Question

我尝试使用SSL配置postfix。我已经按照本教程进行了操作： https://www.cloudjojo.com/how-to-install-mail-server-on-ubuntu-14-04-part2/

当我从控制台向我的Gmail邮箱发送邮件时，邮件会被传递，但会发送到垃圾邮件。 Gmail表示此邮件具有标准的tsl加密（灰锁）。我究竟做错了什么？我需要完全加密，电子邮件不会发送垃圾邮件。

文件1710371.key仅包含密钥文件1710371.cert包含我的域的证书和文件certificate_and_key.crt包含我的域，密钥和两个中间证书的证书： 1. http://repository.certum.pl/hsha2.pem 2. http://repository.certum.pl/gscasha2.pem

如果您想使用更好的“标准TLS加密”，则需要以S / MIME的形式使用端到端加密。端到端意味着从邮件发件人到收件人，这意味着这只能用于您的邮件客户端，而不能用于邮件服务器，而邮件服务器只是一个跳，而不是邮件传输的端点。

请参阅Google Help了解各种符号的含义以及使用S / MIME需要执行的操作。

我需要完全加密电子邮件不会发送垃圾邮件。

只有一小部分邮件使用S / MIME。应该可以使用标准TLS加密或根本不加密，不能归类为垃圾邮件。您的服务器更有可能在某个黑名单中更早发送垃圾邮件，您尝试从正常的私有系统（即DSL，电缆或类似网站而不是互联网上的真实服务器）发送邮件，其他东西是混乱的根据您的设置，或者只是根据内容将您尝试发送的邮件视为垃圾邮件。

Postfix SSL不起作用，邮件转到垃圾邮件
