2、中文字体美化

(1) 方案一： 微软黑体 Lucida Grande

这里我们采用“微软黑体＋苹果字体”美化方案，效果还是十分不错的。首先从 这里 下载相关字体文件，解压后得到Lucida Grande和msyh两个字体文件，将这两个文件放到 .fonts 目录下。然后执行一下命令：
$ sudo fc-cache -fv

接着编辑字体配置文件 /etc/fonts/language-selector.conf (如果 /etc/fonts 目录下没有这个文件，可以在 /usr/share/language-selector/fontconfig 目录下找到相应的版本)， 找到下面的几行：
<family>Bitstream Vera Serif</family>
<family>Bitstream Vera Sans</family>
<family>Bitstream Vera Sans Mono</family>
在后面添加一行
<family>Microsoft YaHei</family>

编辑 /etc/apt/sources.list文件，添加源：
deb http://www.telemail.fi/mlind/ubuntu gutsy fonts
执行一下命令导入key，并进行更新：
gpg --keyserver subkeys.pgp.net --recv-keys 937215FF
gpg --export --armor 937215FF | sudo apt-key add -
sudo apt-get update && sudo apt-get dist-upgrade
（这将添加字体的cleartype渲染功能）

最后调整字体选项，非等宽字体选择Lucida Grande，9号，等宽字体选择DejaVu Sans Mono，9号。“字体渲染选择“次像素平滑”。

方案二：宋体＋Tahoma

采用“宋体＋Tahoma”得到的美化效果也是相当不错的。中文使用宋体，英文使用Tahoma。对于习惯了Windows下的字体的用户来说，这是个不错的选择。

将Windows下的simsun.ttc tahoma.ttf verdana.ttf verdanab.ttf verdanaz.ttf tahomabd.ttf verdanai.ttf拷贝到/usr/share/fonts/windows下。然后进入/usr/share/fonts/windows目录 中：

$ cd /usr/share/fonts/windows
$ sudo mkfontscale
$ sudo mkfontdir
$ sudo fc-cache -fv
(如果fc-cache命令提示刷新失败，尝试对每一个刷新失败的目录和文件使用sudo touch命令)
$ sudo chmod 755 *

用这个 language-selector.conf 配置文件替换/etc/fonts/language-selector.conf。

设置GNOME的字体。除了等宽字体外，其他的选择Tahoma，等宽字体用DejaVu Serif Mono。

# auth-mysql-mail-group: (group-name | gid)
# The group name or gid under which access to the mailspool will take place.
# [default: group of user associated with virtual domain]
auth-mysql-mail-group: vmail

# auth-mysql-hostname: hostname [[hostname] hostname] ..
# Host on which to connect to MySQL. Tried in order until a working host is
# found. [default: localhost]
auth-mysql-hostname: localhost

# auth-mysql-database: database
# MySQL database to use for authentication.
auth-mysql-database: yourdatabase

# auth-mysql-username: username
# MySQL username used to access the database.
auth-mysql-username:  yourusername

# auth-mysql-password: password
# Password of MySQL user.
auth-mysql-password: yourpassword

# auth-mysql-pass-query: substitution string
# Query template to use for USER/PASS authentication. Must return mailpath,
# password, userid, mailspool type; uses substitution variables as described
# in the man page.
#auth-mysql-pass-query: SELECT mailpath, password, userid, spooltype FROM ...
auth-mysql-pass-query:  SELECT CONCAT('/var/mail/', maildir), \
                    CONCAT('{crypt}', password),      \
                    'vmail', 'bsd'                \
               FROM mailbox                          \
              WHERE username = CONCAT('$(local_part)', '@', '$(domain)')
由于没有使用vmail-sql中的数据库schema，则要将auth-mysql-pass-query配置参数修改成符合你本地数据库schema的查询条件。详细情况参见：
http://www.ex-parrot.com/~chris/tpop3d/tpop3d.conf.5.html 的A note on MySQLauthentication部分

The following options are currently available for SCSI disks and tape drives unless otherwise noted:

简单用法：
1、smartctl -a  <device>         检查该设备是否已经打开SMART技术。
2、smartctl -s on <device>    如果没有打开SMART技术，使用该命令打开SMART技术。
3、smartctl -t short <device>    后台检测硬盘，消耗时间短；
      smartctl -t long <device>      后台检测硬盘，消耗时间长；
      smartctl -C -t short <device> 前台检测硬盘，消耗时间短；
      smartctl -C -t long <device>  前台检测硬盘，消耗时间长。
其实就是利用硬盘SMART的自检程序。
4、smartctl -X <device>  中断后台检测硬盘。
5、smartctl -l selftest <device>  显示硬盘检测日志。
6、smartctl -l error <device> 显示硬盘错误汇总。

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 744 *.php *.css
cd admin/
chmod 744 *.php .ht*
cd ../images/
chmod 744 *.gif *.png
cd ../languages/
chmod 744 *.lang
cd ../templates/
chmod 744 *.tpl
cd ../users/
chmod 744 *.php

导入数据库

mysql -uroot -p  < DATABASE_MYSQL.TXT

cp config.inc.php.sample config.inc.php

修改config.inc.php文件中相关配置

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"。

 设置Courier-IMAP开机自动运行：
cp courier-imap.sysvinit /etc/rc.d/init.d/imapd
chmod 755 /etc/rc.d/init.d/imapd
chkconfig --add imapd

