If you do this, your information won’t be encrypted for your protection. 我们建议您通过安全（加密）连接发送电子邮件。但是，如果您的其他邮件服务不支持这些安全连接或不使用有效证书，您可以选择端口 25，然后选择出现的“不安全连接”选项。如果这样做，您的信息将不会被加密保护。

Use Gmail aliases 使用 Gmail 别名

Filter using your Gmail alias: An easy way to sort your email is to add categories after your username. For example, messages sent to the following aliases will all go to janedoe@gmail.com: janedoe+school@gmail.com, janedoe+notes@gmail.com, janedoe+important.emails@gmail.com. 使用 Gmail 别名进行过滤：整理电子邮件的一个简单方法是在用户名后添加类别。例如，发送到以下别名的邮件都会进入 janedoe@gmail.com：janedoe+school@gmail.com、janedoe+notes@gmail.com、janedoe+important.emails@gmail.com。

Step 1: Choose aliases 第 1 步：选择别名

Think of how you want to sort your email, then choose an alias for each category. For example: Use yourname+work@gmail.com for work emails; Use yourname+news@gmail.com to sign up for newsletters; Use yourname+shopping@gmail.com to create an account with an online retailer. 考虑您希望如何整理邮件，然后为每个类别选择一个别名。例如：使用 yourname+work@gmail.com 处理工作邮件；使用 yourname+news@gmail.com 订阅新闻通讯；使用 yourname+shopping@gmail.com 在在线零售商处创建账户。

Step 2: Filter your messages 第 2 步：过滤您的邮件

Create filters to take automatic actions, like: Adding a label or a star; Forwarding to another account; Archiving or deleting. 创建过滤器以执行自动操作，例如：添加标签或星标；转发到其他账号；归档或删除。

Send from a work or school group alias 使用工作或学校群组别名发送邮件

If you use Gmail with your work or school account, you can send from a group alias. To receive the verification email to send from a group alias, you need to give delegates access to the group. 如果您使用工作或学校账号使用 Gmail，则可以使用群组别名发送邮件。要接收用于群组别名发送邮件的验证邮件，您需要授予代理人访问该群组的权限。

Important: Aliases aren’t private and sometimes they’re visible to others. For example, if you search Gmail for messages from bill@school.edu, you might find messages from alias@school.edu. You’ll need access to the group’s permissions to change access for other members. 重要提示：别名并非私密，有时会被他人看到。例如，如果您在 Gmail 中搜索来自 bill@school.edu 的邮件，可能会找到来自 alias@school.edu 的邮件。您需要拥有群组权限才能更改其他成员的访问权限。
