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！

张工，您好！
我已经根据您提供的文章修复bug，但是即使配置$policy_bank{'ORIGINATING'} = {}，只过滤外部邮件。目前效果上也还是严重影响邮件发送效率。不知道张工有没有其他高效的反垃圾邮件的方法。请告知，谢谢！
对于收到的邮件，上面的配置是没问题的，会进行扫描。你可以按照这个文档设置一下 amavisd，从更详细的 log 里检查它是否有在运行：
http://www.iredmail.com/docs/no.x-spam.headers.html
张工，我注释了$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！
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。
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？

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
查看了下，是这个原因造成的。谢谢！

系统日志中一直报这个错误，之前因为邮件收发慢的问题将clamav和spamssassin过滤功能关闭，现在想重新开启，于是将main.cf配置文件中的content_filter = smtp-amavis:[127.0.0.1]:10024的注释去掉，但是去掉注释后用户就发不出邮件了，且日志里一直报错。不知道是什么原因导致的，smtp_sasl_password_maps参数也是默认值（空），没有另行设置。
-rw------- 1 vmail vmail 8904712 6月 28 08:25 /var/log/dovecot-sieve.log
文件存在，且只有vmail用户有读写权限。而且这种错误只有少量的，如果没有文件，在邮件投递的过程中应该会全部报这个错吧。所以我现在也很疑惑到底是什么原因造成的。

张工，邮件日志里还是有少量这种类型的邮件退信日志。虽然日志里已经说明没有权限访问这个文件（上面是文件的权限），但是我理解是不是有什么其他原因造成的。

张工，邮件退信时dovecot组件还报了这些错误。看起来像是dovecot与数据库对接时有问题，不知道这个该怎么处理。
=======dovecot.log

张工，调整完后还是存在少量的退信问题，其中报错日志如上。是不是由于dovecot服务中处理限制的值过小导致的。是否把default_process_limit参数值调大点即可。还是说有其他什么原因造成以上错误。

-rw------- 1 vmail vmail 32370055 6月 24 09:22 dovecot-sieve.log
还有，日志中报了少量无法打开日志文件，没有权限的问题。我看了下，应该是对该文件有读写的权限，不知道是什么原因导致的。

张工，邮件日志里还有上面几种发送邮件失败的错误(virtual_mailbox_domains lookup failure)，(address resolver failure)，(Temporary lookup failure)，不知道是不是因为数据库连接数不够引起的，还是有其他的原因。

张工，我看了下dovecot.log日志提示数据库连接数不够，已经调整了max_connections参数，但dovecot-sieve.log日志中的错误信息不是很明白，还要做其他调整吗？
邮件服务我在main.cf中注释了content_filter配置，amavisd配置中注释了bypass_spam_checks_maps => [1],bypass_virus_checks_maps => [1],bypass_header_checks_maps => [1]配置，关闭了杀毒和内容过滤的功能，但检查时amavisd和clamd服务仍在跑，不知道和这个有没有关系。

张工，你好！我们公司同事在发邮件（发给将近500个用户）时，出现了大量的temporary failure错误，最终有100多个用户发送失败。之前iredapd升级过，我这边用的是iRedAPD-1.6.0。不知道这是什么问题导致的，该如何解决，请帮忙解答下。谢谢！
