二.邮件发送接收相关包的安装
再继续安装前先清理一下系统自带的一些软件
Sendmail相关包rpm –q sendmail
sendmail-8.13.8-2.el5
----------------------------------------------
清除：
rpm -e sendmail --nodeps
Sasl 相关包列出 rpm -qa|grep sasl
cyrus-sasl-2.1.22-4
cyrus-sasl-devel-2.1.22-4
cyrus-sasl-plain-2.1.22-4

ln -s /usr/src/kernels/2.6.18-128.el5-i686 /usr/src/linux //避免以下安装编译出现问题
一．安装courier-authlib
安装过程：
……………………………安装开始………………………………………………
Shell> tar jxvf courier-authlib-0.62.2.tar.bz2
Shell> cd courier-authlib-0.62.2
Shell>./configure
--with-mailuser=vmail --with-mailgroup=vmail
--with-mysql-libs=/usr/local/mysql/lib/mysql
--with-mysql-includes=/usr/local/mysql/include/mysql
--prefix=/usr/local/authlib
--without-stdheaderdir
Shell> make && make install
Shell> make install-configure
…………………………安装结束……………………………………………
---------------------------------------------------------
一般情况下，anthlib的安装应该是容易完成的。
配置：
配置authlib.在目录/usr/local/authlib/etc/authlib中，修改文件authdaemonrc及authmysqlrc。
vim /usr/local/authlib/etc/authlib/authdaemonrc
| vi /usr/local/authlib/etc/authlib/authdaemonrc
修改上面3项，其他的项保持不变。这个修改前2行表示用mysql认证模块；把DEBUG_LOGIN的值有默认的“0”改成“2”的用意是运行postfix时有更多的信息输出，通过生成的日志以帮助排错。 |
| vi /usr/local/authlib/etc/authlib/authmysqlrc MYSQL_DATABASE extmail MYSQL_SOCKET /usr/local/mysql/tmp/mysql.sock MYSQL_PORT 3306 DEFAULT_DOMAIN mail.test.com MYSQL_LOGIN_FIELD username MYSQL_NAME_FIELD name 特别注意MYSQL_UID_FIELD和MYSQL_GID_FIELD字段的值，这里是‘1001’,也可以是其它的，但一定要与vmail用户及组相一致（id vmail可以得出这2者的值） |
后续工作还有，所以现在还不能测试。
-------------------------------------------------------
二．安装SASL
cyrus-sasl-2.1.22.tar.gz
安装过程：
……………………………安装开始………………………………………………
Shell> tar zxvf cyrus-sasl-2.1.22.tar.gz
Shell> cd cyrus-sasl-2.1.22
Shell> ./configure --disable-anon
--disable-gssapi //授权
--disable-sample
--disable-digest //授权
--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=/usr/local/authlib/var/spool/authdaemon/socket
Shell> make
Shell> make install
…………………………安装结束……………………………………………
配置：
ln -s /usr/local/lib/sasl2 /usr/lib/sasl2 //sasl的安装目录是/usr/local/lib/sasl //安装结束后有Warning警告
echo “/usr/local/lib” >> ld.so.conf //否则postfix 编译里会找不到libsasl2.so.2
创建文件 /usr/local/lib/sasl2/smtpd.conf,并加入如下内容：
| pwcheck_method: authdaemond mech_list: PLAIN LOGIN log_level: 3 authdaemond_path: /usr/local/authlib/var/spool/authdaemon/socket |
Sasl2需要使用文件/usr/local/authlib/var/spool/authdaemon/socket，但默认情况下，其属性是744，需要把它加上执行权限，以便文件属组（主）而外的其它用户可以执行。运行命令
chmod +x /usr/local/authlib/var/spool/authdaemon即可，如果不这样处理，smtp验证无一例外会失败的。
创建运行时需要的目录并调试启动
# mkdir -pv /var/state/saslauthd
# /usr/local/sbin/saslauthd -v //看看版本是不是2.1.22
saslauthd 2.1.22
authentication mechanisms: getpwent pam rimap shadow
# /usr/local/sbin/saslauthd -a shadow pam -d //正常不会报错
启动并测试
# /usr/local/sbin/saslauthd -a shadow pam
# /usr/local/sbin/testsaslauthd -u root -p password //正常显示0: OK "Success"成功
(Password改成机器登录账号root 的密码,这里不是账号不是指的MySQL账号密码。否则会提示：
