安装 重新下载编译imap4.2.0 ，EOMS光盘中的imap需要0.60以上的authlib，不与考虑。默认安装/usr/lib/courier-imap/
42.还原imapd/pop3d.dist,不启动imap服务,只启动pop3d,涉及到的AUTH 改为 LOGIN PLAIN

45.安装amavisd-new

shell
# yum install amavisd-new

设置相关目录权限：

shell
# chown -R amavis.amavis /var/spool/vscan/

46.配置SpamAssassin

Amavisd-new 通过Mail::SpamAssassin 模块来调用SA的功能，因此这里配置SA和常规配置SA软件有些区别，主要集中在修改local.cf文件上。

增加中文规则： 用于处理中文（简体）垃圾邮件。

shell
# wget -N -P /usr/share/spamassassin www.ccert.edu.cn/spam/sa/Chinese_rules.cf

设置规则自动更新：

shell
# /usr/bin/crontab -e

然后输入如下的内容：

0 0 1 * * wget -N -P /usr/share/spamassassin www.ccert.edu.cn/spam/sa/Chinese_rules.cf; /etc/init.d/amavisd restart

存盘退出即可。最后运行以下调试命令以确认amavisd没有错误：

shell
# /usr/sbin/amavisd -c /etc/amavisd.conf debug

如果没有异常提示或报错退出则表示一切都正常，按ctrl+c终止，然后正常启动，若提示pid不存在等错误，不必理会。

47.设置amavisd开机自启：

shell
# service amavisd start
# chkconfig amavisd on

48.安装ClamAV

shell
# yum install clamd

编辑clamd.conf文件

shell
# vi /etc/clamd.conf

去掉 ‘LocalSocket /var/run/clamav/clamd.sock’的注释，并注释掉 ‘TCPSocket 3310’，我们将使用unix socket而不是TCP，两者不可并存。
变动内容见下：

# Default: disabled
LocalSocket /var/run/clamav/clamd.sock

#TCPSocket 3310

设置相关目录权限：
将clamav加到amavis运行组里，并调整目录权限，否则clamav将无法扫描amavisd-new产生的临时文件

shell
# gpasswd -a clamav amavis
# usermod -G amavis clamav
# chown amavis.amavis /var/spool/vscan
# chmod 750 /var/spool/vscan
# chown amavis.amavis /var/spool/vscan/tmp
# chmod 750 /var/spool/vscan/tmp

默认的/var/spool/vscan 目录属性是：

drwxr-x---   5 amavis amavis

对于clamav用户而言，则无任何权限访问该目录，因此maillog里amavisd-new会提示:

May 19 08:38:53 as3 amavis[1752]: (01752-01) ask_av (ClamAV-clamd) FAILED - unexpected result: /var/spool/vscan/tmp/amavis-20050519T
083853-01752/parts: Access denied. ERROR\n
May 19 08:38:53 as3 amavis[1752]: (01752-01) WARN: all primary virus scanners failed, considering backups

启动ClamAV及开机自启：

shell
# service clamd start
# freshclam –daemon

49.配置amavisd.con文件

修改amavisd.conf

shell
# vi /etc/amavisd.conf

修改的主要参数如下：

$mydomain = 'extmail.org';
$db_home   = "$MYHOME/db";
$lock_file = "$MYHOME/amavisd.lock";  # -L
$pid_file  = "$MYHOME/amavisd.pid";   # -P
$myhostname = 'mail.extmail.org';
@local_domains_maps = qw(.);
@mynetworks = qw( 127.0.0.0/8 );

对本地发出的邮件不进行内容过滤
$policy_bank{'MYNETS'} = {   # mail originating from @mynetworks
originating => 1,  # is true in MYNETS by default, but let's make it explicit
os_fingerprint_method => undef,  # don't query p0f for internal clients
allow_disclaimers => 1,  # enables disclaimer insertion if available
bypass_spam_checks_maps => [1],
bypass_banned_checks_maps => [1],
bypass_header_checks_maps => [1],
};

$sa_spam_modifies_subj = 0;            # 当邮件被认为是垃圾邮件时，是否修改邮件的主题
$remove_existing_x_scanned_headers= 1; # 凡是经过 Amavisd 过滤的邮件，都会在邮件头中被加入一行邮件头信息
$remove_existing_spam_headers = 1;

