这里我展示了一封发往 Yahoo 的邮件,这些邮件直接落入了垃圾邮件文件夹。SPF 顺利通过,DKIM 顺利通过,甚至 DMARK 也顺利通过,但还是一直落入垃圾邮件文件夹。

答案1
您可以尝试将电子邮件发送到其他电子邮件服务吗?
如果雅虎之前已将发件人检测为垃圾邮件,那么现在可能存在一条电子邮件规则,将来自该发件人的所有邮件移至垃圾邮件文件夹。
您是否尝试过发送到 Gmail 地址或其他电子邮件提供商?
答案2
即使有效域名解析,防晒指数和 密钥管理信息系统,Yahoo 仍可能将您的电子邮件放入其垃圾邮件文件夹。可能的原因是您的 IP 地址被列入 Yahoo 黑名单,因为以前的网站管理员/管理员使用您的 IP 发送垃圾邮件。
根据我过去与该提供商合作的经验,可能需要几天时间/一些合法的电子邮件才能重建与 Yahoo MX 的信任关系。当时我采纳的一些建议是填写 Yahoo! 邮件批量发送表单。它允许您告诉雅虎您拥有什么样的邮件服务器设置,以便他们可以将您的电子邮件路由到适当的文件夹。
答案3
我添加了 TXT-SPF 记录以允许目标邮件服务器进行验证。
@ TXT "v=spf1 include:_spf.telenet.be a:pieterjan.pro ~all"
有了这个记录,我发送的邮件就会直接进入收件箱,而不是垃圾邮件。
我认为邮件服务器通过挑战发件人字段来过滤垃圾邮件(例如[电子邮件保护]) 到出现的域名 (pieterjan.pro) 关联的 DNS 记录。
如果 pieterjan.pro 的 DNS 包含上述记录,则邮件服务器会信任从其他邮件中心(例如 smtp.telenet.be)发送的电子邮件,但发件人字段会被更改。
