			<description><![CDATA[<p>Hi bingol,</p><p>得先分析一下到底是什么引起发邮件慢，然后再来看如何优化。禁用 SPAM/VIRUS 扫描只是其中一个可调整的参数。</p><p>可以考虑先禁用 Amavisd+SpamAssassin+ClamAV，如果性能一下就上去了，说明是这三个组件中的一个或几个导致的。再慢慢定位具体是哪个组件，以及组件里哪个/哪些功能导致速度慢。</p><p>- 要禁用 Amavisd+SpamAssassin+ClamAV，可以直接注释掉 /etc/postfix/main.cf 里的 content_filter 参数，重启 Postfix 后看看效果。<br />- 要保留 Amavisd+SpamAssassin+ClamAV，可以继续保留 content_filter 参数，但是通过启用 /etc/amavis/conf.d/ 目录里的配置文件中的以下2个参数（注意，它们是全局参数，不是在 $policy_bank 里的）来禁用 SpamAssassin + ClamAV，以此来判断是否是 Amavisd 单个组件的问题：<br /></p><div class="codebox"><pre><code>@bypass_virus_checks_maps = (1);  # controls running of anti-virus code
@bypass_spam_checks_maps  = (1);  # controls running of anti-spam code</code></pre></div><p>- 之后再继续注释掉上面2个参数中的任意一个，并做发件测试，看看到底是哪个组件引起的。</p><p>这样逐个排除，应该就能确定性能瓶颈了。</p>]]></description>

			<description><![CDATA[<p>==== 提供基本信息便于分析问题并得到快速回复 ====<br />- iRedMail 版本：0.7.4 ldap<br />- 使用的 Linux/BSD 发行版名称及版本号：freebsd 8.2<br />- 与您的问题相关的日志信息：<br />==== </p><p>张工，现使用的iredmail 0.7.4使用一直都非常好，就是群发邮件投递的速度真是太慢了（70个帐户），需要40~50分钟，导致所有进出邮件都被堵住，后面的邮件延时1个多小时。感觉好像是在内过滤还垃圾邮件SA那里花费了大量时间。</p><p>请问张工，我如何将本地用户发出去的邮件不用 过滤和反垃圾，看看是否有所改善。</p>]]></description>