0: NO "authentication failed",同时，注意这里测试不用开启authdaemond(authlib)
加入开机自启动
Echo “/usr/local/sbin/saslauthd -a shadow pam” >>/etc/rc.local
三．安装postfix
Make参数参考：安装源文件READ_FILES目录
# more README_FILES/MYSQL_README
安装过程：
……………………………安装开始………………………………………………
Shell> tar zxvf postfix-2.5.6.tar.gz
Shell> cd postfix-2.5.6
Shell> make 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'
@@注意：1. 如果没有Makefile文件，需要设置成make -f Makefile.init
2. /usr/local/mysql/include 如果此目录下还有mysql目录，应改成/usr/local/mysql/include/mysql
3. /usr/local/mysql/lib 如果此目录下还有mysql目录，应改成/usr/local/mysql/lib/mysql
如果没有意外，make这一步很快就执行完了，接下来就是安装，使用的命令是
Shell> make install
程序先自动执行一阵子，然后会进入交互状态，等待用户的输入，一般情况下，一路回车即可完成所有的安装。
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：
shell> /usr/bin/newaliases
…………………………安装结束……………………………………………
检验postfix是否支持sasl认证，如果输出为以下结果，则支持：
shell> /usr/sbin/postconf -a //postfix 安装没有指定目录
cyrus
dovecot
shell> /usr/sbin/postconf -m |grep mysql
mysql //没有的话需重新编译postfix
四．安装imap
Postfix只是实现邮件系统的smtp功能，pop3或imap则需要另外的软件来实现，这个软件就是courier-imap(当然也有别的软件可以选择)。
……………………………安装开始………………………………………………
Shell> tar jxvf courier-imap-4.4.1.tar.bz2
Shell> cd courier-imap-4.4.1
Shell>./configure
--prefix=/usr/local/imap
--with-RedHat
--disable-root-check
--enable-unicode=utf-8,iso-8859-1,gb2312,gbk,gb18030
--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
CPPFLAGS='-I/usr/local/authlib/include' LDFLAGS='-L/usr/local/authlib/lib/courier-authlib'
COURIERAUTHCONFIG='/usr/local/authlib/bin/courierauthconfig'
[以上时间长一些]
Shell> make
Shell> make install
Shell> make install-configure
……………………………安装结束………………………………………………
配置：
……………………………配置开始………………………………………………
修改配置文件/usr/local/imap/etc/pop3d及/usr/local/imap/etc/imapd。把/usr/local/imap
/etc/pop3d 文件的行“POP3DSTART=NO”改成“POP3DSTART=YES”，再依照这个形式把文件/usr/local/imap/etc/imapd的行“IMAPDSTART=NO”改成“IMAPDSTART=YES”即可。
加入开机启动：
cp courier-imap.sysvinit /etc/rc.d/init.d/imapd // courier-imap.sysvinit在安装源文件中
chmod +x /etc/rc.d/init.d/imapd
chkconfig --add imapd
[chkconfig --level 2345 imapd on]
Service imapd start //输出Starting Courier-IMAP server: imap pop3
检测：
netstat -tnl|egrep "110|143"
五．安装pcre
安装前先卸载系统自带的pcre-6.6-1.1
Rpm –e pcre
自带的pcre RPM包可能与一些有冲突，可以先卸载掉
Shell> rpm –e pcre如果提示libpcre.so.0与别的软件有依存关系。可以这样
先备份一下libpcre.so.0这个文件，然后。
Shell> rpm -e pcre –nodeps
……………………………安装开始………………………………………………
Shell> tar zxvf pcre-7.8.tar.gz
Shell> cd pcre-7.8
Shell> ./configure
Install prefix .................. : /usr/local
C preprocessor .................. : gcc -E

Link pcregrep with libz ......... : no
Link pcregrep with libbz2 ....... : no
Link pcretest with libreadline .. : no
Shell> make
Shell> make install
……………………………安装结束………………………………………………
六．安装maildrop
注意%源码安装的，将courierauthconfig 命令链接到/usr/bin里，假设装在：
/usr/local/authlib/bin/courierauthconfig，则：
ln -s /usr/local/authlib/bin/courierauthconfig /usr/bin/courierauthconfig
这样编译出来的maildrop才会Courier Authentication Library extension enabled.
