! 如同传统信件在到达目的地前要经过多个邮局传递一样,Email的收发同样需要经过多次路由才能成功。在这个过程中,邮件的内容随时都可能被某些别有用心的人偷阅、复制、篡改或者删除。或许您对此并不知情,或许存有侥幸的心理,但无论如何,了解如何保证Email安全传送的方法是十分必要的。特别是当您的Email具有一定商业价值的时候,就更需要采取相应的手段来保证Email的安全了。 Just as traditional letters pass through multiple post offices before they reach their destination, sending and receiving emails also need to go through multiple routes to be successful. In the process, the content of the email may be stolen, copied, tampered with or deleted by some ulterior motives at any time. Perhaps you do not know this, there may be luck, but in any case, understanding how to ensure the safe delivery of Email is very necessary. Especially when your Email has a certain commercial value, it is even more necessary to take appropriate measures to ensure the safety of Email.
