张工，你好！
之前因反垃圾邮件和反病毒功能影响邮件发送效率，后来我停用了该功能。但后来因需要，重新启用反垃圾邮件功能（未启用反病毒功能）并做了小部分的调整。但是从效果上看感觉并没有起到反垃圾的作用。下面是我做的一些调整，麻烦张工帮我分析下对不对。
1.    修改配置文件main.cf
# 启动邮件内容过滤器，去掉以下参数前的注释
content_filter = smtp-amavis:[127.0.0.1]:10024
2.    修改配置文件amavisd.conf
# 取消病毒扫描功能，去掉以下参数前的注释
@bypass_virus_checks_maps = (1);  # controls running of anti-virus code
# 取消对macrodata.com域名发起邮件的扫描，新增以下参数
$policy_bank{'ORIGINATING'} = {
…
# 20161010
  # don't perform spam/virus/header check.
  bypass_spam_checks_maps => [1],
  bypass_virus_checks_maps => [1],
  bypass_header_checks_maps => [1],

  bypass_banned_checks_maps => [1],  # allow sending any file names and types
…
}
# 取消对我司邮件客户端发起邮件的扫描，去掉以下参数前的注释
$policy_bank{'MYUSERS'} = {
…
    # don't perform spam/virus/header check.
    bypass_spam_checks_maps => [1],
    bypass_virus_checks_maps => [1],
    bypass_header_checks_maps => [1],
   
# allow sending any file names and types
bypass_banned_checks_maps => [1],
     …
     }
3.    启动扫描相关服务
chkconfig clamd.amavisd on
chkconfig spamassassin on
4.    重启服务
/etc/init.d/clamd.amavisd start
/etc/init.d/spamassassin start
/etc/init.d/amavisd restart
postfix reload

}

这里的几个 bypass_ 就表示禁用垃圾扫描了。你应该把它们都注释掉。
另外，新版本的 iRedMail 里已经不使用 $policy_bank{'MYUSERS'} 了。

我现在主要是希望邮件系统不要对我的域名发起的邮件进行扫描，所以参考了这篇文章（http://www.iredmail.com/docs/disable.spam.virus.scanning.for.outgoing.mails.html）做了配置。
按张工的意思说，
1.0.9.0版本里在$policy_bank{'MYUSERS'}配置什么都是无效的；
2.为了提高发件速度，禁止对我的域名发起的邮件进行扫描的话，那我应该怎么配置呢？

你不觉得这里有矛盾么？你配置了不扫描，那 spamassassin 对于你外发的邮件当然就不生效了。

iRedMail 这两年发布的版本里都不用 $policy_bank{'MYUSERS'} 了。如果你配置了，还是会生效的。它包含 $policy_bank{'ORIGINATING'} 和 $policy_bank{'MYNETS'}。重复了，所以就不用了。

我只是希望反垃圾邮件功能能够区别扫描邮件，对于自己域名发件人发邮件给其他域名时不过滤，但对于其他域名发件人发送给我域名的邮件能够进行过滤。

对于收到的邮件，上面的配置是没问题的，会进行扫描。你可以按照这个文档设置一下 amavisd，从更详细的 log 里检查它是否有在运行：

张工，我注释了$policy_bank{'MYUSERS'} 中的配置，反垃圾邮件功能已经生效。但是并没有按我预期的对自己域名不进行扫描方式生效。用户发邮件时全部都通过amavisd进行扫描。严重影响了邮件收发效率。
不知道对于反垃圾邮件这部分功能该如何进行优化，请张工给点建议。谢谢！

iRedMail-0.9.0 还没有对收到的和发出的信做具体区分，你需要这样调整一下：

*) 确保 Amavisd 的 "$inet_socket_port" 参数里有 10024, 10026, 9998 三个端口。

$inet_socket_port = [10024, 10026, 9998];

*) 在 /etc/postfix/master.cf 里，确保 submission 使用 10026 端口作为内容过滤：

submission ...
    ...
  -o content_filter=smtp-amavis:[127.0.0.1]:10026

这样就ok了。这部分修改在 iRedMail-0.9.3 的升级文档里有提及：

张工，您好！
我已经根据您提供的文章修复bug，但是即使配置$policy_bank{'ORIGINATING'} = {}，只过滤外部邮件。目前效果上也还是严重影响邮件发送效率。不知道张工有没有其他高效的反垃圾邮件的方法。请告知，谢谢！

我似乎没搞懂你到底要达到怎样的一个效果，可否重新列一下你的各个要求？

回复: 启用反垃圾邮件功能，从效果来看没有生效

启用反垃圾邮件功能，过滤垃圾邮件，但因之前反垃圾反病毒功能影响邮件发件效率，因此希望能高效实现反垃圾功能，具体要求如下：
1.启用反垃圾邮件功能，无需启用反病毒功能；
==》已做调整：
# 取消病毒扫描功能，去掉以下参数前的注释，以下参数是amavisd.conf中的全局变量
@bypass_virus_checks_maps = (1);  # controls running of anti-virus code
2.限制仅扫描外部邮件；
==》已做调整：
a).参考文章http://www.iredmail.com/docs/disable.spam.virus.scanning.for.outgoing.mails.html以达到仅扫描来自外部邮件的功能。
b).参考文章http://www.iredmail.com/docs/upgrade.iredmail.0.9.2-0.9.3.html#amavisd-fix-incorrect-setting-which-treats-external-sender-as-internal-修复amavisd不区分外部用户bug。
做了以上变更后，邮件服务器发件效率仍然很低，很多发送请求均阻塞在邮件队列中，过很久才能完成发送。现在又关闭了邮件反垃圾邮件功能，希望寻求更高效的反垃圾解决方案。

*) 发件效率，在 Amavisd 的 policy bank 'ORIGINATING' 中关闭病毒、垃圾邮件、bad-header等扫描后应该是很快的。贴一下你的 amavisd 里这部分的设置，以及贴一下 /etc/postfix/master.cf 里 submission 的设置。

*) 发送邮件是用 submission（587端口+TLS）吧？

*) 服务器有多少GB内存？参考一下这篇：
http://www.iredmail.com/docs/concurrent.processing.html

另外，还需要分析为何阻塞，再来解决。现在说的只是一些通用的提升效率的办法和调整。

关于阻塞分析具体需要怎么做，还请张工指教。

服务器30GB内存，参考下面文档，将并发处理邮件数量调高到30封：
http://www.iredmail.com/docs/concurrent.processing.html

贴的 amavisd／postfix 配置没问题。

张工，我已经根据你给的参考文档里调整了。调整后队列里堵了很多其他域发来的邮件（大部分应该是垃圾邮件），但这也同时影响了部分自己域发的邮件堵在队列里。我想了解下这个邮件在队列里的处理原理，因为我前面是做了自己域发的邮件不做过滤的策略，队列中是不是会优先处理自己域发的邮件，还是根据max_server数量并行按照队列顺序一个个处理。

目前部分垃圾邮件已经标识出来，并打上SPAM的标签。但是垃圾邮件并没有进入垃圾邮箱，是因为现在的垃圾邮件机制就是打上标签而不进入垃圾邮箱吗？

投递到垃圾箱是由全局或个人的 sieve 过滤规则决定的。

iRedMail 在 dovecot.conf 里使用 sieve_before 参数定义全局 sieve 规则的文件路径。用户个人的可以在 webmail 里定义。