……………………………安装开始………………………………………………
Shell> tar jxvf maildrop-2.0.4.tar.bz2
Shell> cd maildrop-2.0.4
Shell>./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
Shell> make
Shell> make install
Shell> cp /usr/local/bin/maildrop /usr/bin //可有可无
……………………………安装结束………………………………………………
验证安装是否成功:
Shell> maildrop –v
[root@localhost postfix]# /usr/local/bin/maildrop -v
maildrop 2.0.4 Copyright 1998-2005 Double Precision, Inc.
GDBM extensions enabled.
Courier Authentication Library extension enabled. //这行重要,没有的话要查一下原因
Maildir quota extension enabled.
This program is distributed under the terms of the GNU General Public
License. See COPYING for additional information.
FAQ:
如果没有显示Courier Authentication Library extension enabled.说明你的maidrop还不支持courier auth，请仔细检查，重新编译maildrop建议不要自定义目录安装，可以减少不必要的麻烦，删除很方便：直接在已经编译的源代码目录 make uninstall 就行
知道maildrop把邮件移动到哪个用户目录还是非常有必要的，这个操作就是maildrop的日志记录。这里我们创建一个新文件/etc/maildroprc，这个文件就2行内容：如果加入反SPAM,需要更改以下内容
| [root@mail mailbox]# more /etc/maildroprc logfile "/var/log/maildrop.log" to "$HOME/$DEFAULT" |
Shell> touch /var/log/maildrop.log
Shell> chown vmail.vmail /var/log/maildrop.log
shell> chown vmail.vmail /var/mailbox
三.Webmail相关包安装
一．安装webmail
安装前先安装Unix-Syslog-1.1.tar.gz
http://search.cpan.org/CPAN/authors/id/M/MH/MHARNISCH/Unix-Syslog-1.1.tar.gz
Tar zxvf Unix-Syslog-1.1.tar.gz
cd Unix-Syslog-1.1
perl Makefile.PL
make
make install
安装：DBI-1.605.tar.gz(先安装)
DBD-mysql-4.010.tar.gz
安装extmail
……………………………安装开始………………………………………………
Shell> Mkdir -p /var/www/extsuite/extmail
将下载的extmail-1.0.4.tar.gz解压到 /var/www/extsuite/extmail下
Shell> cd /var/www/extsuite/extmail/
Shell> cp webmail.cf.default webmail.cf
[Shell> chown –R vmail.vmail /var/www/extsuite/extmail]
[shell> chmod +x /var/www/extsuite/extmail/cgi]

apache 运行用户及组为vmail
二．安装webmail图形化日志
1. RRDTool安装
下载：http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.2.30.tar.gz
http://ftp.gnome.org/pub/gnome/sources/libart_lgpl/2.3/libart_lgpl-2.3.20.tar.gz(先安装)
步骤：
--------------------------------------------------------------------------------------------------
libart安装(包括了libart库文件,对平面图形的良好性能很有帮助)
# tar zxvf libart_lgpl-2.3.20.tar.gz && cd libart*
# ./configure --prefix=/usr/local/libart
# make && make install
RRDTool安装(Rrdtool 依赖libpng freetype libart库支持，安装这个前应先保证这几个库已安装上)
# tar zxvf rrdtool-1.2.30.tar.gz && cd rrd*
# more /doc/rrdbuild.txt (安装说明)
# export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/libart/lib/pkgconfig
# pkg-config --libs freetype2(检测一下是否可以找到freetype2)
-L/usr/local/lib -lfreetype -lz
# ./configure --prefix=/usr/local/rrdtool //本机需要连网

# make && make install
2．安装File-Tail perl模块
下载：http://search.cpan.org/CPAN/authors/id/M/MG/MGRABNAR/File-Tail-0.99.3.tar.gz
基本步骤：
# tar zxvf File-Tail-0.99.3.tar.gz && cd File*
# perl Makefile.PL
# make && make install
以下是安装信息：
cp Tail.pm blib/lib/File/Tail.pm
Manifying blib/man3/File::Tail.3pm
Installing /usr/lib/perl5/site_perl/5.8.8/File/Tail.pm
Installing /usr/share/man/man3/File::Tail.3pm
Writing /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/auto/File/Tail/.packlist
