了解安全电子邮件 [英] Understanding Secure Email

问题描述

我有一个关于使用SSL保护电子邮件的问题。

如果我获得SSL证书来保护我的电子邮件，那意味着我的邮件之间的连接客户端和我的邮件服务器将被加密。所以听的人都无法查看我的电子邮件或用户名和密码。但邮件服务器和目标邮件服务器之间会发生什么？在那里和收件人的邮件客户端之间？如果用户不使用SSL，电子邮件及其内容是否仍然安全？

另外，出于兴趣，是人们听的危险从您的内部网络（使用数据包嗅探者的人员）还是在云中听到人们的危险？

谢谢，

Michael

解决方案

这仅保护邮件客户端和邮件服务器之间的连接/通信。 p>

所以内部网络上的人不能嗅探（至少不是明文）你的邮件。

邮件服务器从服务器到接收方的服务器之间的传输取决于其配置。

基本上，您无法避免某些邮件服务器操作员阅读的风险您的邮件或NSA阅读，等等...

唯一要保护您的邮件与恶意邮件服务器操作员的事情是加密y我们的邮件中包含一些公钥加密系统（例如， PGP）。

I've got a question about securing emails with SSL.

If I get an SSL certificate to secure my email, that would mean that the connection between my mail client and my mail server will be encrypted. So anyone listening in couldn't view my emails or username and password. But what happens between the mail server and the destination mail server? And between there and the recipient's mail client? If the reciepient isn't using SSL, will the email and it's contents still be secure?

Also, out of interest, is the danger of people "listening in" just from your internal network (people using packet sniffers) or is there a danger of people out in the cloud listening in?

Thanks,

Michael

解决方案

This only secures the connection/communication between your mail client and the mail server.

So people on your internal network can't sniff (at least not in clear text) your mail.

How the transport between the mail server from your server to the server of the recipient happens depends on their configuration.

Basically you can't avoid the risk of some mail server operator reading your mail, or the NSA reading it, and so on...

The only thing to secure your mail against a malicious mail server operator would be to encrypt your mail with some Public-key cryptography system (e.g. PGP).