# 修改投递/拦截的方法:
$final_virus_destiny      = D_DISCARD;
$final_banned_destiny     = D_DISCARD;
$final_spam_destiny       = D_PASS;
$final_bad_header_destiny = D_PASS;

# 配置Amavisd与Clamav结合
['ClamAV-clamd',
\&ask_daemon, ["CONTSCAN {}\n", "/var/run/clamav/clamd.sock"],
qr/\bOK$/, qr/\bFOUND$/,
qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ],
);

@av_scanners_backup = (
['ClamAV-clamscan', 'clamscan',
"--stdout --no-summary -r --tempdir=$TEMPBASE {}",
[0], qr/:.*\sFOUND$/, qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ],
);

amavisd.conf常用参数说明：

$max_servers = 10;                   设置最大可使用的进程数
$sa_spam_subject_tag = '[SPAM] ';    加 [SPAM] 标记
$mydomain = 'mail.extmail.org';      设置域名
$myhostname = 'mail.extmail.org';    设置主机名
@local_domains_maps = qw(.);         对所有的域检查
$sa_tag2_level_deflt = 5.0;          超过这个分数，允许在邮件标题加入[SPAM] 标记
$sa_kill_level_deflt = 5.0;          超过这个分数，直接將信件备份后删除
$final_virus_destiny:                检测到病毒时的动作
$final_banned_destiny:               检测到受禁止的内容时的动作
$final_spam_destiny:                 检测到垃圾邮件、广告邮件（spam）时的动作
$final_bad_header_destiny：          检测到不良信件时的动作

默认有以下几种动作：
D_PASS:                              无论信件是否有问题，都会将信件发给收件人
D_DISCARD:                           信件将被丢弃，并且不会告知收件人及发件人
D_BOUNCE:                            信件不会发送给收件人，但会通知发件人邮件没有被投递
D_REJECT:                            邮件不会被投递给收件人，但会通知发件人邮件被拒绝

注意事项：

上述$mydomain参数与$myhostname参数相同，主要是为了方便之后的病毒/垃圾汇报邮件发给系统管理员时，能投递到本地的别名里，再转交到虚拟域的特定用户。

50.配置Postfix 集成amavisd-new

增加邮件别名

shell
# vi /etc/postfix/aliases

增加如下信息，注意：默认的aliases数据库里已有一条virusalert的别名，请删除，再输入下面的别名记录，并确保所有记录都是唯一的：

virusalert:    root
spam.police:   root
postfix:       test@extmail.org

保存并执行newaliases命令生成新的别名数据库，重新启动amavisd：

shell
# newaliases
# service amavisd restart

编辑master.cf文件：

shell
# vi /etc/postfix/master.cf

增加如下内容：

smtp-amavis unix    -    -    n    -    3    smtp
-o smtp_data_done_timeout=1200
-o smtp_send_xforward_command=yes
-o disable_dns_lookups=yes
-o max_use=10

127.0.0.1:10025 inet    n       -       n       -       -       smtpd
-o content_filter=
-o local_recipient_maps=
-o relay_recipient_maps=
-o smtpd_restriction_classes=
-o smtpd_client_restrictions=
-o smtpd_helo_restrictions=
-o smtpd_sender_restrictions=
-o smtpd_recipient_restrictions=permit_mynetworks,reject
-o mynetworks=127.0.0.0/8
-o strict_rfc821_envelopes=yes
-o smtpd_error_sleep_time=0
-o smtpd_soft_error_limit=1001
-o smtpd_hard_error_limit=1000
-o receive_override_options=no_unknown_recipient_checks,no_header_body_checks

编辑main.cf文件：

shell
# vi /etc/postfix/main.cf

增加如下内容：

# Content-Filter
content_filter = smtp-amavis:[127.0.0.1]:10024
receive_override_options = no_address_mappings

注意：receive_override_options 这里必须增加，禁止地址展开/影射，否则如果遇到别名的时候会引起冗余邮件的产生。

重启postfix ：

shell
# service postfix restart

重新启动amavisd：

shell
# service amavisd restart

51.测试Clamav

shell
# telnet localhost 25

其过程如下:

Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
220 mail.extmail.org ESMTP Postfix - by extmail.org
mail from:<postmaster@extmail.org>     << 输入内容
250 2.1.0 Ok
rcpt to:<test@extmail.org>     << 输入内容
250 2.1.5 Ok
data     << 输入内容
354 End data with .
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*     << 输入内容
.
250 2.0.0 Ok: queued as BC24E85260
quit     << 输入内容
221 2.0.0 Bye
Connection closed by foreign host.