Appending installation info to /usr/lib/perl5/5.8.8/i386-linux-thread-multi/perllocal.pod
３．启动图形日志服务测试
Shell> cp -r /var/www/extsuite/extman/addon/mailgraph_ext /usr/local/
其它设置：(因为rrdtool安装在非标准目录，所以其perl模块找不到,拷备到标准目录即可)
cp -r /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/* /usr/lib/perl5/5.8.8/i386-linux-thread-multi/
shell> /usr/local/mailgraph_ext/mailgraph-init start
shell> /usr/local/mailgraph_ext/qmonitor-init start
加入到开机启动:
Shell> echo “/usr/local/mailgraph_ext/mailgraph-init start”>>/etc/rc.local
Echo > echo “/usr/local/mailgraph_ext/qmonitor-init start”>>/etc/rc.local

添加为支持虚拟域和虚拟用户所用到的配置文件
1. 添加为支持虚拟域和虚拟用户所用到的配置文件
创建目录/etc/postfix/mysql,然后手动创建四个配置文件：mysql_virtual_alias_maps.cf，mysql_virtual_domains_maps.cf，mysql_virtual_mailbox_limit_maps.cf，mysql_virtual_mailbox_maps.cf。这4个文件的内容分别如下：
*也可以直接从extman解压包的docs目录下直接挎备以下几个文件*
Shell> mkdir –p /etc/postfix/mysql
Shell> more mysql_virtual_alias_maps.cf
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = alias
select_field = goto
where_field = address
additional_conditions = AND active = '1'
shell> more mysql_virtual_domains_maps.cf
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = domain
select_field = domain
where_field = domain
additional_conditions = AND active = '1'
shell> more mysql_virtual_mailbox_limit_maps.cf
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = quota
where_field = username
additional_conditions = AND active = '1'
shell> more mysql_virtual_mailbox_maps.cf
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = maildir
where_field = username
additional_conditions = AND active = '1'
2. webmail登录美化
登录界面美化：
在文件/var/www/extsuite/extmail/html/default/index.html 加入下面的标识，可以得到不同
| <%domain%> |
邮件域的下拉列表，从而方便用户的使用。
在文件/var/www/extsuite/extman/html/default/index.html 加入下面的标识，可以得到不同

四.邮件反垃圾和反病毒
一．邮件反病毒和垃圾邮件过滤
1.反病毒
抗病毒使用软件是clamav
下载：http://jaist.dl.sourceforge.net/sourceforge/clamav/clamav-0.95.tar.gz
安装：
#################################################################
# tar zxvf clamav-0.95.tar.gz &&cd clamav-0.95*
# useradd clamav
# ./configure --prefix=/usr/local/clamav
--with-dbdir=/usr/local/share/clamav //定义病毒数据库目录
# make && make install
################################################################
基本配置：
###################################################################
Clamav有2个配置文件，一个主配置文件/usr/local/clamav/etc/clamd.conf，一个病毒更新配置文件 /usr/local/clamav/etc/ freshclam.conf。现把修改好的配置文件列于下面：
[root@mail etc]# sed -e '/^#/d' -e '/^$/d' clamd.conf
LogFile /var/log/clamav/clamd.log
LogSyslog yes
LogVerbose yes
PidFile /var/run/clamav/clamd.pid
DatabaseDirectory /usr/local/share/clamav
LocalSocket /var/run/clamav/clamd.socket
StreamMaxLength 100M //附件大小,超过100M不扫描
User amavis
ScanMail yes
ScanArchive yes
[root@mail etc]# sed -e '/^#/d' -e '/^$/d' freshclam.conf
DatabaseDirectory /usr/local/share/clamav
UpdateLogFile /var/log/clamav/freshclam.log
LogVerbose yes
LogSyslog yes
PidFile /var/run/clamav/freshclam.pid
DatabaseOwner amavis
DatabaseMirror db.CN.clamav.net
DatabaseMirror database.clamav.net
##################################################################
