我可以使用哪些选项从我的 VPS 发送电子邮件（IP 列入黑名单）

我在 Debian 7 上运行 Postfix 和 Dovecot，我可以正常发送邮件，但发送到 Google 帐户时邮件总是进入垃圾邮件文件夹。另一位不使用 Gmail 的用户表示邮件已发送到他的收件箱。当我向自己发送测试邮件时，我收到以下标头：

我注意到了

Received-SPF: softfail (google.com: domain of transitioning [email protected] does not designate 2605:f700:100:400::875a:4b61 as permitted sender) client-ip=2605:f700:100:400::875a:4b61;
    Authentication-Results: mx.google.com;
           spf=softfail (google.com: domain of transitioning [email protected] does not designate 2605:f700:100:400::875a:4b61 as permitted sender) [email protected]

我认为这意味着我的 SPF TXT DNS 记录有问题：v=spf1 a:fluidvector.com ~all，尽管 pySPF 说它是好的。

我查看了 mxtoolbox.com，发现不知为何，我的 IP（从 VPS 提供商处获得）似乎被列入了 Barracuda 和 spamcannibal 的黑名单。我联系了我的 VPS 提供商，但他们似乎无法为我做任何事情。所以，目前我只能联系黑名单并请求删除我的 IP？我有什么选择？我可以让 gmail 将我服务器中的邮件发送到收件箱而不是垃圾邮件文件夹，而不必费心尝试取消列出？

答案1

被列入黑名单的 IP 很难取消列出，因为即使您可以修复已列出的 IP，也可能有许多其他黑名单服务器会阻止您，并且每家公司都可以维护自己的黑名单。如果您有一家成熟的企业，他们可能会与您合作，但他们可能会拒绝您的请求。

解决这个问题最简单的方法是使用第三方电子邮件服务就像 SendGrid 一样。如果您只发送事务性电子邮件，则可以使用 Postmark 或 Mandrill。您每月​​只需花费 1 美元即可使用 Sendgrid 发送数百封电子邮件。您将能够将它们添加到您的 SPF 记录中，这将显著提高您的传递率。
