This unauthorized access can happen while an email is in transit, as well as when it is stored on email servers or on a user computer. In countries with a constitutional guarantee of the secrecy of correspondence, whether email can be equated with letters and get legal protection from all forms of eavesdropping comes under question because of the very nature of email. This is especially important as more and more communication occurs via email compared to postal mail. Email has to go through potentially untrusted intermediate computers (email servers, ISPs) before reaching its destination, and there is no way to tell if it was accessed by an unauthorized entity. This is different from a letter sealed in an envelope, where by close inspection of the envelope, it might be possible to tell if someone opened it. In that sense, an email is much like a postcard whose contents are visible to everyone who handles it. There are certain technological workarounds that make unauthorized access to email hard, if not impossible. However, since email messages frequently cross nation boundaries, and different countries have different rules and regulations governing who can access an email, email privacy is a complicated issue. == Technological workarounds == There are some technical workarounds to ensure better privacy of email communication. Although it is possible to secure of the content of the communication, protecting the metadata of (who sent email to whom) is fundamentally hard.〔Mattingly, Phil. ("Why Email Can't Be Protected From Government Surveillance" ), ''MakeUseOf'', 21 August 2013. Retrieved on 2 April 2015.〕 Even though certain technological measures exist, the widespread adoption is another issue because of reduced usability. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Email privacy」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