在邮件日志里，应该有相应的信息出现：

Mar 22 06:43:15 localhost amavis[15405]: (15405-01) Blocked INFECTED (Eicar-Test-Signature), [192.168.0.235] ->, quarantine:
virus-mI6vbjkWZ2Tz, Message-ID: <003401c88c1a$74706360$eb00a8c0@nbk00045>, mail_id: mI6vbjkWZ2Tz, Hits: -, size: 1757, 474 ms

如果看到类似这样的日志，表明Clamav+Amavisd-new工作正常。

52.安装Spam_Locker

shell
# yum install extsuite-slockd

配置resolv.conf

请确认/etc/resolv.conf里的dns服务器是离你的邮件服务器最近，速度最快的dns server，slockd很依赖dns的好坏，因此给系统配置一个快速的dns能大幅度提高处理速度。以下给出一个配置仅供参考:

shell
# vi /etc/resolv.conf

增加以下内容：

nameserver 202.96.209.6

上述dns服务器是上海电信的DNS服务器，对于非广东朋友，请改为离你最近的DNS服务器IP，如果可能的话，请配置一个简单的bind，成为本地的 dns cache server，可以获得最高性能。这里略过这一步骤，但您必须确保dns的配置是正确并且可靠的，否则slockd将不能工作！

53.测试slockd

启动slockd

shell
# /usr/local/slockd/slockd-init start

此时slockd将启动，并进入非daemon方式的监听模式，接受来自10030端口的请求，命令行下将显示如下调试信息：

Starting spam locker daemon: slockd
starting child 2908
starting child 2909

打开另一个ssh/终端窗口：

shell
# cd /usr/local/slockd/tools

输入：

shell

# perl policy_sig -h localhost -p 10030 --helo FOOBAR --ip 192.168.0.1 --from test@foo.com --to test@bar.com

此时，程序应该返回如下错误信息：这表示slockd初步的正常工作了。

action=554 blocked using zen.spamhaus.org, see http://bl.extmail.org/cgi/rbl?192.168.0.1
设置slockd开机自启动

shell
# /usr/local/slockd/slockd-init start # echo “/usr/local/slockd/slockd-init start” >> /etc/rc.d/rc.local

54.配置Postfix

slockd调试正常后，必须配置postfix以使其打开对slockd的支持。

编辑main.cf文件

shell
# vi /etc/postfix/main.cf

将 check_policy_service inet:127.0.0.1:10030 这一行记录增加到smtpd_recipient_restrictions 里，例如：

smtpd_recipient_restrictions =
permit_mynetworks,
permit_sasl_authenticated,
reject_non_fqdn_hostname,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unauth_destination,
reject_unauth_pipelining,
reject_invalid_hostname,
check_policy_service inet:127.0.0.1:10030

重新启动postfix以使配置生效

shell
# service postfix restart

注意事项： 上述配置是将slockd的查询放到最后，这也是进一步提高资源利用律的办法，因为有部分功能postfix已实现了，所以就先由postfix检测，如果检测不到再由slockd完成。

55.安装dspam

Dspam的配置主要参考《Dspam+Amavis-new+SA-Clamav for EMOS》

链接: http://www.extmail.org/forum/viewthread.php?tid=10393&extra=&page=1
shell
# yum install dspam-mysql

56.导入 DSPAM 训练库

shell
# cd /root/
# wget http://www.extmail.org/download/misc/dspam/dspam-trained-data.sql.gz # gzip -d dspam-trained-data.sql.gz
# rm -rf /var/lib/mysql/dspam/ (备注：如果没有dspam的库，可以不用执行)
# mysql -u root -p -e “create database dspam”
# mysql -u root -p -e “grant all on dspam.* to dspam@localhost identified by ‘dspam’”
# mysql -u dspam -p dspam dspam < /root/dspam-trained-data.sql

