Amazon SES，了解错误并避免暂停答案

【问题标题】：Amazon SES, understand errors and avoid suspensionAmazon SES，了解错误并避免暂停
【发布时间】：2015-04-02 08:47:59
【问题描述】：

我开始使用 Amazon SES 发送简报（超过 3 万封电子邮件）。我有 2 个问题。

错误

我收到很多这样的错误：

Diagnostic-Code: smtp; 554 4.4.7 Message expired: unable to deliver in 840 minutes.<421 4.4.0 Unable to lookup DNS for DOMAIN.it>
Diagnostic-Code: smtp; 554 4.4.7 Message expired: unable to deliver in 840 minutes.<421 <CASELLA@alice.it> Service not available - too busy>
Diagnostic-Code: smtp; 554 4.4.7 Message expired: unable to deliver in 840 minutes.<421 4.4.1 Failed to establish connection>
Diagnostic-Code: smtp; 554 4.4.7 Message expired: unable to deliver in 840 minutes.<421 4.4.2 Connection timed out>
Diagnostic-Code: smtp; 550 4.4.7 Message expired: unable to deliver in 840 minutes.<421 4.4.2 Connection closed unexpectedly>
Diagnostic-Code: smtp; 554 4.4.7 Message expired: unable to deliver in 840 minutes.<421 4.4.0 Unable to lookup DNS for ANOTHERDOMAIN.191.it>

尤其是这个错误：

Diagnostic-Code: smtp; 554 4.4.7 Message expired: unable to deliver in 840 minutes.<421 4.4.0 Unable to lookup DNS for sitedomain.it>

为了保护隐私，我更换了域名，但错误涉及不同的域名。

要查看它们，我有“返回路径”。在使用 Amazon 之前，我使用的是私有 SMTP，但我从未收到过这些消息。

好像很多地址是错误的或不存在的，但为什么我之前没有得到它们？

解释是什么？

Spamassassin 得分高

我使用这个工具：http://spamcheck.postmarkapp.com/ 来检查发送的电子邮件的质量，分数总是在 3 到 5 之间。

我的电子邮件只是 HTML 格式，并且只包含指向我的商业网站的链接。它们是给我的客户的新闻、优惠或类似的东西（他们选择了时事通讯）。

我为域启用了 DKIM。

如何生成更好的 HTML 以降低 spamassasin 分数并避免垃圾邮件？

这是完整的消息，包括完整的标题和内容：

【问题讨论】：

我投票决定将此问题作为离题结束，因为它似乎不是编程问题。调试外部垃圾邮件问题对于Stack Overflow 来说太宽泛了
还有很多关于 amazon ses 及其用法的信息。我在这里没有看到违规行为。我正在寻求反馈，如果您不能提供反馈，那么如果您不在这里浪费时间会更好。 ;)

标签： amazon-web-services spam-prevention amazon-ses

【解决方案1】：

我看到的第一件事是 SpamAssassin 服务器正在使用 ahbl.org，它不是一个活动的黑名单服务器。

2015 年 1 月 1 日，他们更改了黑名单，以便所有查询都以垃圾邮件的肯定结果响应。这是您用来测试 spamassassin 的服务器之一吗？如果是这样，请使用当前的黑名单更新您的黑名单。这将为您的 spamassassin 分数节省 2 分。

他们在这里发布了一条关于它的消息。 http://www.ahbl.org/content/last-notice-wildcarding-services-jan-1st

解决您对 SES 日志的其他顾虑

这意味着 Amazon SES 找不到该域的 DNS 记录。你确定它有效吗？检查 http://www.mxtoolbox.com 上的 MX 记录 Amazon SES 提供的反馈比其他 SMTP 服务器多。有可能在这些相同的电子邮件失败之前，但您没有得到日志数据来告诉您。

【讨论】：

您好，格雷格，非常感谢您的留言。我正在研究这些东西，我会告诉你我将要做什么。祝你有美好的一天