这2个文件有很多注释，我用sed把它过滤掉了。Clamd.conf中，有"User amavis"这样一行。为什么不用默认的用户clamav而使用amavis呢？这样做的目的是为了与amavis-new结合在一起。既然没有这个用户，就手动创建一个（useradd amavis）。接下来需要手动创建一些目录并赋予相应的权限，用来记录日志等用途；我把它作成一个shell脚本，直接执行即可，脚本的内容如下所示：
######################################################
[root@mailserv2 ~]# more /root/clamav.sh
#!/bin/bash
# create directory for clamav
mkdir /usr/local/share/clamav
mkdir /var/log/clamav
chmod -R 744 /var/log/clamav
chown -R amavis:amavis /var/log/clamav
chown -R amavis.amavis /usr/local/share/clamav
mkdir /var/run/clamav
chmod 700 /var/run/clamav
chown amavis.amavis /var/run/clamav
#####################################################
# /usr/local/clamav/bin/freshclam 手动更新病毒库。
2.反垃圾
下载：http://www.ijs.si/software/amavisd/amavisd-new-2.6.2.tar.gz
安装：
#################################################################
通过脚本一步到位：注意目录及版本
[root@mail virus]# vi /usr/local/bin/amavis.sh
#!/bin/bash
cd /usr/local/src/virus
tar zxvf amavisd-new-2.6.2.tar.gz && cd amavisd*
mkdir -p /var/amavis /var/amavis/tmp /var/amavis/var /var/amavis/db
chown -R amavis:amavis /var/amavis
chmod -R 750 /var/amavis
cp amavisd /usr/local/sbin/
chown root /usr/local/sbin/amavisd
chmod 755 /usr/local/sbin/amavisd
cp amavisd.conf /etc/
chown root /etc/amavisd.conf
chmod 644 /etc/amavisd.conf
mkdir /var/virusmails
chown amavis:amavis /var/virusmails
chmod 750 /var/virusmails
################################################################
执行完脚本后别忘记检查一下是否都按我们的意愿工作，如/usr/local/sbin目录是否有文件amavisd。
Amavisd的配置文件/etc/amavisd.conf比较复杂，需要修改的内容如下：
$max_servers=8;
$daemon_user = 'amavis';
$daemon_group = 'amavis';
$mydomain = 'mail.test.com';
$db_home = "$MYHOME/db";
$inet_socket_port = 10024;
$sa_tag_level_deflt = 5.0;
$sa_tag2_level_deflt = 6.2;
$sa_kill_level_deflt = $sa_tag2_level_deflt;
$virus_admin = "virusalert@$mydomain";
$sa_spam_subject_tag = '***SPAM*** ';
$forward_method = 'smtp:127.0.0.1:10025';
$notify_method = $forward_method;
$final_virus_destiny = D_DISCARD;
$final_banned_destiny = D_DISCARD;
$final_spam_destiny = D_PASS;
['ClamAV-clamd',
&ask_daemon, ["CONTSCAN {}n", "/var/run/clamav/clamd"],
qr/bOK$/, qr/bFOUND$/,
qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ],
上述修改确认无误后，执行 # /usr/local/sbin/amavisd debug 测试amavis。一般而言，测试皆不能正常进行，因为所需要的很多perl模块很可能没有被安装。还好，报错信息给出了所需的模块。这时你需要到www.cpan.org下载相关的模块，然后安装;也可能遇到包依赖，再下载依赖的包，安装这个依赖，再反回来安装先前那个包，如此反复，很是烦人，极考验人的耐性。等到/usr/local/sbin/amavisd debug 输出没有错误方才完成。有另外一种方法，即运行 [root@mailserv2 ~]# perl -MCPAN -e shell ，然后执行 cpan> install Time::HiRes 这样的命令挨个安装缺少的perl模块。根据我的经验，这样干很耗时，并且有的模块用这种方法安装还不灵，所以还不如在网站下载模块安装有效。

可能出现的问题:
Hits值总为0,可能是mail:: spamassassin没有起作用,查看一下/usr/share/spamassassin/是否有访问权限,其属主为amavis
6.病毒库和反垃圾规则更新
[root@MailSer1 ~]# crontab -l
0 0 1 * * root wget -N -P /usr/share/spamassassin www.ccert.edu.cn/spam/sa/Chinese_rules.cf;kill -HUP `cat /var/run/spamd.pid`
00 00 * * * /usr/local/clamav/bin/freshclam
补充：
垃圾邮件分捡：
# more /etc/maildroprc
logfile "/var/log/maildrop.log"
if (/^X-Spam-Flag:.*YES/)
{
exception {
to "$HOME/$DEFAULT/.Junk/."
}
}
到此，整个邮件系统安装基本完成，在安装过程中，参考了网上很多资料，同时也发现了许多问题!这几篇文章难免还有一些不足，我会不断完善，也欢迎大家指正！
