我在 Server4You 上有一个专用服务器。该机器有 Debian 7.8 和 Plesk 11.5.30。
在服务器上我有 2 个网站，每个网站都有其各自的 IP 地址。
问题是我发送的所有邮件都被视为垃圾邮件，更糟糕的是，在 Outlook 帐户中甚至收不到电子邮件。
我的 Server4you 电源面板中的 DNS 反向是：mail.gupropiedades.cl for IP 69.64.49.24
这是我的 PLESK DNS 设置：

确保您的 DKIM 正常工作后：
我有完全相同的问题。每次测试都很好，就像你一样。问题在于用于发送电子邮件的自签名 SSL 证书。
如果您在向 Gmail 地址发送电子邮件时检查服务器日志，您会收到类似“不受信任的连接”的信息。显然 gmail 等不喜欢这个。
有一天，我决定用合法的证书替换自签名证书，突然间 Gmail 等上不再有垃圾邮件。它已经工作很长时间了。
我在该服务器上使用免费的让我们加密证书并且它有效。但为了使其正常工作，您需要检查一些事项：
在你的机器上安装 let's encrypt:
cd /etc/ssl/certs openssl dhparam -out dhparam.pem 4096 cd ~ git clone https://github.com/letsencrypt/letsencrypt && cd letsencrypt为您的服务器主机名生成 sandalone SSL：
(stop all web servers) cd ~/letsencrypt ./letsencrypt-auto --server https://acme-v01.api.letsencrypt.org/directory auth -d host.domain.dev添加让我们加密中间证书到您的系统；
Postfix 需要的证书为：
smtp_tls_CApath = /etc/ssl/certs smtpd_tls_key_file = privkey.pem smtpd_tls_cert_file = cert.pem smtpd_tls_CAfile = chain.pem
tail -f /var/log/mail.log发送电子邮件时务必检查 postfix 日志，以确保一切正确。如果是，您应该看到：Trusted TLS connection established to gmail-smtp-in。如果出现故障，postfix 会抱怨连接不受信任/找不到证书、CA 等。
聚苯乙烯：也许你应该尝试 EXIM，通常大型提供商在垃圾邮件方面比 Postfix 更喜欢它。
