附注我通过其他服务检查了我的服务器(向 mail.io、mail.com、mail.ru 发送消息) 它工作正常。我可以毫无问题地向此服务发送邮件,但 gmail 继续阻止我的邮件。我需要什么来解决这个问题?

成功发送邮件至mail.com、mail.ru

从 Gmail 接收我的消息

在 Gmail 中注册发送电子邮件地址并等待其通过身份验证。 Gmail 仅接受来自 Gmail 地址或已知与 Gmail 帐户关联的地址的邮件。

正如 Juan 在他的回复中提到的这里,您可能需要添加所需的 DNS TXT 记录。或者,您可以查看 Google Postmaster Tools。它可能会对当前的问题有所启发。

您需要确保在 https://postmaster.google.com/

上验证您的域名

未经身份验证的电子邮件通常会被拒绝或标记为垃圾邮件,以保护收件人免受网络钓鱼诈骗。出于安全原因,未经身份验证的带有附件的电子邮件可能会被完全拒绝。

为了确保 Gmail 可以对您进行身份验证:

  • 从同一IP地址发送

  • 保留指向您域的 IP 地址的有效反向 DNS 记录

  • 在“发件人:”标头中为每条批量消息选择相同的地址

对于

mail.sporta.io
反向 DNS 解析 - 未找到 PTR 记录。

对于

dmarc:sporta.io
未找到 DNS 记录。

对于

spf:sporta.io
未找到 DNS 记录。
