推荐答案

为了避免垃圾邮件引擎将您的邮件分类为垃圾邮件，您应该:

Chiefly, to avoid a spam engine classifying your messages as spam you should:

• 确保它们不是垃圾邮件(即确保只有真正选择加入的用户才能收到邮件 - 确保保留选择加入的审核日志)
• 确保它们看起来不太像垃圾邮件 - $$$ MAKE MONEY FAST 不是一个好的主题行
• 确保发件人地址没有被欺骗，并且看起来没有被欺骗.使用您有权发送的域(如果您愿意，可以添加有效的 SPF 记录)
• 不要做任何看起来像恶意软件的事情(例如，包含脚本、表单、flash 等的 HTML 电子邮件)

但总的来说，主要的是:

But by and large the main one is:

• 请勿从以发送垃圾邮件而闻名的 IP 地址发送邮件.

最后一点意味着您不能使用共享主机.几乎所有共享主机提供商都允许发送不符合上述任何一项的邮件.共享主机提供商的中继几乎总是在许多黑名单上.

The last point means that YOU CANNOT USE SHARED HOSTING. Almost all shared hosting providers allow the sending of mails which don't conform to any of the above. Shared hosting providers' relays are almost always on lots of blacklists.

您的共享主机上只需要一个易受攻击的网络应用程序就可以变成垃圾邮件网关 - 这是您负担不起的.

It only takes one vulnerable web app on your shared hosting for it to turn into a spam gateway - something which you can't afford.

哦，是的 - 如果您没有设置信封发件人，您的托管服务提供商可能会将其设置为愚蠢的 - 确保您将其设置为与 From 相同: - 这可以确保您的邮件是'不被视为欺骗

Oh yes - if you're not setting the envelope-sender, your hosting provider may have it set to something stupid - ensure that you do set it to the same as From: - this makes sure that your messages aren't seen as spoofed
