从我的 POSTFIX 邮件服务器发送的邮件进入 gmail 垃圾邮件

Question

我在我的 VPS 上设置了一个 POSTFIX 服务器，通过它发送的邮件将被发送到 gmail 中的垃圾邮件。这是我的留言：

如您所见，我的邮件服务器设置如下：

• 服务器有 DKIM
• 服务器有经过验证的签名证书
• SPF(TXT) 设置正确
• 服务器的 PTR（反向 DNS）正确指向我的邮件服务器
• 所有可能的检查工具都会为服务器提供最大的结果（每个人都应该信任它）

然而，gmail 会将来自所有域的所有邮件发送到垃圾邮件。有谁知道原因可能是什么或者我应该采取什么步骤？我可以联系某人吗？

提前致谢。

不确定下面的解决方案是否适合您，但它对我有用，因为我遇到了类似的问题。我使用传输映射有选择地选择以 @gmail.com 作为目标地址的邮件，并使用我的 G-Mail 凭据进行身份验证通过 smtp.gmail.com 中继它们。

步骤如下：

将以下条目添加到 /etc/postfix/transport

gmail.com smtp:[smtp.gmail.com]

将以下条目添加到 /etc/postfix/sasl_passwd

[smtp.gmail.com]:587            sgenov@gmail.com:<your_gmail_password_here>

将以下条目添加到 /etc/postfix/main.cf

transport_maps = hash:/etc/postfix/transport
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_tls_CAfile = /etc/postfix/ssl/cacert.pem
smtp_use_tls = yes

sudo chmod 400 /etc/postfix/sasl_passwd
sudo postmap /etc/postfix/sasl_passwd
sudo postmap /etc/postfix/transport