DSPAM的token数据库的定时清理：

shell
# crontab -e

加入以下内容：

0 0 * * * /usr/bin/mysql -u dspam -p'dspam' dspam < /usr/share/dspam/sql/mysql/purge.sql
0 0 * * * /usr/bin/dspam_logrotate -a 30 -d /var/spool/dspam/data

57.配置 dspam.conf 文件

shell
# vi /etc/dspam/dspam.conf

变动内容如下：

DeliveryHost 127.0.0.1
DeliveryPort 10024
DeliveryIdent localhost
DeliveryProto SMTP

Trust extmail

Preference "signatureLocation=headers" # 'message' or 'headers'
Preference "showFactors=off"

MySQLUIDInSignature on
MySQLServer /var/lib/mysql/mysql.sock
MySQLUser dspam
MySQLPass dspam
MySQLDb dspam
MySQLCompress true

MySQLConnectionCache 10

ServerPort 10028
ServerQueueSize 32
ServerPID /var/spool/dspam/dspamd.pid
ServerMode auto
ServerPass.Relay1 "secret"
ServerParameters "--user extmail --deliver=innocent,spam"
ServerIdent "localhost.localdomain"

ClientHost 127.0.0.1
ClientPort 10028
ClientIdent "secret@Relay1"

58.启动 dspam 进程

shell
# chkconfig dspamd on
# service dspamd start

查看dspam启动进程

shell
# ps aux |grep dspam

显示以下内容：

dspam 18407 0.0 0.5 5452 1344 pts/0 S 19:16 0:00 /usr/sbin/dspamd --daemon
root 18412 0.0 0.2 5140 668 pts/0 S+ 19:17 0:00 grep dspamd

59.修改main.cf文件

shell
# vi /etc/postfix/main.cf

增加以下内容:

header_checks = regexp:/etc/postfix/dspam_header_checks

设置邮件标题过滤管理 以防止重复X-DSPAM-Signature标题，可以防止签名被报道为垃圾。这发生在当你从一个已经运行Dspam的服务器收到邮件,或被用于通过伪造的、滥发邮件来阻止你训练数据库,

shell
# vi /etc/postfix/dspam_header_checks

增加以下内容:

/^(X-DSPAM-.*)/ IGNORE
/^(X-Spam-.*)/ IGNORE

重启postfix ：

shell
# service postfix restart

60.编辑 amavisd.conf 文件

shell
# vi /etc/amavisd/amavisd.conf

增加以下内容：

$dspam = '/usr/bin/dspam';
@spam_scanners = (
['SpamAssassin', 'Amavis::SpamControl::SpamAssassin'],
['DSPAM', 'Amavis::SpamControl::ExtProg', $dspam,
[ qw(--client --stdout --deliver=spam,innocent --mode=teft --user extmail)],
],
);

SA增加DSpam插件：

shell
# cd /usr/lib/perl5/vendor_perl/5.8.8/Mail/SpamAssassin/Plugin/
# wget http://www.extmail.org/download/misc/dspam/dspam.pm
编辑 local.cf 文件

shell
# cd /etc/mail/spamassassin/
# wget http://www.extmail.org/download/misc/dspam/dspam.cf # vi local.cf

在下面增加以下内容

include dspam.cf

编辑 init.pre 文件：

shell
# vi init.pre

在下面增加以下内容

loadplugin Mail::SpamAssassin::Plugin::dspam

重启amavisd

shell
# service amavisd restart

61.增加 extmail 的垃圾邮件举报

说明：
Extmail 1.0.9正式加入垃圾邮件举报功能，主要基于(xueron)的补丁包，并进行了一定的调整，使该功能可以兼容DSPAM及Spamassassin两种内容过滤软件的训练。
Extmail1.1.1加入(stvictor)提供的spamassassin举报功能，感谢！