测试POP3：

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 \

--with-authmysql --with-mysql-libs=/usr/local/mysql/lib/ \
--with-mysql-includes=/usr/local/mysql/include/ --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

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

设置Courier authentication library开机自动运行，在/etc/rc.local中增加“/usr/local/courier-authlib/sbin/authdaemond start”。

通过以下命令获得test@example.com的用户名及密码的BASE64编码：

perl -e 'use MIME::Base64; print encode_base64("test\@example.com")'

perl -e 'use MIME::Base64; print encode_base64("123")'
MTIz

DEBUG_LOGIN=2    原来默认是0

然后看看/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.安装amavisd

官方下载地址：http://www.ijs.si/software/amavisd/#download
wget http://www.ijs.si/software/amavisd/amavisd-new-2.4.3.tar.gz
 
升级file，可以通过file -v看一下版本，要求4.06版本以上
wget ftp://ftp.astron.com/pub/file/file-4.17.tar.gz
 

安装以下文件，这些都是安装amavisd需要的 
perl -MCPAN -e shell
cpan>install Archive::Tar  
cpan>install Archive::Zip  
cpan>install Compress::Zlib
cpan>install Convert::UUlib
cpan>install MIME::Base64  
cpan>install Mail::Internet
cpan>install Net::Server   
cpan>install Net::SMTP     
cpan>install Digest::MD5  
cpan>install IO::Stringy   
cpan>install Time::HiRes  
cpan>install Unix::Syslog  
cpan>install BerkeleyDB
cpan>install Convert::TNEF
cpan>install MIME::Parser
cpan>install MIME::Tools    
注：如果使用上述方法不能安装某些模块时，就去: http://search.cpan.org/ 搜索相应模块安装.

perl模块安装方法:
wget http://search.cpan.org/CPAN/authors/id/G/GA/GAAS/Digest-MD5-2.36.tar.gz
tar zxvf Digest-MD5-2.36
cd Digest-MD5-2.36
perl Makefile.pl
make
make test
make install

升级perl到最新版本，至少5.8.2以上版本
wget http://www.perl.com/CPAN/src/stable.tar.gz
tar zvxf stable.tar.gz
cd perl-5.8.8
./configure.gnu --prefix=/usr -Dpager="/bin/less -isR"
make
make test   测试一下，没问题后再install
make install

注意升级perl的话，可能会造成系统的其他perl应用不正常，请慎重升级，一般redhat9.0默认的5.8.0应该也没问题
 
mkdir -p /var/amavis /var/amavis/tmp /var/amavis/var /var/amavis/db /var/amavis/home
 
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

#=====================================
 
修改 /etc/amavisd.conf 

$mydomain = 'example.com';                
$myhostname= 'mail.example.com';   

$virus_admin               = "postmaster\@$mydomain";  # notifications recip.
$mailfrom_notify_admin     = "postmaster\@$mydomain";  # notifications sender
$mailfrom_notify_recip     = "postmaster\@$mydomain";  # notifications sender
$mailfrom_notify_spamadmin = "postmaster\@$mydomain"; # notifications sender
$mailfrom_to_quarantine = ''; # null return path; uses original sender if undef

$max_servers = 10;
$sa_spam_subject_tag = '[垃圾邮件] ';
@local_domains_maps = qw(.);
$sa_tag2_level_deflt = 5.0;
$sa_kill_level_deflt = 5.0;

并增加如下参数（默认amavisd.conf没有）：

$sa_spam_modifies_subj = 0; # don't modify subject  
$remove_existing_x_scanned_headers= 1; # remove existing headers
$remove_existing_spam_headers = 1;

注：$sa_spam_modifies_subj = 1;则代表修改邮件主题。

加入对Clamav 的支持：

# ### http://www.clamav.net/
 ['ClamAV-clamd',
   \&ask_daemon, ["CONTSCAN {}\n", "/var/run/clamav/clamd"],
   qr/\bOK$/, qr/\bFOUND$/,
   qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ], 

在110行左右，修改投递/拦截的方法：

$final_virus_destiny      = D_DISCARD;
$final_banned_destiny     = D_BOUNCE;
$final_spam_destiny       = D_PASS;
$final_bad_header_destiny = D_PASS;

注意上述4个设置中，对spam（垃圾邮件）默认会直接反弹（BOUNCE），现在修改为继续投递（PASS）但在信头中增加相关X-Spam- Status信息等。这样可以很方便的在extmail中设置将被标记为垃圾邮件的mail投递到“垃圾邮件箱”中，便于用户翻查，这样就避免误判垃圾邮件而引起的损失。

=====================================

3.安装SpamAssassin

perl -MCPAN -e shell
cpan>install Digest::SHA1
cpan>install HTML::Parser
cpan>install Net::DNS
cpan>install Mail::SPF::Query
cpan>install IP::Country
cpan>install Net::Ident
cpan>install IO::Socket::INET6
cpan>install IO::Socket::SSL
cpan>install DBI
cpan>install LWP::UserAgent
cpan>install Mail::SpamAssassin

注：如果使用上述方法不能安装某些模块时，就去: http://search.cpan.org/ 搜索相应模块安装.

[Incompat 20051220] The Postfix-with-Cyrus-SASL build procedure has
changed. You now need to specify -DUSE_CYRUS_SASL in addition to
-DUSE_SASL_AUTH or else you end up without any Cyrus SASL support.
The error messages are:

    unsupported SASL server implementation: cyrus
    unsupported SASL client implementation: cyrus
