Google is rolling out a new feature available to everyone that can have sensitive emails destroy themselves as preset, if Confidential Mode is enabled in Gmail.
谷歌正面向所有用户推出一项新功能，只要启用Gmail机密模式，用户即可预设敏感电子邮件进行自毁。
The updated feature, which Google announced earlier this year, has become available to all its Gmail users, including both web-based or mobile phone customers, according to the US tech giant.
这家美国科技巨头透露，Gmail的所有用户--网页端或手机端用户，都可使用这项今年早些时候公布的更新功能。
"You can send messages and attachments with Gmail's Confidential Mode to help protect sensitive information from unauthorized access," Google said.
谷歌方面表示：“用户可通过Gmail的机密模式发送邮件和附件，有助于防止敏感信息被非授权访问。”

Confidential Mode prevents recipients from forwarding an email to other people, copying or pasting anything from its contents, downloading the message or printing it.
机密模式可以禁止收件人将邮件转发给他人、复制、粘贴邮件内容以及下载、打印邮件。
When Confidential Mode is on, users can decide how long an email exists before it deletes itself from a recipient's inbox, and the sender-defined expiration date ranges from one day to five years.
启用机密模式后，用户可决定邮件的存在期限，发件人可以设定的到期日期从1天到5年不等，到期后邮件将从收件人的收件箱中消失。
Google also allows users to revoke access by opening a confidential email and selecting "Remove access" to stop the recipient from viewing the email before the expiration date.
此外，谷歌还允许用户撤销访问权限，只需打开机密邮件、选择“移除访问权限”，即可在邮件到期之前禁止收件人阅读邮件。