修改 webmail.cf

shell
# vi /var/www/extsuite/extmail/webmail.cf

主要变动的内容如下：

SYS_SPAM_REPORT_ON = 1
SYS_SPAM_REPORT_TYPE = dspam

设置maidrop的全局过滤

shell
# vi /etc/maildroprc

内容如下：

# Decoder for high quality key word filtering
# Author: hzqbbc <hzqbbc@hzqbbc.com> - ExtMail Dev Team
DECODER="/var/www/extsuite/extmail/tools/decode -v"
if ((/^(From|Sender|Return-Path):.*MAILER\-DAEMON/))
{
BADSENDER=1
}

# Custom filter and auto deliver to Junk mailbox support
# need test command and other Unix command
`test -f $HOME/.mailfilter && exit 1 || exit 0`

# No customize filtering rules
if ( $RETURNCODE == 0 )
{
if (/^X-Spam-Flag:.*YES/ || /^X-DSPAM-Result:.*Spam/)
{
exception {
to "$HOME/Maildir/.Junk/."
}
}
}

62.配置DSPAM Web 界面

安装相关的rpm包:

shell
# yum install perl-GDGraph
# yum install perl-GD-Graph3d
# yum install dspam-web

创建dspam-web 认证用户:

shell
# cd /usr/share/dspam/webui/cgi-bin
# echo “extmail” > admins
# htpasswd -c .htpasswd extmail

输入认证密码

New password:
Re-type new password:
Adding password for user extmail

启动 dspam-web 守护进程

shell
# service dspam-webd start

这实际是启动了mini_httpd进程，查看 mini_httpd 是否启动正常：

shell
# ps aux |grep mini

显示以下内容：

dspam 18580 0.0 0.3 4152 820 ? Ss 20:05 0:00 mini_httpd -C /etc/dspam/webui.conf
root 18582 0.0 0.2 5316 668 pts/0 S+ 20:05 0:00 grep mini

重启 apache

shell
# service httpd restart

访问 dspam-web
http://mail.example.com/dspam
输入你在 .htpasswd 文件中创建的用户和密码

63.增加FCGI支持

下载地址： http://www.fastcgi.com/dist/mod_fastcgi-2.4.6.tar.gz
安装mod_fastcgi ：

shell
# wget http://www.fastcgi.com/dist/mod_fastcgi-2.4.6.tar.gz # tar xfz mod_fastcgi-2.4.6.tar.gz
# cd mod_fastcgi-2.4.6
# cp Makefile.AP2 Makefile 注意：还原Makefile后情参考本地情况修改Makefile
# vi Makefile
# Makefile for Apache2
#

builddir = .

top_dir = /etc/httpd

top_srcdir = ${top_dir}
top_builddir = /usr/lib64/httpd

include /usr/lib64/httpd/build/special.mk

APXS = apxs
APACHECTL = apachectl

#DEFS=-Dmy_define=my_value
#INCLUDES=-Imy/include/dir
#LIBS=-Lmy/lib/dir -lmylib

#mail.daodaoly.net
INCLUDES=-I /usr/include/httpd -I /usr/include/apr-1

all: local-shared-build

clean:
-rm -f *.o *.lo *.slo *.la

# make install

安装perl-FCGI 除了Apache需要FCGI的支持外，extmail也需要相应的perl-FCGI模块。

shell
# yun install perl-FCGI

配置虚拟主机：

shell
# vi /etc/httpd/conf/vhost_extmail.conf

增加内容如下：

LoadModule fastcgi_module modules/mod_fastcgi.so

<Ifmodule mod_fastcgi.c>
FastCgiExternalServer /usr/bin/dispatch.fcgi -host 127.0.0.1:8888 -idle-timeout 240
</Ifmodule>

#同时，去掉如下行：
#ScriptAlias /extmail/cgi/ /var/www/extsuite/extmail/cgi/

#改为：
Alias /extmail/cgi/ /usr/bin/dispatch.fcgi/ #注意如果发现升级FCIG后主目录不符，可重新alias /extmail
<Location "/extmail/cgi">
SetHandler fastcgi-script
</Location>

重启Apache和fastcgi server开机自启动：

shell
# service httpd restart
# /var/www/extsuite/extmail/dispatch-init start
# echo “/var/www/extsuite/extmail/dispatch-init start” >> /etc/rc.d/rc.local

完。

另外：slockd严格策略导致邮件接受不正常，可以修改/usr/local/slockd/config/whitelist加入
