vmail
Group vmail

6 、将用户邮件所在的目录/opt/mailbox和 extman 的临时目录 /tmp/extman 的属主和属组指定为 vmail

#mkdir /tmp/extman
#chown -R vmail.vmail /opt/mailbox
#chown -R vmail.vmail /tmp/extman

安装extman

#tar zxvf extman-1.1.tar.gz  -C ../software/
#mv ../software/extman-1.1/ /opt/www/extman
#cd /opt/www/extman/
#chown -R vmail.vmail /opt/www/extman

#/usr/local/apache2.2.15/bin/apachectl -t
#/usr/local/apache2.2.15/bin/apachectl -k restart

安装slock ,extman需要启动一个服务所需的.

#cd /usr/local/src/tarbag
#tar zxvf slockd-0.99.tar.gz  -C ../software/
#cd ../software/slockd/
#mv slockd/ /usr/local/
#/usr/local/slockd/slockd-init start
#cd /var/run/
#mkdir extmail 
#/opt/www/extman/daemon/cmdserver -v -d
#cd /opt/www/extman/addon
#cp -r mailgraph_ext/ /usr/local/
#/usr/local/mailgraph_ext/mailgraph-init start 
如果报这个错:Can’t locate RRDs.pm in @INC 
解决办法:
# cp -rp /usr/local/rrdtool/lib/perl/5.8.8/x86_64-linux-thread-multi/* /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/
如果报这个错:Can't locate File/Tail.pm in @INC
解决方法为:
#cpan
cpan>install File::Tail
cpan>quit

导入数据库

#cd /opt/www/extman/docs
# /usr/local/mysql/bin/mysql -u root -p < extmail.sql   
Enter password:   
# /usr/local/mysql/bin/mysql -u root -p < init.sql   
Enter password:

extman默认管理帐号为：root@extmail.org 密码为：extmail*123*
重启下apache

#/usr/local/apache2.2.15/bin/apachectl -k restart

启动后访问extman如果验证码出不来是一个perl的GD库没有装

#cd /usr/local/src/tarbag/
#tar zxvf GD-2.35.tar.gz  -C ../software
#perl Makefile.PL
#make
#make install

图形日志没有显示 .是因为rrdtool没有装

#cd /usr/local/src/tarbag/
#tar xvf rrdtool-1.4.3.tar.gz -C ../software/
#cd ../software/rrdtool-1.4.3/
#./configure --prefix=/usr/local/rrdtool
#make
#make install

访问extmail FAQ:

Can't locate DBI.pm in @INC     错误,用yum 安装下perl-DBI.x86_64 模块就好.
Can't locate DBD/mysql.pm       错误,用yum 安装下perl-DBD-MySQL.x86_64 模块.
如果yum无法安装可以去下载DBD-mysql-3.0007 源码包.编译方法如下:
perl Makefile.PL --libs="-L/usr/local/mysql/lib/mysql/ -lmysqlclient -lz" --cflags=-I/usr/local/mysql/include/mysql/
make 
make install

Unix::Syslog not found,.        错误,安装Unix-Syslog模块.

至此,postfix安装完成. 后续增加反垃圾,防病毒功能.

解决方法：

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

问题二:

Sep 24 18:05:05 extmail postfix/smtpd[4510]: warning: SASL authentication failure: cannot connect to Courier authdaemond: Permission denied
Sep 24 18:05:05 extmail postfix/smtpd[4510]: warning: extmail[127.0.0.1]: SASL login authentication failed: generic failure

是权限的问题.
Authdaemon_path 的权限 .还有他的父目录权限.
最后看下开机需要运行的服务可以写在/etc/rc.local里面:

#cat /etc/rc.local
/usr/local/apache2.2.14/bin/apachectl -k start
/usr/local/sasl2/sbin/saslauthd -a shadow pam
/usr/local/postfix/sbin/postfix start
/opt/www/extman/daemon/cmdserver -d
/usr/local/slockd/slockd-init start
/usr/local/mailgraph_ext/mailgraph-init start
/usr/local/courier-authlib/sbin/authdaemond start
/opt/www/extmail/dispatch-init start  
service imapd start
service mysqld start
